Distance guide covering 43+ routes across 6 cities in Japan. Includes domestic and international connections with flight times and driving distances.
Japan is home to 6 major cities in our database, including Tokyo, Osaka, Nagoya, Sapporo, Fukuoka and more. The largest city by population is Tokyo with approximately 13,960,000 residents, located in the Kanto region.
Within Japan, there are 9 domestic routes connecting cities across the country. The shortest domestic route is Kyoto to Osaka at 43 km, while the longest is Sapporo to Osaka at 1,059 km.
Japan also connects to 34 international destinations worldwide. Whether you're planning domestic travel or international flights, this comprehensive distance guide provides all the information you need. All distances are calculated using the Haversine formula for maximum accuracy.
For travelers within Japan, shorter routes under 500 km are often well-suited for driving or train travel. Routes between 500-2,000 km offer a choice between driving and flying, while anything over 2,000 km is typically best served by air travel.

Japan's aviation and ground network shapes how the 43 routes on this page actually feel in practice. The flag carrier Japan Airlines handles most long-haul departures, while low-cost players such as Peach, Jetstar Japan, Spring Airlines Japan dominate short-haul leisure traffic. The primary international gateway is Tokyo Haneda (HND) and Narita (NRT), which also acts as the natural connection point for travelers using one-stop routings to save 20–40% on long-haul fares.
For shorter trips, ground transport in Japan is built around the JR Shinkansen bullet train network — Tokyo to Osaka in 2h 22min on the Nozomi. On corridors under roughly 700 km, door-to-door rail travel is often faster than flying once airport security and transfers are factored in — a calculation worth running before booking domestic flights inside Japan.
Of the 43 routes covered here, the breakdown is 7 under 500 km, 11 between 500 and 1,500 km, 11 between 1,500 and 5,000 km, 13 between 5,000 and 10,000 km, 1 over 10,000 km. That mix is why a single travel-time rule never works for Japan: a typical traveler will encounter everything from a 60-minute regional hop to a 12-hour ultra-long-haul flight, depending on destination.
The 6 cities in our database for Japan are anchored by Tokyo — a metropolitan area of roughly 13.96 million people sitting at 35.68°N, 139.65°E. That position places much of Japan in a temperate climate with four distinct seasons, which directly influences both the local travel calendar and how comfortable arrivals from very different latitudes will feel.
Domestic distances within Japan range from Kyoto to Osaka at 43 km up to Sapporo to Osaka at 1,059 km. The wider that range, the more critical it becomes to match transport mode to journey length — exactly what the routes table above is designed to help with.
Because of Earth's curvature, the great-circle distances shown on this page are not the same as flight paths drawn on a flat map. Routes between Japan and far-away destinations often track closer to the poles than people expect — read more in our guide on how the Haversine formula works.
Japan is generally a higher-cost destination, so booking 2–3 months ahead for international flights and 6–8 weeks ahead for domestic routes typically delivers the best fares.
Mid-week departures (Tuesday and Wednesday in particular) into and out of Japan are typically 20–30% cheaper than Friday and Sunday flights on the same routes. Red-eye and very early-morning departures usually save another 10–15%. Budget carriers serving Japan apply strict carry-on rules and unbundled fares, so packing light remains the single biggest lever for keeping total trip cost low.
For multi-city trips inside Japan, compare the cost of a single open-jaw flight plus ground transport against multiple point-to-point flights — on routes with strong rail service, the rail-and-fly combination usually wins on both price and total door-to-door time.
Under 500 km: ground transport — driving, coaches, or the rail services described above — is usually competitive with flying door-to-door once airport overhead is included. This band covers many of the shortest routes on this page.
500–1,500 km: the choice gets interesting. A direct domestic flight typically saves 2–4 hours over driving in this band, but cheap fares disappear quickly without advance booking.
Over 1,500 km: flying becomes the obvious choice. The 34 international routes from Japan above 1,500 km on this page are essentially flight-only journeys; ground alternatives exist only on a handful of specialist sleeper trains or long-distance coaches and aren't time-competitive.
Whichever mode you pick, use the calculator on this site to confirm exact great-circle figures, then add 20–40% for actual driving distance and 30–60 minutes per direction for airport overhead.

All distances use the Haversine formula for great-circle distance — the shortest path between two points on Earth. Flight times assume 800 km/h cruising speed plus 30 minutes for takeoff/landing. Driving times use 80 km/h average with a 30% road routing factor.
