Japan Standard Time stays at UTC+9
Tokyo currently uses Japan Standard Time year-round, with no daylight-saving adjustment. Osaka and Kyoto share that time. Seoul also has the same present-day UTC+9 offset, despite using a different IANA time-zone identifier.
Tokyo is far enough ahead of North America that a morning meeting can belong to the previous evening there. US daylight saving changes the difference even though Tokyo's clock stays fixed. Always include both the destination time and destination date in an invitation.
