This online dictionary is “based off the Kenkyusha dictionaries. The English entries are good, but the Japanese entries are superb, breaking the word down into all of its potential meanings(including peripheral or metaphorical ones), cross-linking most of the compounds in its definition to other entries and in many cases giving example sentences. It is definitely more useful for intermediate and advanced students… It took a bit of effort to get used to reading the entries in Japanese, but after looking up a few lower level words, you can easily get a feel for how things tend to work. Cannot recommend enough.” [annotation from Tanuki, commenting on Tofugu.com]
