Various practice drills for all Jōyō kanji (2141 kanji, 2010 official list) and the 5 levels of the Japanese Language Proficiency Test (N5 to N1). Choice of the JLPT or Jōyō Kanji order.

  • Ten multiple choice drills on meanings, On-yomi (Chinese readings) and Kun-yomi (Japanese readings), radicals and elements.
  • Two puzzle practice drills including stroke order animation.
  • Two writing practice drills with stroke order animation.
  • Stroke order independent Handwriting Recognition (single kanji)
  • Optical Character Recognition (OCR) (single kanji)

    Reading actual texts is by far the best way to learn the written language, but flashcard programs have always been useful tools.
This Android app will help you get a sense of how much you already know, brush up on your Japanese, and prepare for a test.
We also believe that a certain amount of rote learning is a necessity when it comes to studying the kanji.

This app was thus conceived as a reviewing tool or a drill tool.
It is designed for students who have already started to learn Japanese. It is therefore assumed that you can read katakana and hiragana signs.
This application is the Android version (with added functions) of the Java applet "Drill the kanji" that has been freely available since 2001 at http://www.asahi-net.or.jp/~ik2r-myr/kanji/kanji1a.htm

   Radicals (bushu) and elements

A list of 259 radicals and elements, a flashcards stack and four multiple choice drills. For more details, please read the specific presentation page:

   The Flashcards / Review mode

Suggestion on how to use the flashcards:
1) In the Drill range selection panel select the range of kanji you want to concentrate on.

2) In the Flashcards panel hide the meanings and examples and flip through the cards.
If you think you know the displayed kanji, mark it as "known" with a touch on the +/- icon (toggle).
Kanji marked as "known" will be excluded from the On, Kun and Meanings drills, until you reset them to the "unknown" state, either individually or in a batch in the Settings panel.

Your choices will be saved in the database and you can safely turn off your device.

Depending on your choice in the panel "Drill range selection", these flashcards will follow the Jōyō Kanji order or the order of the five levels of the Japanese Language Proficiency Test
There are 2141 cards in the database.

Each card displays a kanji, its meaning(s), its common On and Kun readings and up to three compound examples.

You can toggle the visibility of items on the cards with a touch on the various panels.

   The drills or practice tests

The application offers four types of multiple choice questions or tests (MCQ).
1) The Meanings 1 MQC displays 4 kanji.
2) The Meanings 2 MQC displays 1 kanji and 4 sets of meanings from which to choose from.
3) The Kun-yomi and On-yomi MQC display 1 kanji and ask you to choose the correct reading(s).

Whenever you make a mistake, you can have a look at the corresponding card with a touch on the eye icon  
You can do the same with the correct answer and display the corresponding card.

You will be able to resume any interrupted exercise where you left it, even if it is killed by the system when it needs more memory.


In the "Encore!" stack, you will find kanji you should concentrate on.

As you go through the drills, the program memorizes the wrong choices you made, together with the kanji you should have chosen.

The behavior of the cards is the same as in the Flashcards / Review stack : you will be able to hide or display the meanings and examples with a touch on the panels (toggle).

You can also mark kanji as "known" in order to exclude them from future drills, until you reset them to the "unknown" state.

The cards in the Encore stack are displayed in an endless loop, whether you use the Next or Previous buttons. Their order is randomized each time you open this activity.
The Reset button enables you to empty the Encore! stack of cards.


The Report panel displays the results of completed drills only.

In this version your scores are not saved automatically. If the application is killed by the system when it needs more memory for another task, the displayed data will be erased. Therefore, if you wish to keep track of your progress, you must save your scores as an email message. Asahi Kanji will launch your default mail program and populate a message with your results. You can save this message as a draft on your device or send it to yourself.

This application has no access to your address book and you will have to fill in the mailing address yourself.

When your default mail program is launched Asahi Kanji is sent to the background (it disappears).
After saving your scores use your device Back button to return to Asahi Kanji.

You will be able to resume any interrupted drill.


Font size

Android devices screens come in all sizes, densities and proportions and changing font sizes is best done by the system itself.
You can increase the font size in Settings / Accessibility / check "Large Text".


In the Flashcard and Encore! drills you can mark or unmark the radicals cards as "known" with a tap on the +/- icon.

Radicals marked as known are then excluded from the drills.

After you reset the whole stack of cards to the "unknown" state, all radicals will again be included in the drills.

    Memory management

Mobile phones are not computers and the telephony function has a priority over this application.
This application can be killed by the system in case of low memory in order to let you receive and give phone calls, play a video, etc.
In that case, it will save its state and when you restart it, you should be able to resume any drills where you have left them.


As is customary, the On readings (the Chinese readings or on-yomi) are given in katakana and the Kun readings (the Japanese readings or kun-yomi) in hiragana. If a kanji is a verb stem, the inflectional endings (usually written in hiragana after the kanji) are shown in parenthesis. A kanji may have many meanings or interpretations. Due to lack of space, only the most common meanings are shown. One to three examples are given for each kanji. These examples can be either common compounds or common expressions. We limited ourselves to frequent compounds or uses of the kanji, which explains the blanks.
