A small assortment of random Japanese onomatopoeias, for you:
The dog says: wanwan
The cat says: nyaonyao
The baby chick says: piyopiyo
The rooster says: kokekokko
The gleaming, sparkling object says: pikapika
The knock on the door says: tonton
The door bell says: pinpon!
The crunchy snack says: sakusaku
The empty stomach says: pekopeko
The contented snorer says: guuguu
The rapidly beating heart says: dokidoki
The knocking knees say: gakugaku
The sneezer says: hakushon!
In Japanese, onomatopoeias are written in katakana and there is no equivalent for “bless you” or “gesundheit.” Hakushon is only met with silence.
