IMAGICA Infos is producing a new “light anime” adaptation of Hiroto Ida’s Omae wa Mada Gunma o Shiranai (You Don’t Know Gunma Yet) manga, dubbed Omae wa Mada Gunma o Shiranai ~Reiwa-ban~ (You Don’t Know Gunma Yet ~Reiwa Version~). The new You Don’t Know Gunma Yet ~Reiwa Version~ anime premieres in January 2026 on SKY PerfecTV!’s Tetsudō Channel.
As a light anime, You Don’t Know Gunma Yet ~Reiwa Version~ features a more simple animation style, which reduces production time and costs.
Ida launched the manga series on Shinchosha’s Kurage Bunch website in October 2013, and the series ended in May 2019. 11 compiled book volumes were released by Shinchosha. A 12-episode anime short series premiered in April 2018, and Crunchyroll streamed the series with English subs as it aired in Japan.
Lastly, here’s an overview of the anime series, via Crunchyroll:
Kamitsuki ends up having to move from Chiba Prefecture to Gunma Prefecture. He decides to do a little bit of research about Gunma on his way over, and everything he finds out is terrifying! For example, “The world’s only remaining unexplored area,” and “Make sure you take all your best equipment.” What kind of place is Gunma? What kinds of things are going to happen to him while he’s there? The Gunma-born author brings you the real truth about Gunma in this series.
