Arrive at Narita or Haneda; use the airport limousine, Narita Express, or Keikyu to reach central Tokyo and drop bags at your hotel so you can travel light. This sets you up to start exploring immediately.
Stroll the Outer Market for fresh sushi, tamagoyaki and grilled seafood; stalls typically open early but many food stalls operate until early afternoon (best visit before 2pm).
Walk Nakamise-dori to Sensō-ji, Tokyo's oldest temple; the temple precinct is accessible all day and the shopping street is great for souvenirs and snacks.
Choose a relaxed afternoon: Ueno Park (museums and ponds) or the lively Ameyoko street market for bargains and street food; many shops open 10:00–19:00.
Explore Akihabara's multi-storey electronics shops, game centres and anime stores; most shops open from 10:00 but maid cafés often take reservations earlier.
Stay at a ryokan with onsen for a traditional multi-course kaiseki dinner and restorative hot-spring bath; ryokan dinners usually served in the evening.
Visit the Peace Memorial Museum and Park to learn the history and see the Atomic Bomb Dome; museum hours typically 8:30–17:00 (closed Mon — check in advance).
Use airport limousine bus, Narita Express, or Haneda express depending on your departure airport and flight time; leave extra time for security and check-in.
