A 30-day Japanese reading plan

Read one chapter a day for four weeks, a whole series each week: two A1 series, then two A2 series, with every seventh day kept for rereading. On days 29 and 30, try a harder A2 story, then reread your very first chapter to see the change. It takes about 15 minutes a day, and a free-chapters version is below.

Length
30 days, about 15 minutes a day
Levels
A1 for two weeks, then A2
Series
Five, all in the Contos Japanese library (October 2026)
New chapters
26 in the full plan; 14 in the free version
Before day 1
Hiragana and katakana

What does the month look like?

Each week is one series of six chapters, read one chapter a day, plus a seventh day for rereading. The series are ordered so that one thing gets harder at a time: first more kanji, then longer chapters, then plain-form narration.

Chapter lengths and kanji shares measured on free chapters 1–2 of each series, Contos Japanese library, October 2026. Chapters 3–6 need Premium.
DaysLevelSeriesChaptersWhat's new this week
1–7A1Grandma's Secret Celebration1–6, then reread on day 7Polite -masu narration and lots of kana: about 16% kanji
8–14A1Letters Every Week1–6, then reread on day 14Shorter chapters with more kanji: about 24%
15–21A2The Midnight Editor at the Corner Bakery1–6, then reread on day 21Chapters nearly twice as long: 434–498 characters
22–28A2The Harbor Town Harmony1–6, then reread on day 28Narration switches to the plain past in chapter 2
29–30A2The Secret of Room Seven1–2The densest text of the month: about 35% kanji

Every chapter ends on a cliffhanger, which gives you a reason to come back the next day. Grandma's Secret Celebration, about a family secretly planning an 80th birthday party, closes its first chapter on a phone call from the community hall:

「ふみさんが 今、 ここに 来ましたよ。」

"Fumi-san ga ima, koko ni kimashita yo."

"Fumi has just come in here." The family thought the grandmother had gone shopping.

From Grandma's Secret Celebration, chapter 1 (A1)

What do you do on each day of the plan?

On reading days, follow the four blocks of our 15-minute reading routine: review yesterday's saved words, read the new chapter for the story, reread it slowly and save what stopped you, then reread yesterday's chapter.

Reread days are different. Read the whole week's series again in one go, without tapping wherever you can manage, and keep a tally of the words you still had to look up. That tally is your record for the month. If you can't finish all six chapters in 15 minutes, read the last three and keep the rest for the following Sunday.

Missed a day? Pick up the next chapter the day after. Don't read two to catch up; the plan works because the words come back daily, not because you finish on day 30.

Can you follow the plan on the free chapters?

Yes. Chapters 1–2 of every series are free, so the free version reads the first two chapters of seven series and puts rereading in the gaps. It has fewer new chapters, but every reread brings the same words back, which is how they stick.

Fourteen new chapters, all free, from seven series in the Contos Japanese library (October 2026).
DaysNew chaptersThe other days
1–7Grandma's Secret Celebration 1–2 (days 1–2); Letters Every Week 1–2 (days 4–5)Days 3 and 6: reread the two new chapters. Day 7: reread all four
8–14The Mystery Wallet 1–2 (days 8–9)Days 10–14: reread the six A1 chapters, two a day, tapping as little as you can
15–21The Midnight Editor at the Corner Bakery 1–2 (days 15–16); The Harbor Town Harmony 1–2 (days 18–19)Days 17 and 20: reread the new pair. Day 21: reread all four
22–28Tomorrow's Voice 1–2 (days 22–23)Days 24–28: reread the six A2 chapters, two a day
29–30The Secret of Room Seven 1–2Day 30: also reread Grandma's Secret Celebration chapter 1

The cliffhangers bite harder on the free plan, because chapter 3 is never next. Treat that as a reason to reread: each time through you catch more of what the story is hinting at.

Why these series, in this order?

We measured the free chapters of every A1 and A2 series in the library and picked series whose text reads cleanly, then ordered them by what a learner finds hard: the share of kanji, chapter length and the switch from polite to plain narration.

Free chapters 1–2, Contos Japanese library, October 2026. Characters count kana and kanji only. The last column is the share of words that are on our list of the first 100 Japanese words.

Two patterns guided the order. The two A2 series in weeks 3 and 4 use fewer kanji than some A1 series, so the step up to A2 is about longer chapters and more complex sentences, not a wall of new characters. And Room Seven, saved for the end, is the densest: more than a third of its characters are kanji, and its chapter 2 is told in the plain past, the way Japanese fiction is normally narrated. That makes it a fair test of the month.

Six or seven words in every ten in these chapters are on our list of the first 100 Japanese words, so learning that list before day 1 pays off from the first page.

How will you know the month worked?

Day 30 has a built-in test: reread chapter 1 of Grandma's Secret Celebration, the chapter you started with, and compare. Look for three changes:

A level change isn't the goal of the month: Contos moves you to A2 at 500 known words, whenever you reach them. The goal is the habit. The vocabulary researcher Paul Nation suggests that learners below the 2,000-word level read about a graded reader a week, and a series a week is that pace. A second month of the same rhythm, with new A2 series, is the right next step. Browse the A2 Japanese stories to choose them.

Start day 1: chapter 1 of Grandma's Secret Celebration, free, at A1.

Frequently asked questions

Do I need Premium for the 30-day plan?

Not for the free version. It uses chapters 1–2 of seven series, all free, with rereading days in between. The full version reads whole series, and chapters 3–6 of each need Premium.

What do I need to know before day 1?

Hiragana and katakana. Contos stories have no romaji or furigana, so you need to read both kana before you start. Kanji you can learn as you go, by tapping. The Japanese writing system guide explains how they fit together.

What if a week's series is too hard?

Stay on it, but read each chapter over two days instead of one, and push the plan back. If you lose the story completely, go back to the A1 weeks. Better a 40-day month than a skipped one.

Can I start the plan at A2?

Yes, if A1 chapters feel easy. Swap weeks 1 and 2 for two other A2 series from the A2 story hub, then carry on with week 3 as planned.

Why reread instead of reading something new?

Because a word you met once is easily lost. Rereading a chapter brings back its words while they are still fresh, and the second time you can attend to grammar. See rereading.
