The worst time to visit Tokyo
Unfortunately for some, summer is the worst time to visit Tokyo. The warm temperatures attract high numbers of tourists, and as schools are closed for holidays, it gets worse with crowds. Visiting the parks, museums, and other historic spots become limited, with the long queues from the large crowds attending. Prices for most services increase with the demand, and it results in flights, accommodation, and park fees getting hiked along with most hotels remaining fully booked.
The temperatures stay high and constant throughout the entire season, and on the hottest days, they become oppressive and may not make a good time for outdoor activities. The rainfall comes with more interruptions to tours in Tokyo, especially when accompanied by thunderstorms and strong winds.
