Flying from Paris to Tokyo produces roughly 2,477 kg of CO₂ per passenger, based on the ICAO/EEA short-haul emission factor of ~0.255 kg per passenger-km. The Paris → Sydney flight emits about 4,325 kg. Choosing the shorter route saves approximately 1,848 kg of CO₂ per traveler — equivalent to 88 typical tree-years of carbon sequestration.
The Paris to Tokyo route covers 9,712 km (6,035 miles), crossing from Europe to Asia. Paris (population: 2,161,000) is located in Île-de-France, France, while Tokyo (population: 13,960,000) is in Kanto, Japan.
The Paris to Sydney route covers 16,960 km (10,538 miles), spanning from Europe to Oceania. Paris (population: 2,161,000) is in Île-de-France, France, and Sydney (population: 5,312,163) is in New South Wales, Australia.
Flying from Paris to Tokyo takes approximately 12h 38min, while Paris to Sydney takes 21h 42min. If driving is an option, expect roughly 157h 49min for the first route and 275h 36min for the second.
Since both routes depart from Paris, this comparison is especially useful for travelers deciding between Tokyo and Sydney as a destination.
The 7,248 km difference between these routes is substantial and will significantly impact travel time and cost.
Neither route is practical by car. Flying is the recommended transport for both.
Tokyo (Japan) has a population of 13,960,000 and is located in the Kanto region of Asia. As a major metropolis, it offers extensive international connections and diverse attractions.
Sydney (Australia) has a population of 5,312,163 and is situated in New South Wales, Oceania. This major global city has multiple airports and world-class infrastructure.
Choose this route if your priority is reaching Tokyo (Japan) — a city of 13,960,000 in the Kanto region of Asia. It is also the shorter option at 9,712 km, which translates to a 9h 4min flight-time saving and roughly 1,848 kg less CO₂ per passenger versus the alternative. This is a fly-only route in practice — overland travel is not realistic at 9,712 km. The initial bearing is 33° (NNE), so a great-circle flight leaves Paris heading roughly NNE.
This route is the right call if you are heading to Sydney (Australia) — a city of 5,312,163 in the New South Wales region of Oceania. Even though it is the longer route at 16,960 km, it remains the obvious pick when Sydney is the actual destination, when departure schedules from Paris are more convenient, or when fares undercut the alternative. Overland travel is not practical for 16,960 km; flying is the realistic mode. Departing Paris, the great-circle bearing toward Sydney is 69° (ENE).
Paris (48.86°, 2.35°) and Tokyo (35.68°, 139.65°) sit with a time-zone shift of +9 hours. Paris (48.86°, 2.35°) and Sydney (-33.87°, 151.21°) have a +10-hour offset. Routes with time-zone shifts of 5 hours or more typically produce noticeable jet lag — plan one recovery day per three time zones crossed.
Tokyo is closer at 9,712 km, which is 7,248 km (43%) shorter.
9,712 km (6,035 miles). Flight: ~12h 38min.

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.
