I'm looking for a cheap secondhand character dictionary in Japan but:
I don't know if there is one or more kind of these, and I don't know what they are called.
Two I saw had these on their spines, but I don't know if they are titles or types of dictionary:
Tsuyoshi Ito suggests this term in a comment:
Is there more than one kind of character dictionary? What are the various kinds called? (Please supply romaji or at least kana too)
I do not need to know about general Japanese or translating dictionaries, just the ones that focus on kanji.
