Tokyo's curated selection covers 72 activities across 6 interest lenses. Adventure, Family & Kids, and History & Heritage fill the daytime hours but depend on dry weather. Food & Drink, Nightlife & Evening, and Rainy-Day & Indoor hold up when it rains. That 3-and-3 split is the organizing fact for any late-summer visit. August averages 33°C highs with 13 rain days. September cools to 29°C but still delivers 14.
Build each day in Tokyo around a weather-proof lens and add an outdoor pick when conditions hold. The 12-activity Rainy-Day & Indoor shortlist works as a same-day swap when rain hits. Food & Drink and Nightlife & Evening tend to carry the evenings regardless and give a September trip its structure. With 14 rain days that month, the 3 weather-resistant lenses form the spine of any itinerary.
August's 33°C highs and 13 rain days favor the indoor and evening lenses over outdoor picks.
