Most journeys from Thailand to Japan connect through Singapore Changi Airport, which is designed for easy and enjoyable transits. For longer layovers, you can join an official free transit tour into the city, subject to eligibility and timing, or explore the airport's themed gardens, walking paths, and art installations. Shorter layovers are well spent airside, where you can enjoy quiet rest areas, showers, playgrounds, and a wide choice of dining and retail options without leaving the terminal. Your time at the airport is more than just a wait — it is an integral part of your journey.

Yes, your baggage will typically be checked through to your final destination in Japan 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 Japan, 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.

Thailand observes Indochina Time (UTC+7) all year without daylight saving, so Bangkok and Phuket share the same time. Japan uses Japan Standard Time (UTC+9) with no daylight saving, meaning cities such as Tokyo, Osaka, Nagoya, and Fukuoka are typically 2 hours ahead of Thailand throughout the year. This consistent two-hour difference makes it easier to plan flight arrivals, onward connections, and daily activities.
