About
This resource details the official list of Jôyô kanji, which are the common-use characters designated by the Japanese Ministry of Education that every adult citizen is expected to master. It serves as a foundational reference for anyone engaging in language study and is a critical tool for understanding the standardized Japanese writing system.
Columns
The dataset contains seven distinct fields:
- ID: A numerical identifier assigned to the specific kanji character.
- new: The kanji character in its modern shinjitai form, following the revision adopted in 1946.
- old: The kanji in its older kyûjita form, present only when it differs from the modern shinjitai version. Note that this field has missing values for 83% of the entries.
- radical: The defining radical of the kanji, which is the component used for character classification in traditional dictionaries.
- strokes: The total number of strokes required to correctly write the kanji, with values ranging from 1 to 29.
- grade: The educational grade level in which the kanji is taught in Japanese Elementary schools (Grades 1 through 6). Characters taught in secondary school are designated with 'S,' which is the most frequent value.
- year_added: The specific year the kanji was officially added to the list, applied only if the addition occurred after the original 1946 designation. This field is absent for 86% of the records.
