The announcement was revealed via a surprise projection mapping event at Zojoji Temple in Tokyo on August 17. The event, which was originally framed as a music video recording session, reportedly surprised the group members themselves. During the reveal, the group performed ‘KEY 2 LIGHT’, the theme song for a TV Tokyo table tennis program. Formed in February 2025 following a reorganization of junior groups including Bi Shonen, HiHi Jets, and 7 MEN Samurai, the group consists of Mizuki Inoue, Taisho Iwasaki, Reia Nakamura, Taiko Sasaki, and Soya Igari. Some members have been active as junior performers for over a decade, with some reaching 17 years of experience. During the final day of their ‘KEY TO LIT Arena Tour 2026 NEO CLASSICS’ at Ariake Arena on August 23, the group held a press conference. Addressing approximately 15,000 fans, the members expressed their ambition to become the ‘greatest masterpiece’ in their agency’s history, with Taisho Iwasaki specifically setting a goal to perform at a dome stadium within three years. The tour is expected to reach approximately 238,000 people across 21 performances in five cities. ## Timeline ### 2026-08-27: KEY TO LIT announces winter CD debut with Universal Music The STARTO ENTERTAINMENT junior unit KEY TO LIT will make its CD debut this winter with Universal Music following a surprise announcement and a successful arena tour. 2 sources. https://clstr.news/cluster/key-to-lit-announces-winter-cd-debut-with-universal-music-1 ### 2026-08-23: KEY TO LIT announces winter CD debut with Universal Music Junior idol group KEY TO LIT has announced their winter CD debut with Universal Music, aiming to become a legendary act after over a decade of training. 3 sources. https://clstr.news/cluster/key-to-lit-announces-winter-cd-debut-with-universal-music ### 2026-08-17: KEY TO LIT announces surprise CD debut this winter STARTO ENTERTAINMENT's idol group KEY TO LIT announced a surprise CD debut with Universal Music this winter during a fan event at Zojoji Temple in Tokyo. 6 sources. https://clstr.news/cluster/key-to-lit-announces-winter-cd-debut --- Cite as: KEY TO LIT CD debut announcement and tour details.
