日誌(にっし)

にっし
noun
daily log; journal; diary (official record)
1. daily log; journal; diary (official record)
A record of events, activities, or observations kept on a daily basis, typically in a professional, institutional, or organizational context. Unlike a personal diary, a 日誌(にっし) is usually an official or work-related record.

Composed of 日(にっ) (day) and 誌(し) (record, chronicle). The word emphasizes systematic, daily record-keeping in a professional or institutional setting. It is distinct from 日記(にっき) (personal diary), which is more private and reflective.

Various types of 日誌(にっし) are standard practice in Japanese workplaces and institutions: 業務(ぎょうむ)日誌(にっし) (work log), 保育(ほいく)日誌(にっし) (childcare log at nurseries), 航海(こうかい)日誌(にっし) (ship's log), and 学級(がっきゅう)日誌(にっし) (class diary, kept by students on rotation).
