Tokyo Weather in May
Planning a trip to Tokyo, Japan in May? Here's what the weather will actually be like — and why a lot of meteorologists call it one of the best months of the year to visit.
May in Tokyo is the sweet spot — comfortable temperatures, low humidity, and the calm before tsuyu (the rainy season that begins in June). Highs climb from the low 70s°F at the start of the month to the mid-70s by the end. Nights stay cool and crisp, dropping into the 50s and low 60s. Rain picks up to 10–12 light days for the month, but these are gentle spring showers driven by passing lows off the Eurasian continent — not the heavy tsuyu rains that come later.
There are no typhoons, no extreme heat, no freezing temperatures, and no major weather alerts. The trade-off: May is one of the busiest travel months in Tokyo because everyone knows it. Meteorologist Ian Schwartz breaks down what to expect.

Is May a good time to visit Tokyo?
Yes — often considered one of the best months of the year. Temperatures are comfortable, humidity is still low, you're past the cold of winter and ahead of the tsuyu rainy season that arrives in June. The trade-off is crowds: May is one of Tokyo's busiest travel months because the weather is so good. Golden Week (the first week of May) is especially crowded — it's a major Japanese holiday with multiple national days strung together.
What is the tsuyu rainy season?
Tsuyu (梅雨), literally "plum rain," is Japan's rainy season — a roughly six-week stretch from early June through mid-July when a stalled weather front parks over Japan and brings frequent rain, high humidity, and overcast days. It's not constant downpour, but expect rain at some point most days. In Tokyo, tsuyu typically starts around June 7–10 and ends in mid-July. May is the sweet spot just before it begins.
