        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "A nonstop flight from Seoul Incheon (ICN) to Tokyo (Narita NRT or Haneda HND) typically takes about 2 hours 30 minutes. The return flight from Tokyo to Seoul is slightly shorter at around 2 hours 10 minutes due to favorable tailwinds. Nonstop service is widely available on Korean Air, Asiana, ANA, and JAL, making connecting flights unnecessary on this busy route."

      "q1": {
        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "{\"answer\": \"Yes, there are abundant nonstop flights from Seoul Incheon (ICN) to Tokyo — both Narita (NRT) and Haneda (HND) — with well over a dozen airlines operating daily service, including Korean Air (KE), Asiana (OZ), Jeju Air (7C), Jin Air (LJ), T'way (TW), Air Seoul (RS), and more. Combined, these carriers run hundreds of nonstop flights per week, making this one of the most heavily served international routes in Asia, with departures spread throughout the day from early morning to late night.\", \"relevant\": true,\"toolsUsed\":[\"route_airlines\"]}"

        "question": "Are there visa requirements to travel from Seoul to Tokyo?",
        "answer": "Visa requirements depend on your nationality. South Korean nationals can visit Japan visa-free for up to 90 days for tourism or business. US nationals and most Western passport holders also enjoy visa-free entry to Japan for short stays. Japanese nationals traveling to South Korea can enter visa-free for up to 90 days. Some nationalities do require a visa to enter Japan, so check with the Japanese embassy or consulate for your specific passport before travel."

      "q3": {
        "question": "What are the ground transportation options in Tokyo?",
        "answer": "Tokyo is served by two main airports, Narita and Haneda. From Narita, the Narita Express (N'EX) reaches Shinjuku or Tokyo Station in about sixty to ninety minutes and is the most popular option for international arrivals. The Keisei Skyliner reaches Ueno in roughly forty minutes and is slightly cheaper. Limousine buses connect Narita to major hotels across the city in ninety minutes or more depending on traffic. From Haneda, the Tokyo Monorail reaches Hamamatsucho in about twenty minutes, and the Keikyu Line connects to central stations in a similar time. Taxis from either airport are expensive and slow in traffic. Ride-share services are limited in Japan compared to other countries. Car rentals are available but driving in central Tokyo is impractical. Most travelers use the N'EX from Narita or the monorail and Keikyu Line from Haneda for their reliability and speed."

        "question": "If I need a connection, what are common layover cities between Seoul and Tokyo?",
        "answer": "Seoul to Tokyo is a short 2 to 3 hour route with abundant non-stop flights on Korean Air, Asiana, ANA and JAL, making connections unnecessary. If you do connect, Hong Kong and Taipei are the most practical hubs, offering frequent onward flights to Tokyo and efficient transfers, though they add significant travel time compared to flying direct."

      "q9": {
        "question": "How reliable are on‑time departures on this route from Seoul to Tokyo?",
        "answer": "On-time performance on this short regional route is generally good, but delays can occur due to air traffic congestion over Japan and seasonal weather. Korean Air and Asiana Airlines tend to perform reliably, and early morning departures from Incheon give you the best odds of departing on schedule before congestion builds at Tokyo Haneda or Narita."

      "q10": {
        "question": "Which months have the best weather for traveling to Tokyo?",
        "answer": "Late March to early April offers iconic cherry blossoms with mild temps, while October to early November brings cool, clear autumn weather and fewer crowds than the spring peak. Both windows avoid Tokyo's hot, humid summer and the rainy season in June and July."
