        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "A nonstop flight from Seoul (ICN) to Tokyo (NRT) typically takes about 2 hours 10 minutes to 2 hours 30 minutes. The return flight from Tokyo to Seoul is often slightly shorter, around 2 hours 5 minutes to 2 hours 25 minutes, due to prevailing winds. Flights with one stop, commonly via Osaka or Fukuoka, can extend total travel time to 4–6 hours or more. Korean Air, Asiana, and Japanese carriers offer similar nonstop durations."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "Yes, there are plenty of direct flights from Seoul Incheon (ICN) to Tokyo Narita (NRT). Twelve airlines operate non‑stop on this route — Korean Air, Asiana, Jin Air, Jeju Air, T'way Air, Eastar Jet, Air Seoul, Air Busan, Ethiopian Airlines, Zipair Tokyo, Thai Vietjet Air, and Air Premia — with most carriers running daily service and Ethiopian and Air Premia flying six days a week (no Tuesday flights). Combined they offer over 250 weekly non‑stop flights, so you'll have departures throughout the day essentially every day.",
        "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports.",

        "question": "Are there visa requirements to travel from Seoul to Tokyo?",
        "answer": "Yes, there are visa requirements for travel from Seoul to Tokyo, depending on your nationality. If you are a South Korean citizen, you can enter Japan for short-term stays (typically up to 90 days) without a visa for tourism or business. If you are a Japanese citizen, you can enter South Korea visa-free for short stays. For nationals of other countries, a visa may be required. Always check the latest requirements based on your passport before travel."

      "q3": {
        "question": "What are the ground transportation options in Tokyo?",
        "answer": "From Narita Airport to central Tokyo, mass transit is the most used and efficient choice. The Narita Express (N'EX) train reaches Tokyo Station in about fifty-three minutes, while the Keisei Skyliner goes to Ueno Station in forty-one minutes, both offering fast, comfortable, and reliable service. Slower but cheaper options include the Keisei Main Line limited express and the JR Sobu Line rapid trains, taking roughly eighty to ninety minutes. Airport limousine buses serve major hotels and districts in about sixty to ninety minutes but are subject to traffic delays. Taxis are available but extremely expensive, costing over ¥20,000 and taking a similar time. Ride-share services are limited and not a primary option. Car rentals are impractical for city travel due to high costs and congestion. Most travelers use the N'EX or Skyliner for their speed and convenience."

        "question": "Are overnight (red‑eye) flights available from Seoul to Tokyo?",
        "answer": "No overnight (red-eye) flights are available on the nonstop Seoul (ICN) to Tokyo (NRT) route, and no connecting itineraries with a red-eye long leg were found either.",
        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",
