Iai Giri (ゐあひ斬り Iai Giri?) is the 8th game in Rhythm Tengoku. In this game, The Wandering Samurai is protecting a town from Evil Demons wearing tengu masks by slicing them.



The player uses the A Button to quickly unsheathe, slice, and re-sheathe their sword in order to cut down enemies moving to the beat of the music. Fog eventually creeps in to obscure the player's vision of the enemies and forces them to use their sense of rhythm to best them. The more times the samurai succeeds in felling his enemies, the more intense his stance and hairstyle become.


  • A: Slice

Timing Notes

  • Hit: The samurai slices the enemy directly in half.
  • Barely: The samurai's sword smacks the enemy, causing it to tumble off the screen. His stance returns to the first one. A barely counts as a miss.
  • Miss: The enemy continues its path and hits the samurai, making him cry out in pain while flinging his entire body backward. His stance returns to the first one.

Rating Notes


  • "見物人のはなし" (The spectator's talk)

Try Again

  • "きほんが できてませんな。" (The basics are not down.)
  • "てきが見えないと ダメっぽい..." (Looks like it's no good when you can't see the enemy.)
  • "速いのが ニガテみたい..." (Looks like you're not good at the fast parts.)


  • "う~ん..." (Yeah...)
  • "まぁまぁ、 かな。" (OK, I guess?)
  • "とりあえず..." (Anyway...)
  • "よしと します。" (You did your best.)


  • "てきが見えなくても イイカンジ!" (Even when you can't see the enemy, you did well!)
  • "速いテンポが うまくとれてる!" (You got the fast tempo well!)
  • "スローが おみごと!" (The slow parts were perfect!)




  • The name of the game uses an old character,ゐ (wi?), that is rarely used in modern Japanese, where the game's name would be written "いあい斬り", meaning "killing an opponent by drawing one's sword." If read with the old spelling, it would be pronounced "Wiahi Giri".
    • This game lacks an official English name due to Rhythm Tengoku not being released outside of Japan. The closest would be the name of Samurai Slice in Rhythm Heaven, which is named Iai Giri Gaiden in Japanese.
  • This is one of a few games in Rhythm Tengoku that doesn’t have a practice.
  • The Wandering Samurai has returned in other games in the series.
