The 5,282 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.
London (United Kingdom) has a population of 8,982,000 and is situated in England, Europe. 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. Despite being the longer of the two at 10,852 km, it makes sense when Tokyo 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 10,852 km. The initial bearing is 333° (NNW), so a great-circle flight leaves New York heading roughly NNW.
This route is the right call if you are heading to London (United Kingdom) — a city of 8,982,000 in the England region of Europe. It is also the shorter of the two at 5,570 km, saving about 6h 36min of flying and around 1,347 kg of CO₂ per passenger. Overland travel is not practical for 5,570 km; flying is the realistic mode. Departing New York, the great-circle bearing toward London is 51° (NE).
New York (40.71°, -74.01°) and Tokyo (35.68°, 139.65°) sit with a time-zone shift of +14 hours. New York (40.71°, -74.01°) and London (51.51°, -0.13°) have a +5-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.
London is closer at 5,570 km, which is 5,282 km (49%) shorter.
10,852 km (6,743 miles). Flight: ~14h 4min.

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.
