How to use the Kanji Wheel to guide your Japanese studies

The Kanshudo Kanji Wheel™ visually illustrates your entire knowledge of Japanese kanji, and provides you with intelligent study recommendations based on your progress. It is the most effective intelligent learning system available for visualizing your Japanese knowledge, and guiding your Japanese studies.
Visit your personalized wheel any time by clicking the symbol at the top right of any page.
1. The seven rings of the Kanji Wheel
The Kanji Wheel enables you to visualize your entire knowledge of the Japanese kanji in one place. The wheel consists of seven rings, each of which represents a different set of Japanese characters.
The center of the wheel, ring 1, represents the hiragana and katakana. Rings 2-6 correspond to the kanji required for JLPT levels N5 - N1 respectively. Ring 7, the outer ring, represents 'everything else'.
Ring Contents Characters
1 Hiragana + katakana 138
2 Basics: JLPT N5 80
3 Essentials: JLPT N4 170
4 Progress: JLPT N3 370
5 Intermediate: JLPT N2 380
6 Advanced: JLPT N1 1136
7 Expert: Beyond the Joyo 1726

2. Kanji mastery levels
Every time you interact with Kanshudo, Kanshudo assesses your knowledge of the kanji you encounter, and assigns a level from 0 (no knowledge at all) to 4 (complete mastery). Each ring in the Kanji Wheel shows you how many kanji are at each level. The levels are color-coded, so you can see at a glance how you are doing with a ring. Your goal is to reach level 4 mastery of all kanji in all rings!
Color coding
When a ring is not highlighted, the colors represent your mastery levels as follows:
 Level 0   1   2   3   Level 4

How Kanshudo sets your mastery level for a kanji
Kanshudo assigns levels automatically based on your interactions with the system. Levels can be affected by almost any interaction, including games, quizzes, favorites, lessons and flashcards. For example:
  • Matching a kanji correctly first time in the Quiz or Kanji Match will set your level to 2 if you have not encountered that kanji on Kanshudo before. However, if your level for that kanji is already higher than 2, it will not be affected.
  • Studying a flashcard will affect your level in various ways. If you study the card at least once, you'll get a level of 1. If you study it multiple times, you'll get 2. If you mark it as 'learned' (by clicking 'Only just' or 'Easy' when you study the card), that will set your level for that kanji to 3. To get a 4, you need to study and review the card enough times that your study interval* reaches 6 months or more. This is true mastery of a kanji!
  • When you complete a Quiz, Kanshudo will 'infer' a knowledge level for some kanji based on how far you got in the Quiz. The Quiz is based on kanji frequency, so a score of 1000 implies you have at least passing knowledge of most kanji with a frequency up to 1000. So even though you may only have answered 20-30 questions, Kanshudo will set mastery levels for other kanji with frequencies lower than your end point in the Quiz.

3. My kanji mastery score
Your Kanji Mastery Score™ is a number from 0-100 which consolidates all your individual kanji levels. Each ring, each level within that ring, and each kanji within that level, contributes to the total. As you study, your Kanji Mastery Score will rise steadily. You can directly visualize your progress along the road to Kanji Mastery!
Level 4 mastery of all kanji in all rings will give you a kanji mastery score of 100. Each ring contributes to your mastery score as follows:
Ring Max points
1 10
2 20
3 20
4 15
5 15
6 15
7 5

4. Intelligent study recommendations
Based on your personalized Kanji Wheel, Kanshudo makes intelligent study recommendations as you progress. Check your wheel often to see your progress and guide your Japanese studies!
5. View and study kanji directly from the Kanji Wheel
One of the most useful features of the Kanji Wheel is that you can immediately see which kanji are at which level. When you click on any sector or ring, the study panel to the right of the wheel displays a color-coded summary of the kanji in that sector, or every sector in a ring. Next to each sector summary you will see two links, VIEW and STUDY.
Clicking VIEW will take you to a search view showing you all kanji in that sector. From there, you could Favorite any kanji to study it.
Clicking STUDY enables you to instantly create Flashcards for the kanji at that level in that ring.

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.

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.
