Time in Hiroshima, Japan

Time zone: JST (UTC/GMT +09:00) — Asia/Tokyo

Hiroshima keeps JST (9 hours ahead of UTC, UTC+09:00). Its database zone is Asia/Tokyo — worth knowing if you are scheduling anything that has to survive a daylight saving change.

There is no daylight saving in Hiroshima. UTC+09:00 applies all year, so the offset never moves on this side — only the other party's clock changes.

Current gap between Hiroshima and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

No shared working window exists with New York, Los Angeles, London or Sao Paulo, so those calls have to sit outside somebody's normal hours.

Same zone, same time — each of these sits on Asia/Tokyo alongside Hiroshima, including through any clock change.
