Koresawa (コレサワ)

Koresawa (コレサワ) is a Japanese singer-songwriter from Settsu, Osaka Prefecture. Born 是澤寿美 on May 19, 1992, she debuted in 2011 and works mainly in j-pop. Her songs are associated with candid, conversational lyrics, memorable melodies, and an intimate vocal style, often centered on everyday relationships and small, specific moments. After appearing at SUMMER SONIC in 2012, she released the independent record 『憂鬱も愛して』 through RECO RECORDS on March 5, 2014. Her first nationally distributed EP, 『君のバンド』, followed on April 29, 2015. She then provided “シュシュ” for TV Tokyo’s 『廃墟の休日』, released the EPs 『女子、ジョーキョー。』 and 『ジエイポップ』, and made her major-label debut on Nippon Crown with the album 『コレカラー』 on August 9, 2017. Outside live performances, she generally does not show her face in magazine, television, or radio appearances. Instead, she is represented visually by the bear-girl character 「れ子ちゃん」 created by ウチボリシンペ. In 2024, “君がおじいちゃんあたしがおばあちゃん” was used as the theme song for the television anime 『じいさんばあさん若返る』. The lyrics she wrote for 超ときめき♡宣伝部’s “最上級にかわいいの!” earned the 作詩賞 at the 66th Japan Record Awards. She also performed “Zutto 1-ban ni Shite ne (ずっと１番にしてね),” the ending theme of Class de 2 banme ni Kawaii Onnanoko to Tomodachi ni Natta / 『クラスで2番目に可愛い女の子と友だちになった』. In 2026, she announced her fifth mini album PINK BEARS, an eight-track release unveiled with new artwork, and became a new lecturer on TOKYO FM’s SCHOOL OF LOCK!.
