Show HN: I'm making an open-source platform for learning Japanese

I agree with you, but Anki is a generalized flashcard SRS memorization tool, not specifically made for learning Japanese, so it's not within my area of critique; I'm thinking of apps similar to Duolingo. It works extremely well because it helps you memorize very efficiently. One of the few applications that will indeed boost your learning by a lot. Anything requiring manual input rather than a simple Again or Good button choice tends to be worse. Any Anki deck requiring manual input as an answer should not be used.

Great start! I like the aesthetic and focus on a single language. Most of all, making it open source and just getting it out there!

I'd love to collaborate, but I think we've got to look at overall concept first. There's a lot of information on the screen and it's not really clear how the learner journeys through. Greatly reducing the amount of info on the screen at once, focusing learner's attention on a single path would be helpful.

There's many theories of language acquisition, but I think Krashen is most on-point: we learn through comprehensible input. New vocabulary really needs to be encountered in context of meaningful sentences that are understandable to the learner. Further, when training, production with spaced repetition is really the most effective strategy.

I'd love to see there be a really great free learning tool that brings a pedagogically sound approach to Japanese learners!

And maybe talk to people in Japanese? And do some writing? Not just passive consumption.

Some constructive criticism:

1. For picking the kana answers, using the keyboard key is better than numbers. When you actually type an え, you type 'e', so it's a useful mapping to learn in terms of how IME works.

2. For vocabulary, there should be an option to turn off romaji in favor of kana only. No explanation needed I think

3. The vocab quiz, between kanji and just an english word, is an anti-pattern in my opinion. Recognizing the meaning if vocab in a full japanese sentence is a much better basic quiz, especially since not all words have 1-1 mappings. It also doesn't quiz on the reading, which seems weird. Also, an easy example of something confusing there is that 辺 is 'area', but if I see 'area' my first thought is 面積 (like the area of a triangle), while 辺 would be edge in that context... and my second thought is 地域, like "the area of the country I grew up in". I think 辺 is maybe 4th or 5th for 'area', and that's just because 'area' is a broad english word. My point is, quizzing vocab -> english word, without reading, without an example sentence, is a recipe to confuse learner's brains.

4. Same complaints as vocab for the kanji quiz, but moreso since kanji's meaning is more abstract.

The beautiful aesthetic and open-source way to learn Japanese is to make Anki flash cards, and customize the cards using html (which it already supports).

This entire site could have been anki decks, and then it would have had spaced repetition for free, and users could even more easily edit things to suit themselves ad add to it.

This is actually NOT recommended for a beginner.

Writing and speaking are effective at establishing long term memories, it's why we do it for other things, but a language learning beginner has no idea if what they're writing makes sense or if there's any subtle mistakes in how they're pronouncing words or how they're putting them together, etc.

Language learning experts don't recommend you start speaking/writing unless you have a coach or have reached an intermediate level so that you can discern when something sounds native or not. That way you can self evaluate with recordings, etc.

It is an effective tool for learning, but for self-learning you're gonna be shooting yourself in the foot long term. You should only do it if you have, say, a partner that speaks the language and doesn't mind correcting you all the time.

For Japanese I recommend that you do learn how to write kana/kanji from the start, and even some vocab if you want. But stop there. Don't write sentences, don't try to talk to japanese people on those apps/discord etc. and wait until you're at an intermediate level to do it, otherwise you'll form some very bad habits that are very hard to undo.
