Original 09/25/18 at 5:10 a.m.: Fitness Boxing, the June-announced boxing game developed by Imagineer for Switch, will launch on December 20 in Japan, the latest issue of Weekly Famitsu reveals.

Nintendo will simultaneously distribute Fitness Boxing outside of Japan, according to Imagineer, but an exact release date was not announced.

Here is an overview of the game, via our previous coverage:

Fitness Boxing is described as a full-blown boxing program arranged by the Fit Boxing Japan foundation to be experienced at home on Switch for the purpose of easy and effective boxing training. By holding both Joy-Cons in your hands and following along with the in-game instructor, you will be able to enjoy a refreshing exercise with the sense of playing a video game.

Thanks, Famitsu.

(Editor’s Note: In Japan, Fitness Boxing is called Fit Boxing.)

Update 09/26/18 at 12:02 a.m.: Fitness Boxing will cost 5,800 yen. Its genre is listed as “rhythm game.”

Players will exercise by performing boxing movements with the Joy-Cons. The game will have a “My Data” feature that keeps track of exercise time and calories burned. Six instructors will support the player. You can also customize them to your liking. Several voice actor options are being prepared, including Saori Hayami, Atsuko Tanaka, Sumire Uesaka, Ami Koshimizu, Yuichi Nakamura, and Akio Ootsuka.

Thanks, Ryokutya2089.
