Time difference & DST
Japan Standard Time is 17 hours ahead of Pacific Standard Time, dropping to 16 hours when California is on daylight saving time. This is the pairing that connects US West Coast tech and entertainment companies with partners in Tokyo, Osaka, and beyond.
Japan does not use daylight saving time, so JST is a constant UTC+9. When California moves to PDT the effective offset shrinks by an hour — worth noting for automated scheduling tools.
Best time to schedule a call
The most comfortable window is a Pacific afternoon / Tokyo morning meeting: 4:00 PM PST maps to 9:00 AM JST the next day, keeping both sides inside standard office hours.
