Birthplace of Nakahama Manjirō
On the western shore of Ashizuri peninsula, lies the village of Nakanohama within Tosashimizu, where Nakahama Manjirō was born and became one of the first Japanese to travel to the United States. Manjirō, a young fisherman, was shipwrecked off the coast of Japan in 1841 and rescued by whaling captain William H. Whitfield of Fairhaven, Massachusetts.[16] Whitfield brought the young Manjirō back to Fairhaven and New Bedford at the end of the whaling voyage, and Manjirō spent several years there before eventually making his way back to Japan. Because of this history, Tosashimizu became the sister city of both Fairhaven and New Bedford in 1987.[16] He became popular as John Manjirō after Ibuse Masuji depicted him in his novel John Manjiro. The Castaway: His Life and His Adventures.[17]
