筆順 · the shared opening
Openings and endings
How many jōyō characters share the first strokes of a kvg:type sequence, and how many share the last.
These are frequencies in one KanjiVG snapshot. They are not a rule that a character must open or end with a given type.
This page counts shared prefixes and suffixes of the letter-stripped sequence. The stroke-type inventory counts each written string, and where that one stroke sits in the order. The stroke-direction atlas counts where a stroke starts, and which way it runs.
Cinnabar marks the shared strokes named in that plate’s caption. Click a plate to replay. With reduced motion the finished character stays still, and the mark stays.

What is counted
- The sequence
- The kvg:type of each stroke, in stroke order, after a trailing letter is deleted. A slash stays.
- Opening
- The first 1, 2, or 3 strings. A character is counted at a length only when it has at least that many strokes.
- Ending
- The last 1, 2, or 3 strings, kept in the order they are written. The same length rule applies.
- Branching factor
- How many distinct strings extend a node. For an opening, the extension is the next stroke. For an ending, the extension is the stroke written immediately before. A node whose characters all have that exact length has branching factor 0. At length 1 the parent is the whole list.
- Stops here
- Characters whose stroke count equals the length of the node. A one-stroke character is an opening of length 1 and an ending of length 1, and it is absent from lengths 2 and 3.

Largest shared endings
The largest ending at a length is the one shared by the most characters. The sequence is the last strokes in the order they are written. The plates mark those strokes.

Characters that share them
Cinnabar marks the shared ending. Under one sequence, the characters are the shortest that are longer than the ending. A character already drawn for another ending on this page is skipped.
The count is every jōyō character with that ending. The plates are only the shortest few.
