One or Eight INC.

One or Eight INC. (株式会社ワンオアエイト) is a Japanese entertainment company headquartered in Chiyoda, Tokyo. It operates across three business domains: software planning, development, publishing and operation; education support; and virtual talent management. The company was founded in April 2012 by Issei Komura, a founding member of the game developer Imageepoch who left that company after a management dispute. One or Eight began in difficult circumstances, with Komura developing games on a MacBook in a park after the company lost its office due to funding shortages. A loan from the Japan Finance Corporation, arranged through an accountant, helped the company survive. An early contract from NHN Japan for Strike Witches 2: Bonds of the Blue Sky allowed it to secure an office, and later ArtDink introduced it to basement space in the Wise Building in Tsukishima. In October 2015, the development division was transferred to Studio One or Eight, leaving One or Eight as a publisher focused on sales and distribution. The company released its own title EARTH WARS on PlayStation 4 and Xbox One in September 2015, and has since worked on contract development for major titles including Fate/Grand Order (graphics support) and Final Fantasy VII Remake (programming and level planning). It also runs the virtual talent agency and YouTube channel Icchan Neru. In September 2023, Studio One or Eight absorbed the first-generation One or Eight and changed its name to One or Eight INC. (second generation). As of April 2025, the company had 74 employees. Its clients include Sony Interactive Entertainment, Nintendo, Valve Corporation, GREE, Lasengle, Akatsuki, Square Enix, Drecom, Pokelabo, and Mixi. It is a full member of CESA and CERO, and a member of CG-ARTS.

One or Eight INC. was founded in April 2012 by Issei Komura, a founding member of the game developer Imageepoch. Komura left Imageepoch after a conflict with its management. The early years were difficult: due to a lack of funds, the company cancelled its office lease and was on the verge of bankruptcy. However, an accounting firm with which Komura had a relationship introduced him to a person at the Japan Finance Corporation, and One or Eight obtained a loan from that institution. With no office, Komura began developing games using a MacBook in a park. This marked the beginning of One or Eight. The company then received a development contract from NHN Japan for Strike Witches 2: Bonds of the Blue Sky, which allowed it to finally secure an office, though it had to vacate it when the project ended. Around this time, employees of Imageepoch, which was facing its own management crisis, began asking to join One or Eight. ArtDink then offered the company a sublease in the basement of the Wise Building in Tsukishima, where ArtDink's headquarters were also located, and One or Eight moved there. In October 2015, the development division was transferred to a new company, Studio One or Eight, and One or Eight became a publisher handling only sales and distribution. In September 2015, the company released its own title EARTH WARS on PlayStation 4 and Xbox One. It subsequently undertook contract development for titles such as Fate/Grand Order (graphics support) from TYPE-MOON and Final Fantasy VII Remake (programming and level planning) from Square Enix. In January 2018, it released the Nintendo Switch version of EARTH WARS. On September 1, 2023, Studio One or Eight absorbed the first-generation One or Eight and simultaneously changed its trade name to One or Eight INC. (second generation). The company also operates a virtual talent management business under the YouTube channel name 'Icchan Neru'. As of April 2025, it had 74 employees.
