Most journeys from Japan to San Francisco connect through Singapore Changi Airport, which offers abundant ways to spend your time. For longer layovers, you can explore themed gardens, rest areas, and, when available, join a free transit tour to see highlights of Singapore. For shorter stops, stay airside to enjoy lounges, showers, dining options, and shopping spread across the terminals. Your time at the airport is more than just a wait — it is an integral part of your journey.

Tokyo, Osaka, Nagoya, and Fukuoka all share Japan Standard Time (UTC+9) with no daylight saving. San Francisco observes Pacific Time, which is typically UTC‑8 in winter and UTC‑7 in summer. This means San Francisco is usually 17 hours behind Japan during Northern Hemisphere winter, and 16 hours behind during daylight saving time, roughly March to early November.

Yes, your baggage will typically be checked through to San Francisco when flying via the layover airport on a single booking with Singapore Airlines, provided both flight segments are under the same booking reference (PNR), the connection is under 24 hours, and, for partner-operated onward flights, a through-check agreement is in place.

You may be able to plan a stopover at the layover city on your journey to San Francisco, subject to your ticket conditions and availability. When booking, you can search for multi-city options or speak with our customer service team or your travel agent, who can advise whether a stopover can be added to your itinerary.
