Taiko No Tatsujin 10

The 10th arcade Taiko, released on July 2007. Another big step for the series, this version was the first one to have secret unlockable songs deep within the arcade software. They are unlocked by hitting the rims of the drum in a certain order after your coins are slotted in. The methods of unlocking secret songs would be placed on Namco's official Taiko blog (which was started together with Taiko 10 and DS1).

Not many other changes were made, except now, instead of 'Game Over', the arcade presents the message in full Japanese (it says 'おしまい　まだあそんだね！-oshimai, mada asonda ne! ' meaning 'The game has ended, come play again soon!') and an option is presented to people who still prefer to see the songs arranged by difficulty- just hit the left and right rims quickly one after the other at the song selection screen to switch orders. Plus, the tutorial is no longer forced onto players selecting Kantan, instead placing an option to open the tutorial right next to Kantan. You can skip it with 5 taps on the rim, and it disappears altogether if you open the Oni difficulty.
