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.
名探偵の事件簿を読んだ。
I read the casebook of the great detective.
この事件簿には過去の未解決事件が記録されている。
This casebook contains records of past unsolved cases.
警察は事件簿を見直して、犯人の手口に共通点がないか調べた。
The police reviewed the case files to check whether the perpetrator's methods had anything in common.
Composed of 事件 (incident, case) and 簿 (register, book of records). The suffix 簿 appears in many record-keeping compounds such as 帳簿 (account book) and 名簿 (name list). Very commonly seen as a title element in Japanese mystery fiction and detective shows.
COMMON COLLOCATIONS:
- 事件簿を調べる: to examine the case files
- 事件簿に載る: to be recorded in the casebook
- 未解決事件簿: cold case files
CULTURAL NOTE:
The word is widely recognized from manga and anime titles like 金田一少年の事件簿 (The Kindaichi Case Files), making it familiar even to people who do not work in law or investigation.
