Perhaps the best time to visit Tokyo is in the spring, from April to early May. At the start of this period (known as hanami) flurries of falling cherry blossom give the city a soft pink hue and by the end the temperatures are pleasant. October and November are also good months to come; this is when you’ll catch the fireburst of autumn leaves in Tokyo’s parks and gardens.
Avoid the steamy height of summer (late July to early Sept), when the city’s humidity sees its citizens scurrying from one air-conditioned haven to another. From January through to March temperatures can dip to freezing, but the crisp blue winter skies are rarely disturbed by rain or snow showers. Carrying an umbrella in any season is a good idea but particularly so during tsuyu, the rainy season in June and July, and in September, when typhoons occasionally strike the coast.
When planning your visit also check the city’s calendar of festivals and special events for any that may interest you. Note also that many attractions shut for several days around New Year when Tokyo becomes a ghost town, as many people return to their family homes elsewhere in the country.
