SixTONES (ストーンズ, stylized as SixTONES and pronounced "Stones") is a Japanese idol boy band formed by Johnny & Associates in 2015. The group first developed as part of Johnny & Associates' pre-debut trainee unit, Johnny's Jr., where its lineup and identity took shape before their official launch. SixTONES made its official debut on 22 January 2020, moving from a trainee act to a fully launched group with a clear six-member structure.
As a six-member idol group, SixTONES is often searched by both name and member, and that lineup has remained central to how the group is recognized. Yugo Koichi serves as leader, alongside Taiga Kyomoto, Juri Tanaka, Hokuto Matsumura, Jesse, and Shintaro Morimoto. In anime music, SixTONES has also maintained a visible profile: in 2025, the group released the opening-song music video for WIND BREAKER Season 2, adding to the attention they have received from anime fans looking up their songs and members. Their history in Johnny's Jr., consistent core lineup, and 2020 debut have made SixTONES a familiar name in Japanese idol music and anime-related searches.
