For any Japanese learners/speakers who are also tackling Korean, my Korean dictionary app, Dusajeon, includes Korean hanja and information is presented in a way that would feel familiar to Japanese learners. You can search the dictionary using Korean or English, but you can also view definitions in Japanese and I think it’s a nice tool for those who wish to learn both languages, or even just interested in learning Korean with Chinese characters!
