札幌農学校
Aizō Sōma (1870–1954) was a Christian philanthropist who founded "Shinjuku Nakamuraya". Having received his secondary education in Matsumoto, he studied at "Tokyo Senmon Gakkō" (now Waseda University), and then at Sapporo Agricultural College (now Hokkaidō University). He returned to "Azumidaira" and established a successful silk worm business. He was involved in a campaign against drinking and brothels. He was one of the supporters of Kigenji Iguchi (see below). He married a girl named Ryō from Sendai, but she could not get used to rural life, and he moved his family to Tokyo where he founded a successful bakery called "Shinjuku Nakamuraya" with his wife.
