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.

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

ことはない
means
there is no need to ~, ~ never happens
じぶん
自分
める
ことない
You don't have to kick yourself.
てしまった
からといって
わる
おも
ことない
There's no need to feel bad just because you fell asleep.
This construction is similar to ことがない, and in many cases they are interchangeable. ことがない is often used with a past form verb (to mean 'has not happened'), and it is less common to use は in this way.
If the clause containing こと~ない is itself the subject of a larger sentence, it would be preferable to use は:
きょうと
京都
った
ことはない
なら
奈良
なんど
何度
った

I've never been to Kyoto, but I've been to Nara several times.
