Taiko no Tatsujin: Atsumete - Tomodachi Daisakusen! is the third Taiko videogame for the Wii U home console, and the second console game to be released in occasion of the 15th Anniversary of the Taiko no Tatsujin franchise; as such, the Game + Tatacon bundle of this title also includes a set of promotional goods related to the anniversary celebrations.

This installment inherits the signature multiplayer modes from the previous Wii U games (Baton Pass from Wii U Version and Intro Don! from Tokumori), with the addition of the new 'Buddy Attack' single-player mode, in which Taiko sibling Kat-Chan tries to become a popular star by befriending wild animals from the streets with music. Content unlocking through the Mekadon Gacha and DLC supports make their return, as well as the coming of Nintendo-exclusive features to the game like Miiverse support and, for the first time ever, compatibility with Nintendo's Amiibo figurines.

One day, the Wada family (including their neighbour Hana) arrived at the airport to catch up with the air flight to Hawaii for vacation.

Unfortunately, Katsu, the youngest of the Taiko drum duo, slips on a banana peel and crashes into a wall, knocking him out unconscious in the process. As he wakes up, Katsu finds out that he missed the flight and Don and the others have already left for Hawaii without him.

He thinks forward about what can he do while no one is at home as he feels lonely before he settled on something: to become the top popularity star of the (singular) street.

How will Katsu do to accomplish this? By befriends the animals around the street!
