Etsuko Sugimoto (杉本 鉞子, Sugimoto Etsuko, 1874 – June 20, 1950), also known as Etsu Inagaki Sugimoto, was a Japanese American autobiographer and novelist. She was born Nagaoka in Echigo Province (which means "Behind the Mountains") in Japan, now part of Niigata Prefecture. Her father had once been a high-ranking samurai official in Nagaoka, but with the breakdown of the feudal system shortly before her birth, the economic situation of her family took a turn for the worse.
