How do I go about learning kanji?
Perhaps the most common question we get is how to get started learning kanji, and next most common is how to persevere once you've started!
We have put together a comprehensive introduction to both topics, in an article which will take you step-by-step from absolute beginner to kanji expert. Read How to master the kanji and put your studies on a foundation for success!
If you are just getting started with Japanese, we have a guide and a series of lessons designed especially for you. Start with Getting started learning Japanese, and then try a Beginner Lesson.
How many kanji are in Kanshudo?
Currently there are 13,615 kanji in the Kanshudo system. This includes:
  • All 2136 Jōyō kanji ('regular use' kanji), the official Japanese government list of kanji used in government documents, 1006 of which are taught in primary school (the Kyōiku Kanji), and the remaining 1130 of which are taught in secondary school (the Secondary School Kanji). (The 2136 includes the 196 characters that were added in 2010.)
  • The 862 Jinmeiyō kanji (kanji officially allowed for personal names).
  • Many Hyōgaiji ('outside the chart' kanji), i.e. kanji not in either set, but that are in use, for example in novels or on the web.
Additionally, many of the kanji in the system have variants, either still in use or occurring in older texts, and the variants are linked to/from the modern accepted form. Finally, Kanshudo includes many characters that occur as common components of other kanji.
How many kanji have mnemonics in Kanshudo?
Currently Kanshudo contains 3575 distinct mnemonics.
How about vocab and example sentences?
Currently Kanshudo contains 255,894 individual dictionary entries, and 151,330 Japanese/English example sentences.
Why do some kanji not have mnemonics?
Some of the simpler kanji do not have mnemonics, because they are the basic elements we refer to as 'components' that make up other kanji. Our goal is to present each kanji with a mnemonic that includes the simplest possible component parts of that kanji. However, at a certain point the kanji can't be broken down any further, and you just have to memorize the meaning of the components, in the same way you have to memorize hiragana and katakana. This includes some of the more common kanji (think of 一 or 人), and many of the 'radicals' (the traditional means of organizing lists of kanji - a subset of all kanji 'components').
Your first step in learning the kanji should be to learn these components in parallel with learning the most frequent kanji. Don't worry! This is easier than it sounds, because the components are used to make up all other kanji - so every time you look at a more complex kanji, you are also refreshing your memory of its components. The Kanshudo cascading kanji™ system of presenting each kanji followed by its components, and their components, and so on, makes this especially easy.
What does a frequency of 100 mean?
A frequency of 100 means the kanji is the 100th most commonly used kanji according to the Japanese government. 1 = most common; 3500 = least common of the kanji with frequency data. (Even less common kanji have no frequency entry.) For details on the frequency data used in Kanshudo, see the Introduction to the kanji.
What's the difference between radicals and components?
Both radicals and components are 'elements' from which more complex kanji are made up. The 'radicals' are a standardized list of 214 kanji elements (plus their variants) which were historically used by dictionaries to index the kanji. Before computers, kanji were typically only indexed by one element, so one element was chosen (sometimes arbitrarily) as the primary classifier. Today, however, we can find a kanji by looking for several elements at once, including elements that are not considered 'radicals' but are nevertheless in common use. We call these components.
For more information on components and radicals, see here.
For a full list of all components and radicals, see here.
For more information on the standard list of Japanese radicals, see this Wikipedia article (⇗)
Do you use English or American spelling in the readings / mnemonics?
Great question ... you may be asking this because you have noticed an inconsistency. That's very possible, and if so it's our creator's fault - he is English, but has lived in the US for over fifteen years! In general Kanshudo is standardizing on American spelling, so if you see any errors, please let us know. Thanks!
Where does the name Kanshudo come from?
It is a pseudo-Japanese word built from the characters 漢習道, which means 'the way to kanji mastery'. For more information, see About Kanshudo. To learn about the kanji, look up Kanshudo in quick search.
Where can I read more about Kanshudo online?
You can read some user comments in our Testimonials page. Check out our Facebook page ⇗ - we post updates on new features and articles of general interest to Japanese learners regularly. We are also on Twitter ⇗. You can also read some discussion about us on Reddit ⇗. Kanshudo has also been reviewed by JapanTree ⇗.
Can you recommend a good Japanese textbook?
Yes! We can actually recommend several. Our Textbook Companion supports Adventures in Japanese, Genki, Minna no nihongo, and Japanese for Busy People. Each has different strengths and is suitable for a somewhat different audience.
  • Adventures in Japanese is the standard high school text in the US.
  • The Japanese for Busy People series is perhaps most popular amongst expat business people studying Japanese, as it takes a more conversational approach, and introduces kanji more slowly.
  • Genki is a very popular series, created by the publishers of the Japan Times, and provides a balanced mix of kanji and vocabulary.
  • Minna no Nihongo is a series that has stood the test of time, and the materials are available in several languages for students whose native language is not English.
Whichever textbook series you choose, the Textbook Companion enables you to benefit from all the power of Kanshudo while working through your textbook.
Why do I see squares in place of Japanese characters?
It's possible your device does not have the full range of Unicode characters that are needed to display some of the rarer characters. It's also possible your specific setup has an encoding problem which is just corrupting the display. The following simple test should diagnose the problem:
Your system Should be Notes
𤰔 Ch onereason 277ade8be1b562d2b0547b74140b5fec307689a79304e1725201d2dd304b52df This character is not included in the character set on various mobile devices, including iOS 1 through 9. If you are on a mobile device, and you can see the other characters in this list, there are only a handful of characters in the Kanshudo system that you will not be able to see.
Ch kan b9a15beef656627bad54fecc724f6f1cc49dda9f00dcc8522266138ff89bb86a This character is a common Jōyō kanji, and should be visible automatically on all modern computers, tablets and smartphones. If you do not see this character, you may be using an older system, or you may just have an encoding problem. In the View menu of your browser, look for an item called Encoding or Text Encoding and check it is set to UTF-8.
𠂉 Ch man 8a2c514fdde5f7fda86f79dbe0db8ede1668f6e6b8e79820212c507e60f077a9 This character is a commonly-used component in kanji (for example, it appears at the top of 年). However, it is not visible in some versions of the Chrome browser or the Android operating system.
What is Kanji Mastery and the Kanji Mastery Score?
Once you have registered with Kanshudo, the system monitors your interactions with various kanji - for example, every time you guess correctly or incorrectly in the quiz or a game, every time you study a flashcard, every time you tag a favorite. From these interactions, we infer your knowledge of that kanji and other similar kanji. Based on these inferences, we assign a mastery score from 0-4 for you personally to every kanji.
These mastery scores are visible to you from the kanji details page of any kanji, and aggregated into the Kanji Wheel (see the next question).
What is the Kanji Wheel?
The Kanji Wheel is a visual representation of your entire knowledge of Japanese kanji. It is a simple and fun way to monitor your progress, and help you focus your studies.
The wheel is a set of 7 concentric rings, representing Japanese characters of different difficulty levels. The inner ring (1) represents hiragana and katakana, ring 2 represents the most common basic kanji, through to ring 7 which represents all non-Joyo kanji. Each ring is colored according to your knowledge of the kanji in that ring. You can click on different sections to instantly identify kanji you know well (or badly), and then automatically generate flashcards etc to guide your studies.
Visit your personalized Kanji Wheel now. For a more detailed overview of the Kanji Wheel, see our how-to guide, Your Kanji Mastery Score and Personalized Kanji Wheel.
I just took the Quiz - why isn't my Kanji Mastery Score higher?
The Kanshudo system infers your knowledge of kanji based on your interactions with it, and we try not to go too far just based on the Quiz alone, which is only one data point. So for example, we don't automatically flag you as mastering all kanji in level 1, just because you got a quiz score that indicates you know kanji in level 5. For many reasons, you may have learned kanji at higher levels sooner than some kanji at lower levels, and we don't want to flag kanji you don't know as mastered.
What we do is give you the option to specify your mastery level of a ring yourself if it seems likely to us that you have mastered it. So, for example, if you get a quiz score higher than 750 (which corresponds to knowledge of about 750 kanji), it's highly likely that you have mastered kanji in rings 1-3 (hiragana+katakana, plus the most common 250 kanji). So, in your intelligent study recommendations list (the list that appears below your personalized Kanji Wheel), you will see an option to flag rings 1-3 as mastered.
If you yourself are not sure whether you've mastered kanji in lower rings, we offer another option - eg in this case, to flag ring 3 as partially mastered, and rings 1-2 as mastered.
If you are not sure, don't click on either of these options! As you keep using the system, your score will gradually improve automatically as we gather more data. You can also edit your mastery score for any individual kanji directly from the kanji details page.
I've already mastered hiragana/katakana - how do I reflect that in my Kanji Mastery Score?
Congratulations! You have already taken a key first step, and Kanshudo can reflect that in your score. There are actually several ways to do this:
  1. The first thing to do is to take the Quiz. Your score will help to set a number of different variables in Kanshudo, which will 'infer' how well you know kanji below the level you get to, including hiragana and katakana.
  2. Depending on your Kanji Mastery Score, at a certain point you will be given some new options in the study recommendations which appear below your personalized kanji wheel. These options will let you set ring 1 (the hiragana/katakana ring) as partially mastered or mastered. See also I just took the Quiz - why isn't my Kanji Mastery Score higher? for more information.
  3. You could create and study flashcards for the hiragana and katakana You can create them by clicking on ring 1 of your Kanji Wheel, or directly from the hiragana / katakana introduction pages). That will directly set the mastery score for each card as you study it. If you need a bit of revision, this might be worthwhile.
  4. You can also directly edit the mastery scores of individual kanji on the details page. Of course, this would take a long time, so we don't recommend this over the options above. For example, here's the page for hiragana あ - scroll down to the section labeled My Kanji mastery to see your current level.
How does the Quiz help me understand my kanji level?
As with English vocabulary, kanji knowledge tends to operate in 'bands' based on frequency, i.e. how often you encounter each kanji. In other words, if you know some kanji in band 1-100 (where 1 = the kanji you encounter most frequently of all), you will probably know most of them. If you don't know one kanji in band 500-600, it's quite likely you won't know others. The Quiz helps you identify what frequency band you have reached, which enables you to focus your learning where it will be most effective.
Of course, recognizing kanji when you are shown their readings is a lot easier than coming up with the meanings without being shown anything, or (hardest of all) writing the kanji when being told a reading. But recognizing the kanji with some context is a great place to start, and the Quiz helps you understand your current level.
The Quiz is most useful if you are an intermediate or advanced kanji learner, because it will help you make your studies more efficient. But the Quiz can be fun to take for any level of student, and testing yourself is a form of studying, so go ahead even if you are a beginner!
Note: you can practice the Quiz here, or take the full Quiz here when you are ready. You can take the Quiz as many times as you like.
How does the scoring work in the Quiz?
The Quiz scores your kanji ability as follows:
  • You will be given a series of questions, each of which resembles the Kanji Match game - you drag a kanji on the left over to its correct readings on the right.
  • The questions are drawn randomly from kanji within a frequency band, starting with the most common 100 and gradually working up. Before leaving each band, you are also randomly shown kanji in the full frequency range up to your current band.
  • In each band, you get points for questions you get right. When you get a certain number right, you move to the next frequency band up.
  • However, if you get a question wrong, the number of questions you need to get right to move to the next frequency band goes up! In other words, as you make mistakes, it gets harder to progress to the next level.
  • The Quiz ends when you make three mistakes in the frequency band you are on, or a total of seven mistakes across all frequency bands you've attempted.
Note: you can practice the Quiz here, or take the full Quiz here when you are ready. You can take the Quiz as many times as you like.
What are Study Points and how do I earn them?
Study Points are 'rewards points'. Every time you interact with Kanshudo, to study a lesson, learn a flashcard, play a game, tag a kanji as a favorite etc, we reward you with study points. As you accumulate study points, you are automatically awarded coupons for free use of the system. The first coupon, WHITE, requires only 250 study points, which you can earn very quickly. The WHITE coupon gives you two free months (or more with a Pro subscription) of completely free access to Kanshudo - during which you can earn more coupons.
If you study on Kanshudo consistently, you will earn study coupons regularly. Our heaviest users actually earn completely free use of the system.
Why do I need to register for Kanshudo?
Kanshudo helps you master the kanji, by helping you study the kanji you don't know in a structured way.

By default the component builder shows the most common components (themselves joyo kanji, or used in at least 3 other joyo kanji). Select an alternative set of components below.

Full details of all components and their English names can be found here.
Help with the component builder
For detailed instructions, see the Component builder how to guide.
To find any kanji, first try to identify the components it is made up of.
For any components you recognize, if you know the English meaning or name, start typing it in the text area. Full details of all components and their English names can be found here.
Alternatively, count the strokes of the component, and scan the list to find it visually.
To find the kanji :
  • Notice that it is made of several components: 氵 艹 口 夫.
  • 氵 艹 口 all have three strokes, so you could look in the list in the 3 stroke section. 夫 has four strokes.
  • Alternatively, you could start typing 'water' (氵), 'grass' (艹), 'mouth' (口) or 'husband' (夫) in the search area, and the components will be highlighted in yellow.
  • Keep adding components until you can see your kanji in the list of matches that appears near the top.
