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

One of the questions that comes up frequently as you study Japanese is: how many kanji are actually used in a given piece of Japanese?
To try to answer this, we analyzed the Wikipedia and Tatoeba corpora, both of which are freely available for download. We ran the entire text content through our parser to first identify separate sentences, and then identify kanji and other characters within each sentence.
We found that on average, sentences are 18 Japanese characters long, and of those 18 characters, 5 characters are kanji (the rest are kana or punctuation).
In practice, other types of reading material will have different averages. For example, analysis of a handful of articles in the Nikkei suggests somewhat longer sentences and much higher kanji counts. Analysis of a few sentences in a contemporary novel suggests much longer sentences, but a similar ratio of kanji to other characters. Since a typical page in a Japanese paperback has space for 5-600 characters, this implies you would encounter over 100 kanji per page on average.
We'll update this article as we gather more data on this topic.
