The 2,515 km difference between these routes is substantial and will significantly impact travel time and cost.
Neither route has a road figure we can defend. There is no continuous road connection between Tokyo and Sydney — the two cities sit on separate landmasses, so the journey requires air or sea transport. There is no continuous road connection between Tokyo and Singapore — the two cities sit on separate landmasses, so the journey requires air or sea transport.
Sydney (Australia) has a population of 5,312,163 and is located in the New South Wales region of Oceania. As a major metropolis, it offers extensive international connections and diverse attractions.
Singapore (Singapore) has a population of 5,850,342 and is situated in Singapore, Asia. This major global city has multiple airports and world-class infrastructure.
Choose this route if your priority is reaching Sydney (Australia) — a city of 5,312,163 in the New South Wales region of Oceania. Despite being the longer of the two at 7,826 km, it makes sense when Sydney itself is the destination, the schedule fits better, or ticket prices are noticeably lower. This is a fly-only route in practice — overland travel is not realistic at 7,826 km. The initial bearing is 170° (S), so a great-circle flight leaves Tokyo heading roughly S.
This route is the right call if you are heading to Singapore (Singapore) — a city of 5,850,342 in the Singapore region of Asia. It is also the shorter of the two at 5,311 km, saving about 3h 9min of flying and around 642 kg of CO₂ per passenger. Overland travel is not practical for 5,311 km; flying is the realistic mode. Departing Tokyo, the great-circle bearing toward Singapore is 232° (SW).
Tokyo (35.68°, 139.65°) → Sydney (-33.87°, 151.21°): Tokyo keeps Asia/Tokyo time and Sydney keeps Australia/Sydney time — a gap of about 2 hours, with Sydney ahead. The exact gap moves when either zone switches to or from daylight saving, so use the live figure in the calculator for your travel dates. Tokyo (35.68°, 139.65°) → Singapore (1.35°, 103.82°): Tokyo keeps Asia/Tokyo time and Singapore keeps Asia/Singapore time — a gap of about 1 hour, with Singapore behind. The exact gap moves when either zone switches to or from daylight saving, so use the live figure in the calculator for your travel dates. Both gaps come from the cities' real IANA zones and move with daylight saving. Both routes have manageable shifts, so jet lag should not be a major factor.

All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
