Your first day in Tokyo after a long flight is not the day for a packed itinerary, no matter how excited you are. The good news is that a gentle, well-planned first 24 hours sets up the rest of the trip beautifully. This guide walks through getting into the city, handling jet lag, choosing an easy first outing, and keeping meals simple, with details checked against published sources. Fares, hours, and schedules change, so confirm current information before you travel.
Narita Airport is about 70 kilometers from central Tokyo, and Haneda is about 20 kilometers, according to a Fun Japan guide to airport transport. From Narita, that guide lists the Keisei Skyliner, which reaches Nippori or Ueno in about 40 minutes with reserved seats, the JR Narita Express, which serves Tokyo Station, Shinjuku, Shibuya, and Ikebukuro, and airport limousine buses that stop at many major hotels. Budget options include the Keisei Main Line and express buses.
From Haneda, the same guide lists the Tokyo Monorail to Hamamatsucho Station, where you can transfer to the Yamanote Line, the Keikyu Line to Shinagawa Station in about 15 minutes, and limousine buses to Tokyo Station and Shinjuku. It also notes that most Narita options do not run between midnight and 5 a.m., and suggests an overnight stay near the airport if you arrive very late. That article dates from 2017, so check current fares and timetables before you go.
Suica and PASMO are prepaid contactless cards used for trains, buses, and taxis, and many konbini and vending machines accept them too, according to Go! Go! Nihon. For overseas visitors, Welcome Suica cards are sold at JR East Travel Service Centers at Narita Terminals 1 and 2 and 3 and at Haneda Terminal 3. The same page says iPhone users can add a Suica or PASMO card in the Wallet app, and that Android users can add one through Google Pay, though some Android phones bought overseas lack the needed chip. Setting this up before you fly, or right at the airport, means fewer ticket machines to puzzle over while you are tired.
Traveling east is usually the harder direction, and Weill Cornell Medicine estimates about one day of adjustment for each hour of time difference. Its guidance, which draws on CDC recommendations, includes getting morning sun before the trip, drinking plenty of water, avoiding alcohol on the plane, and sleeping on the flight when it is nighttime at your destination. After you arrive, it suggests following the local sleep schedule right away, staying in well-lit areas during the day, and taking a short nap of about 20 minutes if you need one. It also mentions melatonin as an option, and the CDC advises taking it as directed by your health care provider, so check with your own provider first.
The easiest way to apply all this is to keep your first day simple. Drop your bags, freshen up, get outside into daylight, and aim to go to bed at a normal local time.
Senso-ji in Asakusa is a gentle, atmospheric first stop. Japan Guide notes that the temple's founding is traced to 628 and that it was completed in 645, making it Tokyo's oldest temple. The Thunder Gate, Kaminarimon, is the outer gate, and a shopping street of more than 200 meters called Nakamise runs from there to the Hozomon, the second gate. It sells souvenirs and traditional snacks. Admission is free, the grounds are always open, and the main hall is open from 6:00 to 17:00, or from 6:30 between October and March. You can wander at your own pace, sample a snack, and head back when your energy fades.
If crowds sound like too much, Shinjuku Gyoen National Garden is a peaceful alternative. Japan Travel describes a Japanese garden, French and English gardens, a greenhouse, and plenty of open lawns for walking. The nearest stations are Shinjuku-gyoen Mae on the Marunouchi Line and Sendagaya on the JR Chuo-Sobu Line, each about a five minute walk away. The garden is closed on Mondays and has set opening hours that can vary by season, so check the official schedule before you head out.
Busy districts such as Shibuya and Harajuku, and anything that needs a reservation, are better once your energy returns. Giving yourself a calm first day usually pays off with a brighter, more enjoyable second and third day.
The Japan National Tourism Organization describes depachika as the food markets in the basements of Japan's top department stores. They stock ready-to-eat lunches, pre-made bento boxes, gourmet sweets, fresh ingredients, and more, and the page suggests shopping outside the lunch and dinner rushes and looking out for free samples. Because many are connected to train stations, they are convenient on rainy days. A bento from a depachika or a snack from a konbini is a lovely low-effort first meal. Konbini are open around the clock in major cities, so a late-night bite is easy to find.
Arrive, take a direct train or bus to your hotel, drop your bags, and freshen up. Step outside for daylight and an easy walk, either in Asakusa or in a garden. Pick up a bento for an early dinner, enjoy a quiet evening, and aim for a normal local bedtime. Tomorrow, with a bit of rest behind you, the city will feel wonderfully welcoming.
