A continuous stretch of land or space.
一帯 refers to a broad, continuous stretch of land or geographical area. It often follows a place name or location word to mean "the whole area around ~."
COMMON PATTERNS:
- この一帯: this (whole) area
- 海岸一帯: the entire coastal area
- 駅周辺一帯: the whole area around the station
- 一帯に広がる: to spread across the area
HOMOPHONE NOTE:
Different from 一体 (what on earth; one body) — same reading but different kanji and completely different meaning. 一帯 is always geographical.
