10 questions a round. About 3 minutes.
For parents
Answer the kanji in the sentence that appears on the blackboard. Pick from the choices below, then tap “Enter”. That’s all.
The kanji you find hard show up more often. Get several right in a row and you win a picture.
A drill for the kanji taught in Japanese elementary school. A round is 10 questions and takes about 3 minutes. It covers 662 characters and 3,347 questions for school years 1–4, asking both the reading and the character itself.

A short phrase appears, and one of the kanji in it is yours to answer.
Kanji you have not learned yet come with small furigana above them, so you do not need to read the whole phrase.
Either way, just pick from the ten choices shown below. Tapped the wrong one? “Clear” takes it back.
Sometimes a whole compound word such as 日本 is asked at once. Then two boxes appear — pick both characters, then tap “Enter”.
When you get it right on the first try, the mark depends on how fast you were.
The bar at the top of the blackboard shows how fast you are going. A wrong answer never gets an ✕ — if no mark appears, just think again.
Every 5 correct answers in a row, you win one picture. Your pictures go into the Collection — 58 in all.
Once you have a picture, it stays yours forever. A “?” is one you have not won yet — you never know which is coming until you get it.
The app remembers the kanji you got wrong, or have not seen for a while, and puts them first next time.
On the “Problems” screen you can choose which kanji to practise, year by year. One square is one reading — the same character with a different reading is its own square.
Miss the same question twice and the app shows you the answer, then brings it back three questions later — so you never end up stuck.
A missed kanji stays on the list until you get it right — it does not disappear the next day. “Try again now” on the Home screen drills just those.
How many you answered, how fast you were, and how many you got right — every day is recorded. A perfect day earns a 💮.
Play every day and your “day streak” keeps growing. The kanji you are weakest at are listed as chips, too.
You can ask only readings, only characters, or mix the two. You can also change how many questions come in a round, and turn sound and vibration on or off.
You can turn on “See answer” too. But looking is recorded as a wrong answer, and that question will come back to you later.

The unit of learning is one character paired with one reading. 右 read “migi” and 右 read “yuu” are counted separately, each with its own record. Characters answered wrongly, or not seen for a while, are asked first.
The range is chosen by school year (year 1 by default). Each square is one reading, shaded by how weak it is. Eight sort orders are available — curriculum order, reading, last answered, accuracy and so on — plus an index that jumps by first kana.
Years 1–4 are included: 662 characters and 3,347 questions. Years 5 and 6 can be added by dropping in another data file.
Reading mode shows the character and asks for its reading; writing mode shows the reading and asks for the character. The default mixes them at random, one per question; either can be fixed in the settings.
Answers are picked from ten choices. The choices are built on the server; in writing mode they include characters of the same year with the same reading, so guessing does not get you far — and no handwriting input is needed.
Within the sentence, characters already mastered are shown as kanji and the rest carry furigana. Characters from earlier school years are shown as kanji too (this can be changed). Compounds such as 日本 are asked whole once the other character is known.
Miss the same question twice and the app shows the answer, then brings that question back three questions later, so a child is not left stuck.
A missed character stays until it is answered correctly — it is not discarded the next day. “Try again now” on the Home screen drills only what is unresolved.
“See answer” is recorded as a wrong answer the moment it is used. Looking is not a bad thing — it is simply recorded, and the question comes back later. A wrong answer never shows an “✕”; the signal is the absence of a mark, plus sound and vibration.
Each day’s answer count, average time and accuracy are kept, and a 30-day chart shows the days kept up. The 24 weakest characters are listed as chips, each with its reading.
Red and green are not used as a pair. Colour vision differs from person to person, so the scale is shades of a single colour.
Everything a child is meant to learn from — the sentence on the blackboard, the kanji grid, the answer choices — is set in a textbook-style typeface (Klee One). The rest of the interface uses a rounded gothic face.
A rounded face softens every stroke end, so the stops, hooks and sweeps that define correct kanji shapes disappear. Fine for reading, but not a model to learn from — hence the switch for the characters being studied.
No name, no password — open it and start. Without signing in, the record is tied to the browser session.
As a guest, the record is lost if the browser’s data (cookies) is cleared. Sign in with Google to keep it. Everything played as a guest carries over to the account, and can be continued on another device.
Note that a guest record is not merged into an account that already has one (there is no right answer to which numbers to keep). One account is one child — for siblings, sign in with separate accounts.
The app itself is available in Japanese and English (the JA / EN switch in its header).
Every 5 correct answers in a row wins one hand-drawn picture — 58 in all. Once won, a picture never goes away. (The original faded them out over time; that was dropped — there is no reason to take away what a child has collected.)
The marks work the same way. Speed only counts on a first-try answer — a correct answer after a miss gets a different-coloured circle, however fast.
