The Foundation of Onion

Onion Games was founded in 2012 by a group of veteran game developers gone rogue, to take the independent game scene by storm! Director Yoshiro Kimura opened the studio following a career designing a number of cult classic games including the kissing adventure Chulip and gothic survival horror Rule of Rose, both for the PlayStation 2, as well as Little King's Story for the Nintendo Wii.

Joining him was pixel artist extraordinare Kurashima Kazuyuki, who cut his teeth doing character designs on Nintendo's SNES classic Super Mario RPG, before going on to collaborate with Kimura on games like the PlayStation's Moon: Remix RPG Adventure (often cited as one of the most charming and original games yet to be released overseas) and Little King's Story. He then again worked with Nintendo as the character designer behind the very strange and similarly delightful Legend of Zelda spin-off Freshly-Picked Tingle's Rosy Rupeeland, for the Nintendo DS.

Also part of the Onion crew are master game musicians like Hirofumi Taniguchi, who provided the soundtracks to a number of early Konami 16- and 32-bit hits before scoring games like Moon and the GameCube's Chibo-Robo!, as well as Keiichi Sugiyama, the composer behind a number of SEGA franchises including Sonic, Daytona, and even the <Area 1> music for Tetsuya Mizuguchi's groundbreaking musical shooter Rez.

Since its foundation, Onion Games has released the singularly bizarre mobile puzzle game Million Onion Hotel for iOS and Android, and the operatic shooting game Black Bird for Windows, Mac and the Nintendo Switch. Both recieved worldwide critical acclaim for their uniquely Onion Games design and aesthetic approach, and have cemented the company as one of the top Japanese indie studios.

The team are currently developing the soon-to-be-released Dandy Dungeon for the Nintendo Switch, just one of the many releases it has planned for 2019.
