By default the Component Builder shows the most common Joyo kanji components (ie, components which are themselves Joyo kanji, or which are used in at least 3 other Joyo kanji). Select an alternative set of components below.



For details of all components and their English names, see the Component collections.

To find any kanji, first try to identify the components it is made up of. Once you have identified any component, search for it in any of three ways:
  1. Draw it in the drawing area
  2. Type the name in the text area
  3. Look for it in the list
Example: look up 漢
  • Notice that 漢 is made of several components: 氵 艹 口 夫
  • Draw any of these components (one at a time) in the drawing area, and select it when you see it
  • Alternatively, look for a component in the list. 氵 艹 口 each have three strokes; 夫 has four strokes
  • If you know the meanings of the components, type any of them in the text area: water (氵), grass (艹), mouth (口) or husband (夫)
  • Keep adding components until you can see your kanji in the list of matches that appears near the top.

The Kanshudo Component Builder can recognize any of the 416 components listed in the chart below the drawing area. Tips:
  • Draw a component in the center of the area, as large as you can
  • Try to draw the component as it appears in the kanji you're looking up
  • Don't worry about stroke order or number of strokes
  • Don't draw more than one component at a time

Kanshudo Kanji Builder

How to use Kanji Builder to build your kanji knowledge

Kanshudo Kanji Builder is a fun and challenging way to cement your knowledge of kanji! Read this guide to find out more.
1. The object of the game
The object of the game is to build a kanji from its components. It is actually surprisingly difficult to remember which components make up a kanji, and where they go. Kanji Builder forces you to recall the components and how they fit together. If you can remember the kanji's Kanshudo 'mnemonic', the short phrase that links the kanji's meaning with the meanings of its components, you will find it much easier. For more on mnemonics and how they help you learn kanji, read our guide, How to master the kanji.
Practicing building kanji will help them to stick in your mind. It's hard, but it's an effective way to learn, and it can be very addictive!
2. Setting your preferences
Click here to set your preferences.
You can play Kanji Builder with random kanji at any level, or with a subset based on kanji ring.
You can play in two different modes: study mode, and high score mode. In study mode, after you build a kanji, you can practice drawing it, and you'll also see links to study the components you were shown to choose from. (Learning the components and their names is an important shortcut to learning kanji faster.) In high score mode, you have five lives, and your goal is to build as many kanji as you can. You lose lives by guessing incorrectly or by using help. It's very challenging!
3. How to play
To play, just drag a component from the supplied list to the part of the grid you think it belong in, then let it drop. If you are correct, it will 'stick'. If you are wrong, it will float back to the component list.
Once you have correctly dragged all the components to the grid, the display will change to show you the normal handwritten version of the kanji, as well as the 'cascading kanji' view showing you the readings and meanings of the kanji and all its components in one place.
The grid shows you roughly where the components should be placed in relation to each other. In general, just drag components to the right squares - most kanji are formed of simple combinations of two or three elements next to or above each other.
For example, the very common kanji 見 (to see) is composed of two simpler components, 目 (eye), and 儿 (legs). This gives rise to Kanshudo's mnemonic - 'an eye on legs can see'.
To build 見, you would see a grid like this, with two boxes. You would need to identify the right two components (目 and 儿) in the supplied list. Then drag 'eye' to the top rectangle, and legs to the bottom. For practice, try to build 見 yourself now.
In some cases, components overlap. In these situations, when you drag a component over the grid, the box that needs multiple components will be shaded a darker color. For example, let's try 発 (emission). This is composed of three components, 癶 (hairy legs), 二 (two) and 儿 (legs). However, 二 and 儿 need to be placed on top of each other. So in this case, when you drag a component over the lower box, it will be shaded a darker color. Try to build 発 yourself now.
Some kanji use elements that surround other elements. In these kanji, the square which contains the surrounding element will light up when you drag a component over it, but you can only drop the kanji on the actual surrounding element.
For example, consider 道 (road), which is composed of ⻌ (move) and 首 (neck). When you drag a component over the L shaped box, the whole grid lights up. However, you can only drop ⻌ on the actual L shaped part, not the smaller box. Try to build 道 yourself now.
Since most kanji components are themselves kanji that can be broken down further, it would theoretically be possible to describe a complex kanji as a collection of many components. However, we don't think this is helpful. When deciding which components to highlight, we use the largest components that themselves have a meaning. As an example, consider 途 (another kanji meaning road). The top right element 余 could be described as a combination of 𠆢 (man), 于 (from), and ハ (eight). However, since it is a kanji in its own right, meaning 'surplus', we present 途 as the combination of just 余 and ⻌. Try to build 途 yourself now.
Some kanji are composed of a lot of elements! It can be very satisfying building these kanji out of their complex sets of components. For example, try building , , , , , (watch for the overlapping component!), or our favorite Jōyō kanji (another tricky one!), or even our favorite kanji !
4. Impact on your kanji mastery score
When you correctly build a kanji in Kanji Builder, it will affect your kanji mastery score for that kanji. If you correctly build the kanji with no mistakes, your mastery score will be increased to 3 (if it's already higher than 3, it won't change). If you do make one or more mistakes, your score will be increased to 2.
