jykanji

Jyokanji is a term that refers to a type of Japanese kanji that are particularly difficult or obscure. These characters are often not found in common use and may appear in older texts, specialized fields, or as part of personal names. The difficulty of kanji can stem from several factors, including the number of strokes, the complexity of their components, or their rarity.

While the exact definition of "jyokanji" can be subjective, it generally encompasses characters that are not part of the standard Joyo kanji list, which comprises 2,136 characters taught in Japanese schools. Some jyokanji might have multiple readings or obscure meanings, making them challenging to learn and use. Their existence highlights the vastness and historical depth of the Japanese writing system.

Encountering jyokanji typically occurs when reading historical documents, specialized academic papers, or when deciphering uncommon personal names. For learners of Japanese, these characters often represent a significant hurdle beyond the common vocabulary. Their study is usually reserved for advanced students or those with specific research interests.
