Japanese Crash is an alternative version of Crash, optimized for Japanese audiences.
On almost every Japanese version of the Crash games, Japanese Crash appears on almost every cover.
There is a code to unlock the Japanese Crash skin on the PS2 version of Crash Tag Team Racing. On the start screen, hold L1 and R1 and press Square, Circle, Square, Circle. If done correctly the player will hear a chime. The skin can be available for either Adventure Mode or Multiplayer mode, but when players enter the code, they will find the normal Crash which they are trying to race in Adventure Mode will have no pupils.
Crash has the looks of Japanese Crash in all versions of this game.
