The Kobokushi (虎撲子? "Tiger Beating Child"), also known informally as the "Palm", is one of Yun's special attacks, introduced in the Street Fighter III series. The name is based on some of the idioms revolving around tigers and lions.

Yang used this move in the original Street Fighter III, until he replaced it with a variation of his own called Byakko Soshoda from 2nd Impact onwards.

Street Fighter III series Arcade Stick QCB + Arcade Button Punch (Arcade-Button-2xPunch or Arcade Button Punch x3 to feint)
Super Street Fighter IV: Arcade Edition
Ultra Street Fighter IV
Arcade Stick QCB + Sf3 punch medium or Arcade-Button-HPunch (Sf3 punch light version to feint)


Executed by performing a quarter-circle backward motion and pressing punch, Yun performs a simple but devastating two-handed pushing motion palmstrike at around abdomen level, accompanied with a stomp with his leading foot, which can knock the opponent to the other side of the screen. The move is similar to his younger brother's Byakko Soshoda, but with a shorter range due to Yun's partially bent arms (unlike Yang's fully extended arms).

The speed and damage are determined by the punch button used: light punch version has the fastest execution but least damage; heavy punch version has the slowest execution but most damage; and medium punch version is halfway between the two.

Street Fighter III seriesEdit

Like Kobokushi, it has no EX version. Instead, pressing more than one punch button will perform a feint; Yang will draw back as if to perform the attack but actually does not.

Super Street Fighter IV: Arcade EditionEdit

As with Byakko Soshoda, the feint is now mapped to the light punch button, while the medium punch (fastest execution but least damage) and heavy punch (slowest execution but most damage) versions perform as usual, and are capable of stopping fireballs. Also note worth, in the Street Fighter IV series, the Kobokushi's quarte-circle backward motion remains the same, unlike Byakko Soshoda's motion changed to quarter-circle forward. It should be noted that all variations of this attack are projectile and not strike hitboxes.

The EX Special version introduced in the same game has virtually no startup time and causes an opponent struck by it to be knocked against the edge of the screen and bounce off it, allowing for juggles.


Despite its slow startup, if timed correctly, the attack is extremely powerful and useful as a frame trap tool, and its hitbox is such that it can beat out other high-priority moves. The feint, besides stopping projectiles, is also good for baiting counters and parries early, or forcing opponents into dropping their guard by mistake.

However, the move requires Yun to be slightly closer, which can present a risk of counters. Still, it inflicts slightly more damage to reward the risk.


  • Akira Yuuki of the Virtua Fighter series has an altered variant of both this move and Yang's version, named the Koboku (虎撲, "Tiger Beating").
  • Yang uses this animation as his ending part for his punch Target Combo. Conversely, Yun ends his punch Target Combo with the Byakko Soshouda.
  • This attack is similar to Chun-Li's Hakkei as a special command.
