Insider tip — Futo is a charming fishing harbor on the eastern Izu Peninsula, facing Sagami Bay toward the volcanic Ōshima Island (30 km offshore). The Izu Peninsula sits on the Philippine Sea Plate, giving it extraordinary geothermal resources; William Adams (the English sailor who became Japan's first Western samurai and inspired James Clavell's 'Shōgun') built Japan's first Western-style ships nearby in Itō (1604) for Tokugawa Ieyasu. Futo's small-boat harbor and sunrise views are exceptional.
