Kanshudo Component Builder
Draw a component:
Type a component or its name:
Choose from a list:
Change component list
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.

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. 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.
Kanshudo Component Builder Drawing Help
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

Kanji components and radicals

Almost all kanji are actually composed of 'components' - elements which themselves have meanings, and often (but not always) are actually kanji in their own right.

Components vs radicals vs elements vs graphemes

In Kanshudo, we use the term 'component' to refer to any individual part of a kanji that is distinctly recognizable.
'Radical' is the standard term for only those 214 components which were historically used to index kanji in Japanese dictionaries. Each kanji has exactly one radical, but it might be composed of several other components in addition to the radical. Many components occur frequently in kanji, but are not classified as radicals. In Kanshudo, we make it very easy to see what components kanji are made up of, and also to search for other kanji that use those components.
You may also see the terms 'element' and 'grapheme'. Both are usually used in the same sense we use 'component'. Element is a fairly common direct alternative term. Grapheme is used more in the typographical world - for example, it is the standard term used when discussing Unicode (the text standard for the internet) character composition.

Components example

Let's take an example: the common kanji (green).
You can see that it is composed of three elements, 糸, 彐 and 水:
  • 糸 (thread) is a common component, and also a radical
  • 水 (water) is also a very common component, and a radical
  • 彐 is also common; originally it descended from 彑, a radical meaning 'pig's snout'. However, it appears in this form more frequently. So, given its resemblance to katakana ヨ (yo), in mnemonics we refer to it as 'yo', in the sense of give a yell or shout.
However, the right side of the kanji, 录, is actually another kanji in its own right, which appears in several other kanji as a component. So, in mnemonics, we use that composite kanji, so we can very easily find other kanji which use the same component (such as 録), just by doing a component search for 录. This component doesn't have a common meaning, so in Kanshudo we assign it a meaning based on its own components that makes it easy to remember when it is used.

Learning the radicals and components

To learn the components specifically, start with the 50 most common components. You can also learn components by learning the kanji that contain them - take a lesson. For a complete reference guide to all components and radicals, see All components and radicals.

Searching for kanji by component

Kanshudo includes a fantastic tool for searching for kanji by component - the component builder. If you can identify any component (the radical or any other component) in a kanji visually, you can quickly find that kanji. If you know the English meaning of that component, you can just start typing it, and Kanshudo will highlight matching components for you to select - this is much quicker than searching for components by stroke order. Read our how to guide, or just try a search.
