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

Grammar detail: かどうか

かどうか - whether or not

Grammar games:
plain form clause A
clause B
(clause B) whether or not (clause A)
かどうか functions in a very similar way to the English phrase 'whether or not', with the key difference that in English, clause A / B would be reversed.
I do not know if it will rain tomorrow.

Can you tell if it will rain tomorrow?
Clause A is usually a description of a situation - 'rain tomorrow', or 'the bathroom is in use'. Clause B can be a statement of knowledge or intent ('I don't know' or 'I would like') etc.

Please tell me whether it is new.
I don't know whether or not I want to read it.
A simple way to construct sentences using かどうか is to start with a question (converting the final verb into the plain form if there is one and it's in the polite form), add どうか after the question marker か, and then add clause B. For example, let's start with the following simple question:
Can Lucy speak Japanese?
This sentence uses the polite form, so first we turn the polite form verb ことができます into the plain form, ことができる. Then we add どうか to the question marker か so that we have our key phrase かどうか, and the meaning '... whether or not Lucy can speak Japanese'. Now we can add 'clause B', which can be anything we wish to convey - in this case
っていますか ('do you know ~'):

Do you know whether or not Lucy can speak Japanese?
