Time in Kōriyama, Japan

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

Kōriyama runs on JST. That places it 9 hours ahead of UTC (UTC+09:00); in a calendar, server config or booking form, select Asia/Tokyo.

Kōriyama does not change its clocks. The same UTC+09:00 offset holds in January and July, which makes it a stable anchor for recurring calls.

Around 322,996 people live in Kōriyama, making it the 52nd largest of the 208 Japan cities covered here.

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

Assuming a 09:00–17:00 day at both ends, these windows (in Kōriyama local time) fall inside working hours for both cities.

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.

These Japan cities also use Asia/Tokyo, so their clocks read identically to Kōriyama at every moment of the year.
