Life (Gen Hoshino song)

"Life" (Japanese: 生命体, Hepburn: Seimeitai, lit. 'Lifeform') is a song by Japanese singer-songwriter and musician Gen Hoshino from his sixth studio album, Gen (2025). Speedstar Records released the song as a digital-exclusive single on August 14, 2023, and later re-released it as a CD single with "Why" on December 27, 2023. Used as the theme song for TBS Television's broadcast of the 2022 Asian Games and 2023 World Athletics Championships, "Life" was written and produced by Hoshino, who co-arranged it with Mabanua. A fast-paced, piano and drum-driven rock and R&B song with elements of gospel, its lyrics interpret the mentality of athletes when competing in sports. Background vocals are performed with singer Ua.

"Life" was received positively by music critics in Japan, who praised its composition; some also found depth within the lyrics. Upon release, the song debuted at numbers 7 and 44 on the Billboard Japan Hot 100 and Oricon Combined Singles Charts, respectively. It topped the digital download component charts of both publications and was the most-aired song on Japanese radio within the week of release. The music video, directed by GroupN, features footage of Hoshino singing, interlayed with scenes of various people living their lives. The song was promoted on music television shows, including the 74th NHK Kōhaku Uta Gassen on New Year's Eve 2023.
