Arrive at Narita or Haneda and take Narita Express or limousine/airport train (or taxi if late). Settle into a centrally located hotel (Shinjuku/Shibuya/Ginza) for ease of sightseeing.
Take Odakyu Romancecar or Shinkansen to Odawara then local transport into Hakone (1–2h depending on route); buy a Hakone Free Pass if exploring the area.
Take the sightseeing boat and Hakone Ropeway (ropeway hours commonly ~9:00–16:00) for volcano and lake views — Owakudani sometimes restricts access for volcanic activity, so check ahead.
Return to Hiroshima Station and begin the long rail journey northwest to Kanazawa (multiple transfers; expect ~4–5 hours). This is a long travel day — consider an evening arrival in Kanazawa.
Choose Odaiba for seaside skyline views or a pre-booked TeamLab Borderless/Plan exhibit (confirm open hours; exhibitions often require tickets), ideal for a modern art/tech experience.
Brunch near your hotel and finalize check-out. Confirm airport transfer time depending on Narita or Haneda departure (allow 2–3 hours transit/processing).
