William Adams (September 24,1564–May 16, 1620), also known in Japanese as Anjin-sama (anjin, "pilot"; sama, a Japanese honorific) and Miura Anjin (三浦按針: "the pilot of Miura"), was an English navigator who travelled to Japan and is believed to be the first Briton ever to reach that country. He was the inspiration for the character of John Blackthorne in James Clavell's bestselling novel Shogun.

Soon after Adams' arrival in Japan, he became a key advisor to the shogun Tokugawa Ieyasu and built for him Japan's first Western-style ships. Adams was later the key player in the establishment of trading factories by the Netherlands and England. He was also highly involved in Japan's Red Seal Asian trade, chartering and captaining several sailboats to Southeast Asia. He died in Japan at age 56, and is recognized to this day as one of the most influential foreigners during Japan's first period of opening to the West.

Adams was born in Gillingham, Kent, England. After losing his father at the age of twelve, he was apprenticed to shipyard owner Master Nicholas Diggins at Limehouse for the seafaring life. He spent the next twelve years learning shipbuilding, astronomy, and navigation before entering the Royal Navy.

Adams served in the Royal Navy under Sir Francis Drake and saw naval service against the Spanish Armada in 1588 as master of the Richarde Dyffylde, a resupply ship.

Adams then became a pilot for the Barbary Company. During this service, according to Jesuit sources, he took part in an expedition to the Arctic that lasted about two years, in search of a Northeast Passage along the coast of Siberia to the Far East.

…I am a Kentish man, born in a town called Gillingham, two English miles from Rochester, one mile from Chatham, where the King's ships do lie: from the age of twelve years old, I was brought up in Limehouse near London, being Apprentice twelve years to Master Nicholas Diggins; and myself have served for Master and Pilot in her Majesty's ships; and about eleven or twelve years have served the Worshipfull Company of the Barbary Merchants, until the Indish traffic from Holland began, in which Indish traffic I was desirous to make a little experience of the small knowledge which God had given me. So, in the year of our Lord 1598, I was hired for Pilot Major of a fleet of five sails, which was made ready by the Dutch Indish Company…. (1611 Letter, William Adams)

Attracted by the Dutch trade with India, Adams, then 34 years old, shipped as pilot major with a five ship fleet dispatched from the isle of Texel to the Far East in 1598 by a company of Rotterdam merchants (a voorcompagnie, anterior to the Dutch East India Company).



He set sail from Rotterdam in June 1598 on the Hoop and joined up with the rest of the fleet on June 24. The fleet consisted of: * the Hoop ("Hope"), under Jacques Mahu (†1598), expedition leader, succeeded by Simon de Cordes (†1599), and finally, Jan Huidekoper, * the Liefde ("Love" or "Charity"), under Simon de Cordes, 2nd in command, succeeded by Gerrit van Beuningen and finally under Jacob Kwakernaak, * the Geloof ("Faith"), under Gerrit van Beuningen, and in the end: Sebald de Weert, * the Trouw ("Loyalty"), under Jurriaan van Boekhout (†1599), and finally, Baltazar de Cordes, * the Blijde Boodschap ("Good Tiding" or "The Gospel"), under Sebald de Weert, and later, Dirck Gerritz.

Originally, the fleet's mission was to sail for the west coast of South America, where they would sell their cargo for silver, and to head for Japan only if the first mission failed. In that case, they were supposed to obtain silver in Japan to buy spices in the Moluccas, before heading back to Europe.

The vessels, boats ranging from 75 to 250 tons and crowded with men, were driven to the coast of Guinea, West Africa where the adventurers attacked the island of Annabon for supplies, and then moved on for the Straits of Magellan. Scattered by stress of weather and after several disasters in the South Atlantic, only three ships out of five made it through the Magellan Straits. (The Blijde Boodschap was adrift after being disabled in bad weather and was captured by the Spanish, whereas the Geloof returned to Rotterdam in July 1600 with 36 of the original 109 crew.

During the voyage, Adams had changed ships to the Liefde (originally Erasmus and adorned by a wooden Erasmus on her stern . The Liefde waited for the other ships at Santa Maria Island off the Chilean coast. However, only the Hoop had arrived by the spring of 1599 and the captains of both vessels, together with Adams's brother Thomas and twenty other men, lost their lives in an encounter with the natives. The Trouw later turned up in Tidore (Indonesia) where the crew was eliminated by the Portuguese in January 1601).

In fear of the Spaniards, the remaining crews determined to sail across the Pacific. It was late November 1599 when the two ships sailed westwardly for Japan. On their way, the two ships made landfall in "certain islands" (possibly the islands of Hawaii) where eight sailors deserted the ships. Later during the voyage, a typhoon claimed the Hoop with all hands, in late February 1600.

In April 1600, after more than nineteen months at sea, the Liefde with a crew of about twenty sick and dying men (out of an initial crew of about 100) was brought to anchor off the island of Kyūshū, Japan. Its cargo consisted of eleven chests of coarse woollen cloth, glass beads, mirrors, spectacles, nails, iron, hammers, nineteen bronze cannon, 5,000 cannonballs, 500 muskets, 300 chain-shot and three chests filled with coats of mail.

When the nine crew members strong enough to stand made landfall on April 19 off Bungo (present-day Usuki, Ōita Prefecture), they were met by locals and Portuguese Jesuit priests claiming that Adams' ship was a pirate vessel and that the crew should be crucified as pirates. The ship was seized and the sickly crew were imprisoned at Osaka Castle on orders by Tokugawa Ieyasu, the daimyo of Mikawa and future Shogun. The nineteen bronze cannon of the Liefde were unloaded and according to Spanish accounts later employed at the decisive Battle of Sekigahara on October 21 1600.

Adams met Ieyasu in Osaka three times between May and June 1600. He was questioned by Ieyasu, then a guardian of the young son of the Taikō, Toyotomi Hideyoshi, the ruler who had just died. Adams' knowledge of ships, shipbuilding and nautical smattering of mathematics appealed to Ieyasu.

Coming before the king, he viewed me well, and seemed to be wonderfully favorable. He made many signs unto me, some of which I understood, and some I did not. In the end, there came one that could speak Portuguese. By him, the king demanded of me, of what land I was, and what moved us to come to his land, being so far off. I showed unto him the name of our country, and that our land had long sought out the East Indies, and desired friendship with all kinds and potentates in way of merchandise, having in our land diverse commodities, which these lands had not … Then he asked whether our country had wars? I answered him yea, with the Spaniards and Portugals, being in peace with all other nations. Further, he asked me, in what I did believe? I said, in God, that made heaven and earth. He asked me diverse other questions of things of religion, and many other things: as what way we came to the country. Having a chart of the whole world, I showed him, through the Strait of Magellan. At which he wondered, and thought me to lie. Thus, from one thing to another, I abode with him till midnight. (William Adams's letter to his wife)

Adams further explained that Ieyasu finally denied the Jesuits' request for punishment on the ground that:

we as yet had not done to him nor to none of his land any harm or damage; therefore against Reason or Justice to put us to death. If our country had wars the one with the other, that was no cause that he should put us to death; with which they were out of heart that their cruel pretence failed them. For which God be forever praised. (William Adams's letter to his wife)

Ieyasu ordered the crew to sail the Liefde from Bungo to Edo where, rotten and beyond repair, she sank.

In 1604, Ieyasu ordered Adams and his companions to help Mukai Shogen, who was commander in chief of the navy of Uraga, build Japan's first Western-style ship. The sailship was built at the harbour of Ito on the east coast of the Izu Peninsula, with carpenters from the harbour supplying the manpower for the construction. An eighty-ton vessel was completed which was employed to survey the Japanese coast. The Shogun then ordered a larger ship, 120 tons, to be built the following year (both were slightly smaller than the Liefde, which was 150 tons). According to Adams, Ieyasu "came aboard to see it, and the sight whereof gave him great content". In 1610, the 120-ton ship (later named San Buena Ventura) was lent to shipwrecked Spanish sailors, who sailed back to Mexico with it, accompanied by a mission of twenty-two Japanese led by Tanaka Shosuke.

Following the construction, Ieyasu invited Adams to visit his palace whenever he liked and "that always I must come in his presence" (Letters).

Other survivors of the Liefde were also rewarded with favours and even allowed to pursue foreign trade. Most of the original crew were able to leave Japan in 1605 with the help of the daimyo of Hirado. Although Adams did not himself receive permission to leave Japan until 1613, Melchior van Santvoort, together with another crewman, Jan Joosten van Lodensteijn, engaged in trade between Japan and Southeast Asia and reportedly made a fortune. Both of them were reported by Dutch traders in Ayutthaya, onboard richly cargoed junks, in early 1613.

Around 1608 Adams contacted the interim governor of the Philippines, Rodrigo de Vivero y Velasco on behalf of Tokugawa Ieyasu, who wished to establish direct trade contacts with New Spain. Friendly letters were exchanged, officially starting relations between Japan and New Spain.

Adams is also recorded as having chartered Red Seal Ships during his later travels to Southeast Asia (the Ikoku Tokai Goshuinjō has a reference to Miura Anjin receiving a shuinjō, a document bearing a red Shogunal seal authorizing the holder to engage in foreign trade, in 1614).

The shogun took a liking to Adams and made him a revered diplomatic and trade adviser and bestowed great privileges upon him. Ultimately, Adams became his personal advisor on all things related to Western powers and civilization and, after a few years, Adams replaced the Jesuit Padre João Rodrigues as the Shogun's official interpreter. Padre Valentim Carvalho wrote: "After he had learned the language, he had access to Ieyasu and entered the palace at any time"; he also described him as "a great engineer and mathematician".



Adams had a wife and children in England but Ieyasu had forbidden the Englishman to leave Japan. He was presented with two swords representing the authority of a Samurai. The Shogun decreed that William Adams the pilot was dead and that Miura Anjin (三浦按針), a samurai, was born. This made Adams's wife in England in effect a widow (although Adams managed to send regular support payments to her after 1613 via the English and Dutch companies) and "freed" Adams to serve the Shogunate on a permanent basis. Adams also received the title of hatamoto (bannerman), a high-prestige position as a direct retainer in the Shogun's court.

He was provided with generous revenues: "For the services that I have done and do daily, being employed in the Emperor's service, the emperor has given me a living" (Letters). He was granted a fief in Hemi (Jpn: 逸見) within the boundaries of present-day Yokosuka City, "with eighty or ninety husbandmen, that be my slaves or servants" (Letters). His estate was valued at 250 koku (measure of the income of the land in rice equal to about five bushels). He finally wrote "God hath provided for me after my great misery" (Letters) by which he meant the disaster-ridden voyage that had initially brought him to Japan.

Adams's estate was located next to the harbour of Uraga, the traditional point of entrance to Edo Bay where he is recorded to have dealt with the cargoes of foreign ships. John Saris related that when he visited Edo in 1613, Adams was in possession of the reselling rights for the cargo of a Spanish ship at anchor in Uraga Bay.

Adams' position gave him the means to marry Oyuki (お雪), the daughter of Magome Kageyu, a highway official who was in charge of a packhorse exchange on one of the grand imperial roads that led out of Edo (roughly present day Tokyo). Although Magome was important, he was not of noble birth, nor high social standing and so it was likely that Adams married out of true affection rather than for social reasons. Adams and Oyuki had a son called Joseph and a daughter named Susanna. Adams however found it hard to rest his feet and was constantly on the road. Initially, it was in the vain attempt to organize an expedition in search of the Arctic passage that had eluded him previously.

Adams had a high regard for Japan, its people, and its civilization:

The people of this Land of Japan are good of nature, curteous above measure, and valiant in war: their justice is severely executed without any partiality upon transgressors of the law. They are governed in great civility. I mean, not a land better governed in the world by civil policy. The people be very superstitious in their religion, and are of diverse opinions. (William Adams's letter to Bantam, 1612)

The Liefde's captain, Jacob Quaeckernaeck, and the treasurer, Melchior van Santvoort, were also sent by Ieyasu in 1604 on a shogun-licensed Red Seal Ship to Patani in Southeast Asia to contact the Dutch East India Company trading factory which had just been established there in 1602, to bring more western trade to Japan and break the Portuguese monopoly on Japan's external trade. In 1605, Adams obtained a letter from Ieyasu formally inviting the Dutch to trade with Japan.

Hampered by conflicts with the Portuguese and limited resources in Asia, the Dutch were not able to send ships until 1609. Two Dutch ships, commanded by Jacob Groenewegen, De Griffioen (the "Griffin", 19 cannons) and Roode Leeuw met Pijlen (the "Red lion with arrows", 400 tons, 26 cannons), were finally sent from Holland and arrived in Japan on July 2nd, 1609. They were assisted by one of Adams's shipmate Melchior van Santvoort for their preparations to establish a trading factory in Hirado, who also accompanied two Dutch delegates by the names of Puyck and van den Broek, bearing a letter from Prince Maurice of Nassau, to the court of Edo. Adams negotiated on their behalf with the Shogun and obtained free trading rights throughout Japan (in contrast, the Portuguese were only allowed to sell their goods in Nagasaki at fixed, negotiated prices) and to establish a trading factory there:

The Hollandes be now settled (in Japan) and I have got them that privilege as the Spaniards and Portingals could never get in this 50 or 60 years in Japan. (William Adams letter to Bantam).

After obtaining this trading right through an edict of Tokugawa Ieyasu on August 24th, 1609, the Dutch inaugurated a trading factory in Hirado on September 20th, 1609. The "trade pass" (Dutch: "Handelspas") was kept preciously by the Dutch in Hirado and then Dejima as a guarantee of their trading rights, during the following two centuries of their presence in Japan.

In 1611, news came to Adams of an English settlement in Bantam, Indonesia, and he sent a letter asking them to give news of him to his family and friends in England and enticing them to engage in trade with Japan which "the Hollanders have here an Indies of money" (Adams's letter to Bantam).

In 1613, the English Captain John Saris arrived at Hirado in the ship Clove with the intent of establishing a trading factory for the British East India Company (Hirado was already a trading post for the Dutch East India Company (the VOC)).

Adams met with Saris's ire over his praise of Japan and adoption of Japanese customs:

He persists in giving "admirable and affectionated commendations of Japan. It is generally thought amongst us that he is a naturalized Japaner." (John Saris)

In Hirado, Adams refused to stay in English quarters and instead resided with a local Japanese magistrate. It was also commented that he was wearing Japanese dress and spoke Japanese fluently. Adams estimated the cargo of the Clove was of little value, essentially broadcloth, tin and cloves (acquired in the Spice Islands), saying that "such things as he had brought were not very vendible".

Adams travelled with Saris to Shizuoka where they met with Ieyasu at his principal residence in September and then continued to Kamakura where they visited the famous Buddha (the 1252 Daibutsu on which the sailors etched their names) before moving on to Edo where they met Ieyasu's son Hidetada who was now nominally Shogun even though Ieyasu retained most of the actual decisionmaking powers. During that meeting, Hidetada gave Saris two varnished suits of armor for King James I, today housed in the Tower of London.



On their way back, they visited again Tokugawa, who conferred trading privileges to the English through a red-seal permit (Japanese: 朱印状) giving them "free license to abide, buy, sell and barter" in Japan. The English party headed back to Hirado on October 9, 1613.

On this occasion, Adams asked for and obtained Tokugawa's authorization to return to his home country. However, he ultimately declined Saris' offer to bring him back to England: "I answered him I had spent in this country many years, through which I was poor... [and] desirous to get something before my return". His true reasons seem to lie rather with his profound antipathy for Saris: "The reason I would not go with him was for diverse injuries done against me, the which were things to me very strange and unlooked for." (William Adams letters)



He accepted employment with the newly founded Hirado trading factory, signing a contract on November 24, 1613, becoming an employee of the East India Company for the yearly salary of 100 English Pounds, more than double the regular salary of 40 Pounds earned by the other factors at Hirado. Adams was to take a leading part, under Richard Cocks and together with six other compatriots (Tempest Peacock, Richard Wickham, William Eaton, Walter Carwarden, Edmund Sayers and William Nealson), in the organization of this new English settlement.

Adams had actually advised against the choice of Hirado which was small and far away from the major markets in Osaka and Edo and instead had recommend to Saris, in vain, that they should select Uraga near Edo.

During the ten year activity of the company between 1613 and 1623, apart from the first ship (the Clove in 1613), only three other English ships brought cargoes directly from London to Japan, invariably described as poor value on the Japanese market. The only trade which helped support the factory was that organized between Japan and South-East Asia and mainly undertaken by Adams selling Chinese goods for Japanese silver:

Were it not for hope of trade into China, or procuring some benefit from Siam, Pattania and Cochin China, it were no staying in Japon, yet it is certen here is silver enough & may be carried out at pleasure, but then we must bring them commodities to their liking. (Richard Cocks Diary, 1617)

Adams, a Protestant, was seen as a rival by the Portuguese and other Catholic religious orders in Japan. When he and his crew arrived on the Liefde, the Jesuits settled in Nagasaki became very anxious as they had informed the Japanese, inaccurately in fact, but not necessarily in their belief, that all Europe was united under a single, undisputed church. Because of the fear that Adams would shed light on the truth, the Jesuits conspired against him, asking forcefully for his crucifixion at first, then having him imprisoned when Ieyasu refused to kill Adams for no reason. Later, after Adams' power had grown, the Jesuits attempted first to convert him, then offered to secretly bear him away from Japan on a Portuguese ship. The fact that the Jesuits were willing to disobey the orders set down by Ieyasu—that Adams might not leave Japan—betray the degree to which they feared his influence—for good reason.

Catholic priests insisted that he was using his influence on Ieyasu to discredit them:

In his character of heretic, he constantly endeavoured to discredit our church as well as its ministers".. He and others "by false accusation ... have rendered our preachers such objects of suspicion that Ieyasu fears and readily believes that they are rather spies than sowers of the Holy Faith in his kingdoms. (Padre Valentim Carvalho).

Ieyasu, influenced by Adams' counsels and social trouble caused by the numerous Catholic converts, expelled the Jesuits from Japan in 1614 and demanded the Japanese Catholics abandon their faith.

Adams also apparently warned Ieyasu against Spanish approaches explaining that they typically tried to establish Catholic converts and strongholds as a prelude to the arrival of conquistadores and full invasion of the country as they had done in the Philippines, Mexico and Peru in the previous hundred years.

After fifteen years spent in Japan, Adams' relations with his compatriots were not the easiest. He initially shunned the company of the newly arrived English sailors in 1613 and could not get on good terms with Saris.

However, Cocks, the head of the Hirado factory, progressively came to appreciate Adams' character and distinctively Japanese self-control. In a letter to the East India Company:

"I find the man tractable and willing to do your worships the best service he may... I am persuaded I could live with him seven years before any extraordinary speeches should happen between us." (Cocks' Diary)

Adams later engaged in various exploratory and commercial ventures. He tried to organize the exploration of the Northern Passage from the East which would have greatly reduced the traveling distance between Japan and Europe. Ieyasu asked him if "our countrimen could not find the northwest passage" and Adams contacted the East India Company to organize manpower and supplies. The project however never materialized.

The latter part of his life was spent in the service of the English trading company. He undertook a number of voyages to Siam in 1616 and Cochin China in 1617 and 1618, sometimes for the English East India Company, sometimes for his own account. He is recorded in Japanese sources as the owner of a Red Seal Ship of 500 tons.

Given the small number of ships coming from England (four ships in ten years: the Clove in 1613, the Hosiander in 1615, the Thomas and the Advice in 1616) and the poor value of their cargoes (broadcloth, knives, looking glasses, Indian cotton, etc.), William Adams played a key role in having the company participate in the Red Seal system by obtaining trading certificates from the Shogun. Altogether, seven junk voyages were made to Southeast Asia with mixed results, including four of them headed by William Adams himself as Captain. Adams acknowledged God as his personal Provider before all people by renaming the ship, which he had acquired, with the phrase "Gift of God", the ship that he used for his expedition to Cochinchina.

In 1614, Adams wished to organize a trade expedition to Siam in hope of bolstering the factory's activities and cash situation. He bought for the factory and upgraded a 200-ton Japanese junk, renamed her the Sea Adventure, hired about 120 Japanese sailors and merchants as well as several Chinese traders, an Italian and a Castillan trader and the heavily laden ship left on November 1614, during the typhoon season. The merchants Richard Wickham and Edmund Sayers of the English factory's staff also participated to the voyage.

The ship was to purchase raw silk, Chinese goods, sappan wood, deer skins and ray skins (the latter used for the handles of Japanese swords), essentially carrying only silver (£1250) and £175 of merchandise (Indian cottons, Japanese weapons and lacquerware).

The ship met with a typhoon near the Ryukyu Islands (modern Okinawa) and had to stop there to repair from 27 December 1614 until May 1615 before returning to Japan in June 1615 without having been able to complete any trade.

Adams again left Hirado in November 1615 for Ayutthaya in Siam on the refitted Sea Adventure intent on bringing sappanwood for resale in Japan. Like the previous year, the cargo consisted mainly of silver (£600) and also the Japanese and Indian goods unsold from the previous voyage.

He managed to buy vast quantities of the profitable products, even buying two additional ships in Siam to transport everything. Adams sailed the Sea Adventure back to Japan with 143 tonnes of sappanwood and 3700 deer skins, returning to Hirado in 47 days, (the whole trip lasting between 5 June and 22 July 1616). Sayers, on a hired Chinese junk, reached Hirado in October 1616 with 44 tons of sappanwood. The third ship, a Japanese junk, brought 4,560 deer skins to Nagasaki in June 1617 after having missed the monsoon.

Adams returned to Japan less than a week after the death of Ieyasu and accompanied Cocks and Eaton to court to offer presents to the new ruler Hidetada. Although the death of Ieyasu in 1616 seems to have weakened Adams' political influence, Hidetada agreed to maintain the trading privileges of the English and issued a new Red Seal permit (Shuinjō) to Adams allowing him to continue trade activities overseas under the Shogun's protection. His position as hatamoto was also renewed.

On this occasion, Adams and Cocks also visited the Japanese Admiral Mukai Shogen Tadakatsu who lived near Adams' estate and they discussed plans about a possible invasion of the Catholic Philippines.

In March 1617, Adams set sail for Cochinchina having purchased the junk Sayers had brought from Siam and renamed it the Gift of God. He intended to find two English factors that had left Hirado two years before to explore commercial opportunities (the first voyage to South East Asia by the Hirado English Factory). He returned to Japan with the knowledge that both had been killed and robbed of their silver.

The ship also sold a small cargo of broadcloth, Indian piece goods and ivory for the modest amount of £351.

In 1618, Adams is recorded as having organized his last Red Seal trade expedition to Cochinchina and Tonkin (modern Vietnam), the last expedition of the English Hirado Factory to Southeast Asia. The ship, a chartered Chinese junk, left Hirado on 11 March 1618 but met with bad weather that forced it to stop at Ōshima in the northern Ryukyus. The ship sailed back to Hirado in May.

Those expeditions to Southeast Asia helped the English factory survive for some time (During that period, sappanwood resold in Japan with a 200% profit) until the factory fell into bankruptcy due to high expenditures.

Adams died at Hirado, north of Nagasaki, on May 16, 1620, aged 56 and was buried in Nagasaki-ken where his grave marker may still be seen to this day, alongside a memorial to Saint Francis Xavier. The English factory was dissolved three years later due to its unprofitability.

In his will, he left his townhouse in Edo, his fief in Hemi, and 500 British pounds to be divided evenly between his family in England and his family in Japan.

Cocks wrote: "I cannot but be sorrowfull for the loss of such a man as Capt William Adams, he having been in such favour with two Emperors of Japan as never any Christian in these part of the world" (Cocks's Diary)

Cocks remained in contact with Adams' family sending gifts and in March 1622, offering silks for Joseph and Susanna. He handed to Joseph his father's sword and dagger on the Christmas following Adams' death. Cocks also records that Hidetada transferred the lordship from William Adams to his son Joseph Adams with the attendant rights to the estate at Hemi:

He (Hidetada) has confirmed the lordship to his son, which the other emperor (Ieyasu) gave to the father (Cocks's Dairy)

Cocks was also in charge of using Adams' trading rights (the shuinjō) for the benefit of Adams' children, Joseph and Susanna, a task he performed conscientiously and which was handled by the Dutch after 1623.

By 1629, only two of Adams's shipmates were still surviving, living privately in Nagasaki: Melchior van Santvoort and Vincent Romeyn.



Adams' son also kept the title of Miura Anjin and was a successful trader until the closure of the country in 1635 when he disappeared from historical records.

Adams's memory is preserved in the naming of a town in Edo (modern Tokyo), Anjin-chō (in modern-day Nihonbashi), where he had a house and by an annual celebration on June 15 in his honour.

A village in his fiefdom, Anjinzuka (安針塚, "Burial mound of the Pilot"), in modern Yokosuka, bears his name.

Also, in the city of Itō, Shizuoka, the Miura Anjin Festival is held all day on August 10.

Today, both Itō and Yokosuka are sister cities of Adams' birth town of Gillingham.

The life of William Adams also inspired James Clavell's Shogun, which was a best-selling novel and then a celebrated TV miniseries. The fictional heroics of John Blackthorne were loosely based on Adams' adventures in the first few years after his arrival in Japan.

Altogether, four letters of William Adams are known, among which the letter to his wife and the letter to the English trading post at Bantam are the most informative. Some other famous quotes: * "Most of us are just about as happy as we make up our minds to be." * "Faith is a continuation of reason." * "As a nation of free men, we must live through all time, or die by suicide."
