I'm not interested in Japanese, but for learning a language in general, i don't recommend Duolingo (don't know if the japanese course itself is bad). It's only good for vocabulary, but it's lacking in grammar.

I've heard good things of Anki (can vouch for, at least for latin, hebrew n ukrainian), Ringotan and Wanikani.

Anki is especially great, it's just flashcards so it can be for any language, even more than just languages. It works for latin, hebrew and ukrainian and they're all actually good.

But after all it's your choice, these are just recommendations. If duolingo works for you, then it works.

I find that it's pretty good, but I paid for premium so I don't know if the basic version is as good.

What I like most, is that you can practice the language you are learning with example scenarios, and get feedback from other users.

You also get stars for doing lessons and giving feedback to other users, which with the streak helps me do the lessons regularly. (There is a leaderboard too but I just ignore it.)
