Onomatopia: An Illustrated Bilingual Guide to Japanese Onomatopoeia by Terry & Simon

Onomatopia: An Illustrated Bilingual Guide to Japanese Onomatopoeia (テリーとサイモンのオノマトピア) is an illustrated bilingual (Japanese-English) guide to Japanese onomatopoeia.

Created by Terry Johnson and Simon together with a Tokyo Shoseki team, it teaches onomatopoeia (オノマトペ) —those expressions so characteristic of Japanese— through illustrations that let you grasp each word at a glance. Every term appears in Japanese and in English, with usage examples.

Recommended level: Beginner to intermediate. The illustrations and the two languages (Japanese and English) make it approachable from basic levels, while the breadth of onomatopoeia is useful up to an intermediate level.

Useful features for learning: each onomatopoeia explained with an illustration and its English translation, with real usage examples.
