Two 3DS Taiko no Tatsujin RPG games are actually being localized. During the August 26, 2020 Nintendo Direct Mini, Bandai Namco revealed Taiko no Tatsujin: Rhythmic Adventure Pack for the Nintendo Switch. This means, for the first time, Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken and Taiko no Tatsujin Dokodon! Mystery Adventure. They originally appeared in Japan in 2014 and 2016, respectively. It will launch in Winter 2020.
In both games, Don and Katsu are off to save the world and help people by fighting enemies with the power of music. Each fight involves playing through a song on the drums, like you would in a normal Taiko no Tatsujin game. You eventually recruit a party of monsters to fight back. You can also play through 130 songs in the normal rhythm game mode. Six new songs will be available in this collection, with one being Demon Slayer’s “Gurenge.”
In Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken, which is referred to here as Rhythmic Adventure 1, Don works alongside Tocky, a rabbit who protects history, to save Ticky. This means traveling through time to find his kidnapper, Professor Timedyne. Taiko no Tatsujin Dokodon! Mystery Adventure is referred to as Rhythmic Adventure 2 and has Don and Katsu trying to find Ooparts stolen from The Hexagria Magical Society and keep them from falling into the hands of people who would misuse them.
Taiko no Tatsujin: Rhythmic Adventure Pack will come to the Nintendo Switch in Winter 2020. Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken and Taiko no Tatsujin Dokodon! Mystery Adventure are available on the Nintendo 3DS in Japan.
