in 1604, "shōgun" tokugawa ieyasu ordered william adams and his companions to build japan's first western-style sailing ship at itō, on the east coast of the izu peninsula. an 80-ton vessel was completed and the "shōgun" ordered a larger ship, 120 tons, to be built the following year (both were slightly smaller than the "liefde", the ship in which william adams came to japan, which was 150 tons). according to adams, ieyasu "came aboard to see it, and the sight whereof gave him great content". the ship, named "san buena ventura", was lent to shipwrecked spanish sailors for their return to mexico in 1610.
