Plan for mild, mostly pleasant conditions across Japan in May, though you should pack layers and a light rain jacket as the month bridges spring and the rainy season. The live forecast above shows current conditions for Tokyo, but temperatures and rainfall vary significantly from Hokkaido in the north to Okinawa in the south.
What is the weather like in Japan during May?
May is one of Japan’s most comfortable months, with mild temperatures and lower humidity than June. The cherry blossom season has largely finished in most regions by early May, though northern Hokkaido may still see blooms. Expect daytime highs in Tokyo around 22–25°C, while Kyoto and Osaka are similar. Southern Okinawa is warmer, reaching 27–28°C, while northern Hokkaido stays cooler at 15–18°C. Rainfall increases towards the end of May as the rainy season (tsuyu) approaches from the south.
What should I pack for Japan in May?
Light layers are essential because mornings and evenings can be cool, while afternoons are warm. A waterproof jacket or umbrella is wise, especially from mid-May onward. Comfortable walking shoes are a must for exploring cities and gardens. For those heading to higher elevations or northern areas, a fleece or light jumper will help.
Is May a good time to see cherry blossoms in Japan?
Only in northern Hokkaido, where some varieties bloom into early May. For most of Japan, the main cherry blossom season finishes in April. If you miss the blossoms, May offers lush green landscapes and fewer crowds.
Does it rain a lot in Japan in May?
Rainfall increases through May, especially in southern and central regions. Tokyo averages about 130mm over 10–12 days, while Okinawa sees heavier rain as the rainy season begins. Northern Hokkaido remains drier.
What is the weather in Japan in May and June compared?
May is generally mild and pleasant, while June is the start of the rainy season across most of Japan, bringing higher humidity, more cloud cover, and frequent rain. Temperatures in June are a few degrees warmer but feel stickier.
