NEW We regularly add new articles on grammar and other points of interest, and add more material to existing articles. Use these links to see what's been added or updated recently:
NEW Track your knowledge of grammar points using a 'mastery score' for each grammar point. Mastery scores will be updated automatically as you study grammar flashcards, and you can edit them manually from your mastery summary or from a grammar point. You can view a summary of your mastery of grammar points by usefulness or JLPT level.
Grammar points are referenced by the JLPT level they are first used in, so you can search for all grammar points in a specific level of the JLPT. Use the syntax jltp:x where x is the level of JLPT (from 5, the lowest/easiest, through to 1, the highest/hardest).
NEW You can also combine searches for a specific grammar point or type of grammar point with a JLPT level by adding jlpt:x to any search:
You can also search for grammar points by Kanshudo's rating of how useful they are to you. Grammar points have usefulness levels from 1 to 6. In general, grammar with a JLPT tag will have equivalent usefulness (usefulness 1 corresponds to JLPT 5, and 5 corresponds to JLPT 1; usefulnesss 6 is for harder / rarer grammar points). Some grammar points have a Kanshudo usefulness rating but no JLPT rating because they do not appear in standard JLPT lists, but you would be expected to know them when your Japanese is at that level.

Our library also contains a number of articles on quirks of Japanese grammar, pronunciation, how grammar came to be the way it is, as well as Japanese culture and language more generally.

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.
To find the kanji :
  • 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.
