department; division; section; category
A distinct section or branch within an organization, field, or system of classification. Used for organizational units in companies and also for categories in competitions or awards.

部門 is used for organizational divisions within companies and institutions, as well as for categories in competitions, awards, and classifications.
COMMON COLLOCATIONS:
- 営業部門 (sales department)
- 製造部門 (manufacturing division)
- 研究部門 (research division)
- 部門別 (by department/category)
- 部門長 (department head)
In awards contexts, 部門 corresponds to English "category" — for example, 主演女優部門 (Best Actress category). Distinct from 部署 (section, post), which focuses more on the specific workplace assignment, and 課 (section, division), which is a more specific organizational unit within a larger department.
