Hinako Sugiura(杉浦日向子Sugiura Hinako, November 30, 1958 – July 22, 2005) was a manga artist and researcher in the lifestyles and customs of Japan's Edo period. Born Junko Suzuki in Minato, Tokyo, into a tradition-steeped family of kimono merchants, she studied design and took an increasing interest in old Japan. She attended Nihon University, but gave up her formal studies to pursue research under the direction of author Shisei Inagaki. Inagaki specialized in the Edo period and taught Sugiura how to do the background surveys that would later ensure the historical accuracy of her manga and other works.
