Give it 15 minutes a day: two minutes reviewing yesterday's saved words, five reading one short graded chapter for the story, five rereading it slowly and saving what blocked you, and three rereading yesterday's chapter. A free A1 chapter in the Contos Japanese library averages about 29 short sentences, which fits that window.

What does the 15-minute routine look like?
Four short blocks, in the same order every day. The order matters more than the exact minutes: old words first, while you are fresh, then the new chapter, then a quick look back.
| Minutes | What you do | Why |
|---|---|---|
| 0–2 | Review the flashcards you saved yesterday | A word met once fades fast unless it comes round again |
| 2–7 | Read today's chapter straight through, for the story only | You learn more from text you understand than from text you decode |
| 7–12 | Read it again slowly; tap only the words that stop the meaning, and save them | On the second pass you have the time to notice particles and verb endings |
| 12–15 | Reread yesterday's chapter, saying one paragraph aloud | A second reading is faster, and saying the kana aloud checks you can decode them |
The first block rests on a warning from the vocabulary researcher Paul Nation: what you learn about a word from one reading is "very fragile", and it is lost if you don't meet the word again soon. Two minutes of review plus a reread of yesterday's chapter gives every new word two more meetings within a day. Spaced repetition and rereading explain why both help.
How much Japanese fits into 15 minutes?
One chapter, at the right level. We measured the free chapters 1–2 of every series in the Contos Japanese library (October 2026): the sentences get longer as the levels rise, and the chapters hold more of them.
| Level | Sentences in a free chapter (average) | Characters per sentence (average) | What gets harder |
|---|---|---|---|
| A1 | 29 | 10 | Mostly short, polite present-tense sentences |
| A2 | 36 | 12 | Plain forms in the narration; clauses before nouns |
| B1 | 35 | 15 | Plain past narration; joined sentences |
| B2 | 41 | 16 | Longer chapters and chains of verbs |
At A1 a typical sentence is about ten characters long, so both passes fit easily. By B2 there are more sentences and each is longer, so one chapter can fill the reading blocks on its own. If it no longer fits, read the new chapter once on the first day and again on the second, instead of trying to do both passes at once.
What should you do when a chapter is too hard?
Some days the chapter wins. Watch for these signs on the first read, and pick the matching fix:
- You lose the plot by the second paragraph. Drop down a level for a week, or reread an easier chapter you already know.
- You can follow it, but you stop on almost every kanji. That is normal early on. Keep reading for the story; save only the words that come back.
- The kana themselves slow you down. Spend the 15 minutes reading one chapter aloud, slowly, with no taps. Fluent decoding comes first.
- One word blocks a whole sentence. Tap it. That is what the second pass is for.
Here is the kind of word worth tapping. In this line from an A2 hotel mystery, the plot depends on 予約 (reservation): without it, the next sentence, in which nobody ever checks in, makes no sense.
毎月 十五日、 七号室 が 予約 されます。Maitsuki jūgonichi, nanagōshitsu ga yoyaku saremasu.
How should the routine change through the week?
A series of six chapters lasts almost exactly a week at a chapter a day, which makes a simple rhythm:
- Monday to Saturday: one new chapter a day, using the four blocks.
- Sunday: no new chapter. Reread the week's chapters in order, without tapping where you can, and notice how much faster they go.
- Next Monday: start a new series, or the same story at the next level up if one exists.
Chapters 1–2 of every series are free, so a free week works too: two new chapters from each of two or three series, with rereads in between. Our 30-day Japanese reading plan lays out a month day by day, in both versions.
What else can you read for Japanese practice?
The routine works with any text at your level. Two free sources worth knowing:
- NHK's NEWS WEB EASY (やさしいことばニュース) carries news written in Japanese that is as easy as possible, for foreign residents of Japan and for children. It is a good next step once A2 stories feel comfortable.
- Tadoku graded readers (にほんごたどく) offers free Japanese graded readers from Level Start to Level 5, readable online or as PDFs, some with recorded narration and some with furigana.
Contos stories differ in three ways: each chapter is part of a series that ends on a cliffhanger, the text has spaces between words, and there is no furigana or romaji. Tap any word for its meaning. Mixing sources is fine; the habit matters more than the source. For why reading works at all, see learn Japanese by reading.
How do you know your reading practice is working?
- The first read gets you the story. Early on you need the second pass to know what happened. With daily reading, the first pass slowly becomes enough.
- Your taps per chapter fall. Reread a chapter from a month ago and count the words you still need to tap.
- Words start recognising themselves. The particles, then common verbs such as 言う and 見る, stop needing attention. Our list of the first 100 Japanese words shows which ones come round most.
- Your known-word count climbs. Contos moves you from A1 to A2 at 500 known words.

Is 15 minutes a day enough to learn Japanese?
It is enough to build a reading habit that lasts, and steady daily reading adds up. It isn't fast: the US Foreign Service Institute puts Japanese at 88 weeks of full-time training for professional speaking and listening. More time helps, but a routine you keep beats a long one you drop.
Should I read Japanese out loud?
For part of the time, yes. Saying a paragraph aloud shows whether you can turn kana into sound without hesitating. Keep most of your reading silent, though, because silent reading is faster. Our reading out loud page weighs it up.
What if I can't read kanji yet?
Start anyway, once you know hiragana and katakana. About a quarter of the characters in Contos A1 chapters are kanji; tap the words they belong to and the common ones soon become familiar. The Japanese writing system guide explains how the scripts fit together.
Is it better to read new chapters or reread old ones?
Both, every day. New chapters bring new words; rereading brings back yesterday's while they are still fragile. The routine gives about two thirds of the time to new text and the rest to review and rereading.
When is the best time of day to read?
Whenever you can do it every day. Tie it to something you already do, such as a commute or a morning coffee, so you don't have to remember it. See habit stacking. Consistency matters more than the hour.
