This is compiled collection of common Japanese SFXes (sound effects or onomatopoeia).
This collection mostly uses Romaji transliterations. The original version was compiled by for general public use but modified later for project-use. Some SFXs may be used in combination with other SFXs; some SFXs, or combinations thereof, may be written separately for emphasis within the same panel (example: do- ki-, ドッキッ ), but can be considered as part of the same action. Because of this, many SFXs can have multiple meanings and are dependent on the action drawn, as well as one's interpretation of that action.
