されたほうがよろしいのではないでしょうか。

Change component list

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.

Components used commonly in the joyo kanji
Standard radicals (and their variants) only
All components and radicals

Full details of all components and their English names can be found here.

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.

Example

To find the kanji 漢:

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.
