This book introduces history of sushi, history of sushi and simple ways to make sushi. とても面白いです！I learned how to eat sushi in a correct way. Although I eat a lot of sushi and love sushi, I didn’t know how to eat it appropriately until I read this book.
Vocabulary and sentence structures are a little difficult for Japanese beginners, because it contains a lot of kanji (while it is easy to understand for Chinese speakers). But I think 日本語一年生 can understand the content with these cute pictures.
I didn’t intend to read this whole thing, since it’s sort of a glossary of Japanese onomatopoeia, and very long. But it consists of little comics explaining the onomatopoeia, which I found to be fairly easy to understand – they use a lot of familiar vocab, and almost entirely familiar grammars, and they’re very simple. Plus, the book provides romaji and a translation, so you can check yourself as you go! I would definitely recommend this to 2nd years. (Plus, the pun in the title is just. So enticing.)
