        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "A direct flight from Seoul (ICN) to Tokyo (HND) typically takes about 2 hours and 20 minutes. The return flight from Tokyo to Seoul is often slightly shorter at around 2 hours and 10 minutes due to prevailing tailwinds. Most carriers offer similar flight times, with Korean Air and Asiana Airlines providing frequent nonstop service. Layover flights are uncommon on this short route, but if connecting through cities like Busan or Osaka, total travel time can extend to 5 hours or more."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "Yes, there are non‑stop flights from Seoul (ICN) to Tokyo (HND) on Korean Air, Asiana Airlines, and Peach Aviation — all three operate daily. Korean Air runs two daily departures (around 8:30–8:40 PM), Asiana also has two daily (around 9:10–9:30 PM), and Peach offers one daily departure (around 10:35 PM).",
        "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. Carrier service and weekly frequencies are summarized from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

        "question": "Are there visa requirements to travel from Seoul to Tokyo?",
        "answer": "Yes, visa requirements depend on nationality. South Korean citizens can enter Japan visa‑free for short stays (typically up to 90 days for tourism or business) under a reciprocal visa exemption. Japanese citizens also enjoy visa‑free travel to South Korea for short stays. Travelers of other nationalities must check Japan’s visa policy: many countries have visa‑waiver arrangements, but others require a visa obtained in advance. Always verify current rules before travel, as requirements can change."

        "question": "What are the ground transportation options in Tokyo?",
        "answer": "From Haneda Airport (HND), you can reach central Tokyo via the Tokyo Monorail, which connects to Hamamatsucho Station in about fifteen to twenty minutes, or the Keikyu Line, which reaches Shinagawa Station in roughly ten to fifteen minutes. Both offer seamless transfers to the JR Yamanote Line and the wider rail network. Limousine buses serve major hotels and neighborhoods in sixty to ninety minutes, while taxis and ride-share services take thirty to sixty minutes depending on traffic but are expensive. Car rentals are available but impractical for city travel due to congestion and parking costs. The Keikyu Line is most used for its speed and direct access to key transit hubs."
