In You Don’t Know Gunma Yet, Mamiya plays Nori Kamitsuki, a high school student who transfers from Chiba Prefecture to Gunma Prefecture, only to be blind-sided by the sheer number of cultural differences in his new home.
Actor Shotaro Mamiya will star as the lead character in a live-action film and a live-action TV series based on You Don’t Know Gunma Yet (known in Japan as Omae wa Mada Gunma wo Shiranai), a humorous web-comic by Hirota Ida about a high school boy who experiences extreme culture shock when he moves to Gunma Prefecture.
The original You Don’t Know Gunma Yet manga is serialized in Shinchosha’s Kurage Bunch digital manga magazine.
