I've found a ton of second-rate Japanese martial arts dictionaries/glossaries online, but nothing that is accurate and comprehensive and which has both romaji and kanji (kana would also be nice). Anybody know if such a thing exists and, if so, where? I'm looking for something academic or at least quasi-academic, put together by someone who is fluent in Japanese as well as being proficient and experienced in the Japanese martial arts (as opposed to the dime-a-dozen ones every dojo's webpage has, most which are full of errors). Again, having the kanji and being specific to just the martial arts is critical.
Towards this goal, the closest thing I've found is this Japanese Martial Arts Character Dictionary. Assuming I can't find anything online and hence free, anybody know if this is worth the $60 (and even legit!)?
Thanks in advance.
