Information

Tenda Games Co., Ltd. (Headquarters: Toshima-ku, Tokyo; President and CEO: Ryohei Asaoka; hereinafter “TENDA Games”) is supporting the development of the “Jomo Karuta” browser game, a Gunma Prefecture karuta game currently available on the “Yamada Game” gaming platform operated by Yamada Denki Co., Ltd. (Headquarters: Takasaki City, Gunma Prefecture; President and CEO: Takahiro Sano; hereinafter “Yamada Denki”).

We have recorded the voiceovers for reading the cards and navigation for the game, featuring FM Gunma radio personality Satoshi Naito and announcer Madoka Ichikawa. These voiceovers are scheduled to be released as paid add-on voices from mid-May onwards. However, prior to the release, they will be made available for free for a limited time from March 23, 2026, until the game’s launch. Please take this opportunity to enjoy their unique voiceovers of reading the Jomo Karuta, which differ from their radio talk.

The local card game “Jomo Karuta,” beloved by the people of Gunma Prefecture, has seen a decline in play in recent years. This project focuses on “Jomo Karuta,” a joint project between Gunma Prefecture and Yamada Game, with Tenda Games involved in development. This valuable educational material, offering insights into Gunma’s history, culture, and geography, has been digitized and presented as an easy-to-play browser game, making it accessible to younger generations.
