Reddit reviews Japanese Sentence Pattern Dictionary (Japanese Edition)

I have the Japanese edition (available on amazon.co.jp and amazon.com), and it's excellent. I'd encourage anyone working towards the N2 or higher to go for that version instead. The explanations are clear and concise in the same manner as the 新完全マスター series, and once above the intermediate level being able to understand and internalize explanations of Japanese given in Japanese becomes a crucial skill.

I haven't used it myself, but I have seen recommendations for 日本語文型辞典, which you can get from amazon.co.jp

If you want a Japanese book on Grammar, the 日本語文型辞典 should be the best bet, I doubt you will find it in a Book Off, though.

It covers a VERY wide range of grammatical topics, I'd say about every topic you'll find in the Dictionary of Basic/Intermediate/Advanced Japanese Grammar combined. Kanji in example sentences have furigana, but grammar explanations don't have them, so I don't know if you'll understand all the explanations, but with a bit of dictionary work it should be fine?

If you're willing to forego English buy still want furigana, this may be for you: https://www.amazon.co.jp/gp/aw/d/4874241549/

Back in the dark ages when I was learning Japanese, I picked this book up in Japan, and swore by it for a while:

It's similar to the DB(I/A)JG, but all in Japanese. I also liked the 新明解国語辞典, a J-J dictionary which has explanations that are more colloquial than the 広辞苑, which tends to be more ubiquitous and popular.

I would always encourage people to try to make the jump (or at least expose yourself) to native reference materials as quickly as possible (i.e. as soon as they begin to make sense to you), as (1) the explanations are invariably more detailed and (2) one of the things that will really help you "level up" in Japanese is being able to understand the language as a native speaker does, rather than in terms of English (or whatever your first language is).
