Translation guide
In English, "bleachers" refers to tiered, often uncovered seating for spectators, typically at sports events. In Japanese, there is no single exact equivalent; the best translation depends on the context and type of seating.
bleachers (general)

Describing the portable, often wooden or metal tiered seating set up temporarily for events.

There is no single Japanese word that perfectly matches 'bleachers'. Using スタンド is usually safe, but be aware that it can also mean 'grandstand' or 'covered stand'. If you need to emphasize the uncovered, bench-like nature, add a description like 屋根のない (roofless) or ベンチ席 (bench seats).
