When to Visit
Experiences to seek out and peak periods to plan around
Experiences & Highlights
Sakura peaks as highs lift from 15°C to 20°C; hanami picnics fill Ueno Park and the Meguro River boardwalk glows with evening lanterns — arrive before 9am to beat the crush.
Tokyo's oldest firework festival on the last Saturday of July launches 20,000 shells over Asakusa; expect 30°C nights and 80% humidity — yukata rentals near Sensoji sell out by noon.
November is among the driest months (77mm avg) with comfortable 17°C highs; Rikugien and Koishikawa Korakuen gardens glow red, and Meiji Jingu Gaien's ginkgo avenue peaks late in the month.
December averages 48mm rainfall and crisp 12°C highs — ideal for Marunouchi's champagne-gold tunnel, Roppongi Hills' Keyakizaka view of Tokyo Tower, and Caretta Shiodome's light show.
Peak Periods & Travel Advisories
June averages 187mm rainfall with 78% humidity and July climbs to 80% — frequent afternoon showers. Plan covered picks like teamLab Planets, the Edo-Tokyo Museum, or Shinjuku's depachika food halls.
Domestic travel surges push shinkansen seats to capacity and central hotel rates up 50–100%; reserve trains 4+ weeks out via the JR ticketing app and avoid the 14 Aug peak return day.
September is the wettest month (208mm avg, 81% humidity) with 2–3 typhoons typically tracking near Kanto; build flex days into itineraries and watch JMA alerts — trains pause when winds exceed 25 m/s.
