Booking Strategy
For Tokyo to Seoul flights, the sweet spot for booking is 3-5 weeks before departure, especially for budget carriers like Peach and T’way where last-minute prices can double. February offers the lowest fares (avg €310), while July peaks at €400. Tuesday and Wednesday departures are consistently €30-50 cheaper than Friday-Sunday. For Haneda departures (HND-GMP), prices are typically €20-40 higher than Narita (NRT-ICN) but save time getting to/from central Tokyo. Use Skyscanner’s ‘Everywhere’ search to identify cheapest travel dates, then book directly with the airline to avoid OTA booking fees. Korean low-cost carriers (T’way, Jin Air) often have the best prices but check baggage policies carefully – hidden fees can make them more expensive than full-service carriers. If flying from Narita, consider the ¥2,500 Narita Express train vs. budget bus (¥1,000) when calculating total trip cost.
Route Tips
- Haneda (HND) to Gimpo (GMP) flights are shorter (2h 30m) and closer to central Seoul, but Narita (NRT) to Incheon (ICN) often has cheaper flights – factor in the 1+ hour train ride from Incheon to downtown when comparing total travel time.
- South Korea now offers visa-free entry for Japanese passport holders for stays up to 90 days – no advance visa needed. Bring only your passport.
- If flying into Incheon (ICN) and staying in Hongdae or Sinchon area, consider the airport limousine bus (Line 6002) – it’s direct, costs around ₩10,000 (€7), and takes 50-60 minutes.
- Korean low-cost carriers (T’way, Jin Air, Air Busan) often have the lowest prices but check if they depart from Gimpo or Incheon – Gimpo is much more convenient for Seoul.
- Book directly on airline websites rather than through OTAs – carriers like Peach and T’way sometimes offer better deals or additional baggage options on their own sites, and you’ll have easier customer service if issues arise.
