Sphere Tickets

Sphere is a celebrated four-member seiyuu idol unit formed by voice actresses Haruka Tomatsu, Minako Kotobuki, Ayahi Takagaki, and Aki Toyosaki in 2009, with Aki Toyosaki joining Sphere’s public activities in that same year. The group quickly established itself in the J-pop scene with anime and game soundtrack ties, debuting in 2009 with the song Future Stream, which served as the Hatsukoi Limited anime opening. Notably, Sphere achieved a milestone by performing at Nippon Budokan within roughly 1 year and 9 months of formation, a standout achievement for a seiyuu idol group. Their music blends catchy melodies with vibrant energy, making them a favorite among anime fans and J-pop listeners alike. Below you’ll find a concise look at their biography, discography highlights, and upcoming tour information.

Sphere’s core sound centers on memorable hooks, lush vocal harmonies, and frequent ties to anime and game soundtracks. Their six studio albums—A.T.M.O.S.P.H.E.R.E, Spring is here, Third Planet, 4 colors for you, ISM, and 10s—showcase versatility across pop, electronic, and indie influences. A 2015 compilation, Sphere's 5th Fan Select Best Album, highlights fan-favorite tracks.
