WEATHERPASS JAPAN builds your day from the sky above you right now. It ranks 147 experiences and sights across 15 prefectures — Tokyo, Kyoto, Osaka, Hokkaido, Okinawa and more — by how quickly you can reach them. Rain puts fully indoor places first, a heatwave puts air-conditioned ones first, and clear skies bring the open-air icons to the top.
On a wet day only one question matters: do you stay dry getting there? teamLab Planets, Sumida Aquarium, sushi-making classes, covered shopping streets — places the weather cannot close. Every card shows the travel time, the number of transfers and the walk from the station, so you can pick the option with the least time under an umbrella. Above 35°C the same logic is applied to heat.
Prices link straight to Klook, KKday and Viator. Which one is cheapest changes by venue and by date, so compare them side by side before you book. Venues you can simply walk up to and pay at the door are marked as such. Transit passes appear only when your route actually needs one, next to an estimate of the fares without it.
Areas covered: Tokyo / Kanagawa / Chiba / Kyoto / Osaka / Nara / Aichi / Ishikawa / Hiroshima / Fukuoka / Okinawa / Hokkaido / Miyagi / Aomori / Yamagata
Plenty — Tokyo is one of the best rainy-day cities in the world. Fully indoor picks like teamLab Planets, Sumida Aquarium, the Sumida Hokusai Museum, sushi-making classes and covered shopping streets all run rain or shine. WEATHERPASS reads the live forecast, shows only what's still open and reachable today, and compares Klook, KKday and Viator so you book the lowest price.
It changes per venue and per day: each site runs its own promotions, and the cheapest one for teamLab is often not the cheapest for Tokyo Skytree. That's why every experience links straight to all three, so you can open them side by side and compare before you book, instead of taking the first price you see.
When it's 33–38°C, treat the heat like rain: go fully indoor and air-conditioned. Digital-art museums, aquariums, indoor food classes and spa complexes are the classic escapes. WEATHERPASS switches to heatwave mode automatically above 30°C and puts cool indoor experiences first, sorted by how fast you can get out of the sun.
