Hisako Hibi née Shimizu (1907-1991) was a Japanese American artist in Hayward and San Francisco, California. She was married to artist Matsusaburo "George" Hibi (1886-1947). Both artists were active members of the San Francisco Bay Area arts community. The two met at the California School of Fine Arts (renamed the San Francisco Art Institute, which closed in 2022) and married in 1930. They had two children, Satoshi and Ibuki. Both Hisako and Matsusaburo "George" Hibi exhibited their paintings widely.
In 1942, the entire Hibi family was forcibly removed and incarcerated at the Tanforan Assembly Center in California and subsequently the Topaz Relocation Center in Utah where they remained until the end of World War II. After the war, the family moved to New York City, where Matsusaburo "George" Hibi passed away in 1947. Hisako Hibi worked as a seamstress at a garment factory and later studied painting at the Museum of Modern Art. In the early 1950s, Hisako Hibi and her daughter Ibuki returned to San Francisco. Hisako Hibi continued to exhibit frequently in group and solo shows. She passed away in 1991.
