PST is 17 h behind JST (16 h during PDT). No daytime overlap — 9 AM PT = 2 AM JST next day. Meeting scheduling collapses to 5 PM PT (10 AM JST next day) or 6 PM PT (11 AM JST) as the least-bad options. Japanese semiconductor and automotive companies with US West Coast R&D engineering typically accept 3-hour weekly evening blocks for cross-timezone leadership reviews.
US West Coast — home of Silicon Valley, LA entertainment, and the SaaS / VC ecosystem. Business hours 9 AM – 6 PM PT. Startup / tech culture stretches later than East Coast: it's common for calendar invites from West Coast product teams to run through 8 PM PT.
Japan — one of the few large economies that has no DST, so JST is JST year-round (UTC+9). Business hours 9 AM – 6 PM JST with strong presence-based culture (staying past 7 PM is common). Same offset as Korean Standard Time (KST).
Time gap: JST is 17.0 hours ahead of PST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
PST to JST is one of the more useful timezone conversions for calls, deadlines, and travel planning. The current gap is 17 hours, which means 9:00 AM PST becomes 2:00 AM (next day) JST and 2:00 PM PST becomes 7:00 AM (next day) JST.
This matters when teams in Los Angeles and Tokyo need to align business hours, webinars, or customer-support coverage. Use the chart on this page when you want the exact conversion for today instead of relying on manual offset math.
Daylight saving changes can also shift the gap during the year, so a converter is safer than memorizing a fixed difference. That is especially important for recurring meetings and date-sensitive handoffs.
