Free tools for learning Japanese
You can get a long way learning Japanese without spending a cent. The catch is that free resources are scattered, uneven in quality, and easy to collect without ever actually using. This is an honest guide to the kinds of free tools that are genuinely worth your time, and, more importantly, how to fit them together into a routine you will keep.
Start with the fundamentals, kana
Before anything else, learn hiragana and katakana. They are the two phonetic scripts, there are only a few dozen characters each, and almost everything else you do in Japanese assumes you know them. A few days of focused practice here saves you months of friction later, because you stop depending on romanized text that holds your pronunciation and reading back.
Any simple flashcard-style drill works for kana. The important thing is to practice recall, seeing the character and producing the sound, rather than just reading charts.
A dictionary you will actually keep open
The single most useful free tool for a Japanese learner is a good dictionary. Community-built dictionaries let you look up words by meaning, reading, or kanji, show example sentences, and break words into their component characters. You will reach for one constantly, while reading, while studying, and while puzzling out a sign in a photo. Pick one, learn its search shortcuts, and make it a habit.
When I was learning, I leaned on all sorts of general language apps, Duolingo among them, and they genuinely helped me build momentum and a daily habit. Where I struggled was learning vocabulary quickly, especially kanji. I kept looking for a faster, more focused way to drill characters, and a quiz-style approach like the one in Kanji Monster turned out to fit the way my memory works far better than anything else I tried.
Drill kanji a little, every day
Kanji are where a lot of learners stall, usually because they try to absorb too many at once and then burn out. The reliable approach is the opposite, a small number of characters, practiced actively, every day. A focused drill that quizzes you and brings back the ones you miss will take you further than any amount of passively re-reading a kanji chart.
This is exactly the gap Kanji Monster was built to fill, with short, free, browser-based kanji practice and no signup. If you want the reasoning behind why daily repetition works so well, I wrote about it in why repetition works for memorizing kanji.
Grammar, one clear explainer rather than ten
There are excellent free grammar guides online that take you from your first sentence through fairly advanced structures. The mistake is collecting five of them and bouncing between them. Pick one guide that explains things in a way that clicks for you and work through it in order. Consistency of source matters more than finding the “best” one.
One thing that helped me with grammar was to stop treating it as a list of rules to memorize. A grammar point is really a sense of how something is used and what nuance it carries, and that sinks in far better from seeing plenty of example sentences than from drilling the rule in isolation. So I would read a short explanation once, then spend most of my time on real examples until the pattern started to feel natural.
Reading, start absurdly small
Reading is where your vocabulary and grammar turn into real comprehension, but most learners wait far too long to start because they think they need to be “ready.” You don't. Begin with graded readers, simple news written for learners, or short passages with furigana. The goal at first isn't to understand everything. It is to get comfortable seeing the language in the wild and looking things up as you go.
Listening, make it ambient
Free listening material is abundant, including podcasts for learners, slow-speech news, and endless video with subtitles. Early on, you won't catch much, and that is fine. Regular exposure trains your ear to the rhythm and sounds of the language long before you can parse full sentences. Fifteen minutes on a commute counts.
How to fit it together
The tools matter less than the routine. Here is a simple weekly rhythm that works.
- Every day. A few minutes of kanji drilling and a quick vocabulary review.
- A few times a week. A grammar lesson and a short reading passage.
- Whenever you can. Passive listening in the background.
The routine that worked best for me had three simple stages. First I would learn a batch of new words. Then I would study example sentences built around those words so I could see them in context. And finally, to lock them in, I would try to write my own sentences using them. You memorize a word, you see it used, and then you produce it yourself. That last step of actually composing something is what turned words I merely recognized into words I could use.
Notice that this is mostly small, daily actions, not marathon sessions. That is deliberate. The learners who succeed aren't the ones with the best resources. They are the ones who show up in small amounts, consistently, over a long time.
The honest bottom line
You don't need to spend money to learn Japanese, and you don't need a dozen apps. You need a good dictionary, one grammar guide, a daily kanji habit, and something to read and listen to, used consistently. Keep the toolkit small so you spend your energy studying instead of managing tools. That philosophy is the whole reason Omnu exists, and you can see the current lineup of free tools on the home page.
