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

Grammar detail: 連濁(れんだく)

連濁(れんだく) - voicing of first consonant in second part of a compound word

LOG IN to view grammar mastery data
Often when two words or kanji are combined to make a new word, the first consonant of the second item will be changed from unvoiced to voiced. This concept is known as rendaku, or sometimes 'sequential voicing'.
'Voicing' of a consonant refers to the idea of making the sound by obstructing airflow in your throat. For example, 'k' is unvoiced (the sound is made in the back of the mouth), and 'g' is the voiced version (the sound comes from the throat).
For example:
  • k becomes g, as in
    ものごころ
    物心
  • s becomes z, as in
    あおぞら
    青空
  • t becomes d, as in
    ときどき
    時々
  • h becomes b, as in
    ひとびと
    人々
    , or sometimes p or even pp, as in
    きっ
    ぱら
There are some situations where the second word is left unchanged. For example:
  • Gairaigo (loan words) do not change, as in アイス + コーヒー = アイスコーヒー
  • When the second word already contains a voiced consonant, as in
    やまかじ
    山火事
    (mountain fire), or
    たぬきそば
    狸蕎麦
    . This is known as Lyman's Law
  • When the word is of entirely Japanese origin, as in
    ほあんけんさ
    保安検査
    (safety inspection), or
    よこはま
    横浜
  • When the compound word means A and B together, rather than A's B. So for example 山川 would be read やまがわ when it refers to 'a mountain river', but as やまかわ when it refers to 'mountains and rivers' (actually with this meaning it is more commonly read さんせん to avoid confusion)
  • When the second word is already a compound word
  • Certain specific kanji tend not to be voiced. For example, in
    わるくち
    悪口
    ,
    ひとくち
    一口
    , and
    むくち
    無口
    , the 口 remains くち
