It's a pity though that Namco don't release Taiko no Tatsujin outside of Japan, while there are lots of international Taiko fans out there. The reason? Is it licensing? Network issues? Translation? Profit-oriented? Or perhaps... The experience they had after releasing Taiko Drum Master for PS2? Who knows.
If you want to see the latest arcade version in your country, you can help them by signing up the petition here. They will then send a physical letter as well as the result of the petition straight to Bandai Namco Games. Let's convince Namco to send Taiko internationally, together!
