Sadahide Hashimoto (橋本貞秀) (1807 - 1878) was a Japanese pro-foreign artist active in Yokohama in the second half of the 19th century. He was born in Chiba Prefecture. Hashimoto is best known for his renderings of foreigners, in particular Western peoples and customs, as observed while living in the open port of Yokohama. He is considered to be a disciple of Takako Kunisada, another artist of the Toyokuni Utagawa school. Hashimoto met Kunisada in 1826, when he was 14 years old and most of his early work reflects the work of Kunisada. From about 1859 onwards he developed an interested in geography and began issuing maps and bird's-eye views, some quite large over multiple panels, of Japanese cities. He was a mentor to Hideki Utagawa.
