Thirty days from no Japanese at all to reading a short paragraph unaided, about half an hour a day.
Japanese is written with two sets of 46 characters, each one standing for a syllable, plus a third set borrowed from Chinese, where one character stands for a meaning rather than a sound. The course teaches all of the first two and 42 of the third.
You also meet 57 grammar points, the patterns that hold the words together: saying what something is, asking about it, saying no, talking about yesterday, describing something, inviting someone. You can introduce yourself, thank someone, and ask them to say it again more slowly.
That is enough to read a paragraph and follow it without rebuilding it in English first.
One day opens per day. You cannot race ahead, because the gap between sessions is when the words settle.
Days 1 to 3 have no new characters. You read a real sentence on day 1, with its sounds printed in English letters above it. Hiragana, the first set of 46 characters, starts on day 4.
Hiragana is finished on day 11, a day of reading with no new grammar. Katakana, the second set of 46, starts on day 12. The week also covers saying you do not do something, talking about yesterday, and going places.
Katakana is finished on day 18. On day 19 the printed sounds come off for good. Day 21 starts kanji, the third set, borrowed from Chinese, where one character stands for a meaning rather than a sound.
About five kanji a day until day 28, each inside a word you can use. Day 29 has the longest passage so far. Day 30 has no new characters or patterns and ends on a passage twice as long as day 1’s, in all three sets.
A short explanation, then practice, always in the same order.
What flashcards are for, why the gaps between reviews matter, and how to read something you only half understand.
None of that is obvious the first time you learn a language, and the course is written for someone doing it for the first time.
You already read hiragana and katakana. Most of the first three weeks would be review. The placement test checks which words you already know, and Lingaku starts from there.
Keep a daily session, even a ten-minute one: clear the flashcards that are due and read one short thing. Read a lot, and read easy. Lingaku shows how much of each text you already know, so the easy ones are easy to find.
The Lingaku course picks up where this one stops: the same grammar points and words, more of both, and reading that gets longer as you go.
Day 1 has no new characters. It starts with how a Japanese sentence is put together.
