About time in Koshigaya

Koshigaya keeps Japan Standard Time, UTC+9 from UTC all year. The offset never changes, so any difference between you and Koshigaya moves only when your own clocks do.

Koshigaya shares the zone Asia/Tokyo with Tokyo, Yokohama, Osaka, Nagoya, so a time here is also the time there. One canonical page per zone keeps the difference honest: the settlement name changes, the clock does not.

Offsets and daylight saving rules come from the IANA time zone database — see IANA time zone notes for what that data does and does not promise about future dates.
