Saito Yuki, born in Minami-Ku, Yokohama, Kanagawa Prefecture, is a Japanese singer-songwriter, actress, essayist, and poet. She was one of the most popular idols in the 1980s. Her married name is Isarai Yuki, though she continues to work under her maiden name. Her father owns a long-standing and respected obi shop, and her brother is the actor Saito Ryuji.
Saito is well known in Japan for being a member of The Church of Jesus Christ of Latter-day Saints, as she refused to work on Sundays. Additionally, in the 1986 film Koisuru Onnatachi, Saito used a fake cigarette used for asthma patients due to her LDS beliefs, which forbid the use of tobacco, including smoking.
