Koresawa (コレサワ)

Koresawa (コレサワ) is a Japanese singer-songwriter whose real name is 是澤寿美, born on May 19, 1992. Working in J-pop and related pop styles, she is known for songs built around candid, conversational lyrics, memorable melodies, and a direct emotional perspective that focuses on everyday relationships and small, specific moments. Her music often blends J-pop with acoustic-leaning arrangements and an intimate vocal approach, giving her catalog a warm, hook-driven quality without depending on heavy production. That songwriter-first style has helped define her identity in contemporary Japanese pop, where the writing and melody usually carry the emotional weight. One of the songs many listeners associate with Koresawa is "Zutto 1-ban ni shite ne," which reflects her ability to turn plainspoken feeling into a catchy, memorable pop song. Koresawa is associated with Nippon Crown, and her career has continued to connect with anime audiences as well. In 2026, she announced her fifth mini album, PINK BEARS, with new artwork and a planned eight-track release, and she also revealed the ending theme for the TV anime 『クラスで2番目に可愛い女の子と友だちになった』. Around the same period, she was also named a new lecturer on TOKYO FM’s SCHOOL OF LOCK!, adding another high-profile chapter to her public profile. For listeners searching for Koresawa or "Zutto 1-ban ni shite ne," her work remains a strong example of modern Japanese pop built around emotional detail, polished melodies, and a distinct singer-songwriter identity.
