Our free PST to JST converter instantly translates US Pacific Time into Japan Standard Time — the Los-Angeles-to-Tokyo conversion. Japan is well into the next day relative to the West Coast, so this tool makes the 17-hour gap and the date rollover clear at a glance.
Japan is far ahead of the US West Coast, and since Japan has no daylight saving, the US side drives any seasonal change: (Offsets follow the IANA Time Zone Database.)
JST is 17 hours ahead of PST during US standard time and 16 hours ahead when the West Coast is on PDT. So 9:00 AM PST is 2:00 AM JST the next day in winter.
Los Angeles late afternoon (4:00–6:00 PM PST) lines up with Tokyo morning (9:00–11:00 AM JST the next day). That is the most practical overlap given the 17-hour gap.
Because Japan is 16–17 hours ahead, most West Coast times fall on the next calendar day in Tokyo. The converter shows the correct date on both sides so you do not book a meeting a day off.
JST is 17 hours ahead of PST, shifting by an hour around daylight-saving changes. 100% free, no registration, and fully private — every conversion happens in your browser.
Uses the IANA database for America/Los_Angeles and Asia/Tokyo, so daylight saving is applied automatically — no manual offset math.
Convert PST to JST the moment you pick a time. No signup, no ads in your way, nothing to install.
Spot the wide 17 hours gap between Los Angeles and Tokyo so you can plan async or off-hours calls.
Every conversion runs locally in your browser using your device clock. Your dates and times never touch a server.
