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

The idea of 'must do' (or must not do) can be expressed in Japanese in various ways.
Two of the most common are:
verb なくて form + はいけません
 
have to do
verb なくて form + はなりません
 
have to do
Both forms are roughly equivalent. A slight nuance is that the first form implies you think there is no other choice, whereas the second form implies that you have been told to do something, or it is otherwise a burden to you. In both of these cases, the initial form, なくては (the negative te form, which can be translated roughly as 'not doing'), can be strengthened to なければ (which means 'if I don't do').
Other ways to express obligation include:
ねばならない
 
have to do, feel obliged to do
To express a negative obligation (must not do), use the て form instead of the なくて form, for example:
verb て form + はいけません
 
must not do
