Although beloved by Gunma residents, the local karuta “Jomo Karuta” has seen a decline in play in recent years. This time, focusing on “Jomo Karuta,” Tenda Games is involved in the development of this collaborative project between Gunma Prefecture and Yamada Game. This valuable educational material for learning about Gunma Prefecture’s history, culture, and geography has been digitized into an easy-to-play browser game, accessible to younger generations.
