じけんぼ

noun

casebook; case file; record of incidents

1. casebook; case file; record of incidents

A book or record documenting cases, incidents, or investigations. Used both for actual case records in legal and investigative contexts, and as a title format for mystery fiction and TV shows.

Composed of 事件(じけん) (incident, case) and 簿(ぼ) (register, book of records). The suffix 簿(ぼ) appears in many record-keeping compounds such as 帳簿(ちょうぼ) (account book) and 名簿(めいぼ) (name list). Very commonly seen as a title element in Japanese mystery fiction and detective shows.
