We already knew Taiko no Tatsujin's characters are pretty darn cute from playing the games, but this clay anime series, officially produced by Namco, makes sure we'll never forget it. Though it's supposed to be a show for children -- it originally aired on Japan's Kids Station channel, if that's any indication -- we've found ourselves totally drawn into the adventures of Wada Don, Wada Katsu, and their clay friends.
A total of 26 episodes were put out over two seasons in 2005-2006, and the first seven are subtitled and available to watch on Youtube. Like the clip above, each Taiko No Tatsujin Clay Anime episode is only four minutes long, so you could feasibly watch the entire collection of translated videos in the time it takes you to watch a single episode of a much less interesting anime.
On the topic of Drum Master, Siliconera has an excellent preview and walkthrough of Taiko no Tatsujin: 7 Islands' Adventure, which shipped to stores in Japan just last week. Combine that with these menu translations, and you've got nothing stopping you from importing the rhythm game!
