Japan's domestic flight network is extensive, competitive, and often surprisingly cheap. While the Shinkansen dominates short-to-medium distances, flying becomes the smarter choice for routes over 600 km where trains take 4+ hours. Budget carriers have transformed Japanese domestic travel with fares sometimes cheaper than a Shinkansen ticket for routes that would take triple the time by train.
This guide covers when to fly versus when to take the train, which airlines to use, how to find the cheapest fares, and the special tourist discount fares that most visitors do not know about.

ANA Discover Japan Fare
💡
Tourist-Only Discount: ANA Discover Japan
ANA offers a special "Discover Japan" fare exclusively for foreign visitors with a non-Japanese passport.

The Door-to-Door Reality
True Travel Time: Flight vs Shinkansen
Domestic Flight (Door-to-Door)
Travel to airport: 30-90 min
Check-in & security: 30-60 min
Flight time: 1-3 hours
Baggage claim: 15-20 min
Airport to city: 30-90 min
Total: 3-7 hours depending on route
Shinkansen (Door-to-Door)
Walk to station: 10-20 min
No check-in or security
Train time: 1-5 hours
Walk off train at city center
Total: Train time + 30 min
City center to city center
Flying only wins when the flight saves 2+ hours over the train. For Tokyo-Osaka (2h30 by train), flying is slower door-to-door. For Tokyo-Sapporo (8h by train), flying saves 4+ hours.
How to Find Cheap Domestic Flights
💰
Booking the Best Fares
1
Use Google Flights or Skyscanner
Compare all airlines at once. Skyscanner often shows the lowest LCC fares. Google Flights has a flexible date calendar that shows the cheapest days to fly.
2
Check airline websites directly
Peach and Jetstar often run sales not indexed by comparison sites. Check flypeach.com and jetstar.com/jp for flash sales with fares as low as ¥1,000-3,000. ANA's Discover Japan page is also direct-only.
3
Book 1-3 months ahead
Best fares appear 30-90 days before departure. Same-day and last-minute domestic flights are expensive (¥20,000-40,000+). Planning ahead is essential for budget flights.
4
Fly on weekdays
Tuesday and Wednesday flights are cheapest. Avoid Friday evening and Sunday afternoon flights which carry a premium. Morning flights are often cheaper than evening departures.
5
Consider Skymark Airlines
Mid-range carrier flying from Haneda at prices between LCC and full-service. Good legroom, no frills charge for checked bags. Strong Tokyo-Fukuoka and Tokyo-Kobe routes.

Domestic Flight FAQ
Should I fly or take the train from Tokyo to Osaka?
+
Take the Shinkansen. It takes 2h30m city-center to city-center with no airport overhead. A flight takes about 1h15m in the air but 4-5 hours door-to-door including transfers and check-in. The Shinkansen is more convenient, more frequent (every 10 min), and often comparable in price.
Which airports do budget airlines use?
+
Peach and Jetstar primarily use Narita (not Haneda) in Tokyo and Kansai in Osaka. Spring Japan uses Narita only. This matters because Narita is 60-90 minutes from central Tokyo. Factor in airport transfer time and cost when comparing with Shinkansen. ANA and JAL fly from the more convenient Haneda.
Can I use my JR Pass on domestic flights?
+
No. The JR Pass covers only rail and some JR buses. However, for long routes like Tokyo-Sapporo where flying is clearly better, you can use the JR Pass for other legs and buy a separate flight for the long-distance portion.
Is it safe to book budget airlines in Japan?
+
Absolutely. Peach and Jetstar Japan have excellent safety records. Japan has strict aviation safety standards. LCC service is no-frills (pay for bags, food, seat selection) but the safety is identical to ANA and JAL.
