Matsuura Takeshirō (松浦 武四郎, 12 March 1818 – 10 February 1888) was a Japanese explorer, cartographer, writer, painter, priest, and antiquarian. During the late Edo period and Bakumatsu he journeyed six times to Ezo, including to Sakhalin and the Kuriles. In the early Meiji period he was an official in the Hokkaidō Development Commission. Instrumental in the naming of the island and many of its places, he is sometimes referred to as the "godparent of Hokkaidō". Source: Wikipedia (en)
