Chart time! Here is how well Taiko games have performed in last year's top-selling games in Japan list, made once again by NeoGaf from a Media Create research.
Taiko Wii 5 is 23rd, Taiko 3DS 1 is 35th, Taiko Wii U is 105th (ouch), Taiko PSP DX is 175th and Taiko Wii 4 is 354th. Also there is this Taiko Risshiden V from Koei at the spot #574, but that surely isn't a Namco rhythm game xD
