Fujitsu Nextera Lab announced today (October 2, 2025) the official launch of the game “Tonde Saitama ~World Saitamaization Project~” on GMO Media’s gaming platform “Gesoten by GMO.”
This title is based on the live-action comedy film of the same name, adapted from the manga “Tonde Saitama” by Moyo Mineo.
The movie was released in February 2019 and earned ¥3.76 billion at the box office. It won Best Director, Best Screenplay, and Best Editing awards at the 43rd Japan Academy Prizes. A sequel titled “Tonde Saitama ~With Love from Lake Biwa~” premiered in November 2023.
The story takes place in a fictional Japan where severe discrimination exists based on hometown or residential district. Saitama residents endure harsh persecution from Tokyoites—being denied entry to Tokyo without proper travel documents and even forcibly deported.
One day, an exceptionally handsome and academically and athletically gifted boy named Asami Rei transfers into the prestigious White Phoenix Hall Academy in Tokyo. The academy’s top-ranking student, White Phoenix Hall Momomi, falls for him—though his true identity is that of a “secret Saitama native” who infiltrated the school to abolish the document system.
The game portrays regional conflicts across Kanto—including Gunma, Kanagawa, Tochigi, and Ibaraki—with humorous jabs at local stereotypes.

In the game, players join forces with characters from the film to carry out the “World Saitamaization Project”—transforming all regional specialties across Japan into Saitama products. Collect newly acquired Saitama specialties through local rivalries, and enjoy numerous “Saitama vs. Other Prefectures” local roast battles. Expect familiar regional jokes like: “The probability of miso peanuts appearing in Chiba’s school lunches is just too high!”
