By default the Component Builder shows the most common Joyo kanji components (ie, components which are themselves Joyo kanji, or which are used in at least 3 other Joyo kanji). Select an alternative set of components below.

For details of all components and their English names, see the Component collections.
Kanshudo Component Builder Help
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: Japanese verbs and verb conjugation

Japanese verbs and verb conjugation

Japanese verb conjugation is actually quite straightforward compared to some languages. There are only a small number of irregular verbs, relatively few conjugations, no cases (to indicate who is speaking, gender, singular/plural etc), and regular verbs follow fairly simple rules.
Verbs are classified into two main groups, and a verb's group determines how it is conjugated. The names of the groups actually tell you how to conjugate the verb - it's a lot simpler than it sounds! The two groups are:
  • 'Ichidan' (in Japanese
    , literally 'one level verbs'). 'Ichidan' verbs are also often known as 'る' form verbs, and sometimes as 'Group 2' verbs.
  • 'Godan' (
    , 'five level verbs'). 'Godan' verbs are often known as 'う' form verbs, and sometimes as 'Group 1' verbs.
We recommend you use the terms
- they are more descriptive, and they're the terms Japanese people use.

Ichidan 一段 (いちだん) 'る' form verbs

Ichidan verbs always end in る in their plain form - hence 'one' level. Each conjugated form is created by replacing the る with the appropriate (standard) ending.
べる (to eat) as an example:

Godan 五段(ごだん)'う' form verbs

The most common five forms of godan verbs use each of the five Japanese vowel sounds (あ, い, う, え, お) - hence 'five' level - combined with whatever consonant begins the final sound of the plain form. Using
く (to write) as an example, the consonant is 'k' (from く):
Vowel soundFormExample
Godan exceptions
A small number of verbs ending in る are godan verbs even though their plain form appears to classify them as ichidan. (In other words,
る becomes
There is no rule which determines whether verbs ending in る are ichidan or godan, so it is best to memorize the exceptions below.
to enter
to run
to need
to return
to limit
to cut
to chatter
to know

irregular verbs - 来る(くる) and する

There are only two key irregular verbs in Japanese: する (to do), and くる (to come). Both are very common - especially する, which can be used to turn any noun into a verb.

する to do

plain formするしない
masu formしますしません
past formしたしなかった
polite past formしましたしませんでした
te formしてしなくて
te stem form
potential formできるできない
passive formされるされない
causative formさせるさせない
causative passive formさせられるさせられない
conditional formすればしなければ
imperative formしろするな
volitional formしよう
The potential form of する is actually an entirely different verb, できる, which is used in its own right to mean 'to be able to'.

る to come

plain formくるこない
masu formきますきません
past formきたこなかった
polite past formきましたきませんでした
te formきてこなくて
potential formこられるこられない
passive formこられるこられない
causative formこさせるこさせない
causative passive formこさせられるこさせられない
conditional formくればこなければ
imperative formこいくるな
volitional formこよう

Other exceptions

In addition to くる and する, one other verb, ある (meaning to be or to have) has two irregular forms - the plain negative (ない) and the plain past negative (なかった). All other forms of ある are regular, and ある is not considered an irregular verb.
