Japan’s rainy season (tsuyu) is officially underway across most of the country. You should prepare for a mixed bag of clouds, intermittent sunshine, and sudden showers, especially heading into the weekend. Fortunately, it will not be a constant downpour, and there are currently no major weather advisories to worry about.

Temperatures and conditions will vary widely depending on where your itinerary takes you. Hokkaido will remain pleasantly mild and comfortable. In Tokyo and Osaka, prepare for warm, highly humid conditions with rain early in the week and an increased chance of showers by the weekend. Down south, Okinawa is already experiencing true summer heat.

No typhoons are currently expected to affect Japan.

Japan's typhoon season runs from May through October, with most activity from July to September. During a typhoon, transit delays and cancellations can be expected.

June brings the start of early summer and Japan’s rainy season, known as tsuyu. Frequent showers blanket the country in fresh greenery, while hydrangeas and irises burst into vibrant shades of blue, purple, and pink. Temple gardens in Kamakura, Kyoto, and Tokyo are especially beautiful at this time of year.

Prefer to stay dry? June is also ideal for exploring museums, shopping arcades, and cozy cafes. Meanwhile, Hokkaido enjoys sunny skies and pleasant weather, making it perfect for outdoor adventures.

Seasonal treats include sweet melons, matcha desserts, and grilled ayu (sweetfish). Toward the end of the month, fireflies begin lighting up riversides and gardens, adding a touch of magic to Japan’s early summer evenings.

Tokyo begins the week damp before sunshine briefly brings a taste of early summer warmth. Clouds will gradually return, with light showers becoming more common toward the weekend. Expect daytime highs to climb from 21°C (70°F) up to nearly 29°C (84°F) before cooling slightly. Evenings will stay pleasantly mild, hovering between 17°C (63°F) and 21°C (70°F).

Bring lightweight, breathable short-sleeve tops and comfortable pants to gracefully handle the shift from warm afternoons to cooler evenings. A compact umbrella and water-resistant shoes will also be invaluable for navigating the city comfortably during intermittent showers.

Enjoy a mostly cloudy week with enough sunny breaks to comfortably explore outdoors. Expect daytime highs around 25°C (77°F) and refreshing nighttime lows of 16°C to 17°C (61°F to 63°F). The first half of the week looks dry, with rain chances increasing toward the weekend.

Clouds will dominate the week, though you will see a few brighter periods early on. Temperatures start comfortably warm in the mid to upper 20s before easing into the low 20s, with overnight lows holding steady between 15°C (59°F) and 17°C (63°F). Keep an eye out for rain as the weekend approaches.

The week begins with a mix of sunshine and clouds before settling into a more humid, overcast pattern with occasional showers. Summer has officially arrived, with daytime highs between 26°C (79°F) and 29°C (84°F) and nights gradually warming up to 23°C (73°F).

Expect classic rainy season weather with mostly cloudy skies and frequent light rain. It will feel warm and humid throughout your stay, with highs ranging from 27°C (81°F) to 30°C (86°F) and overnight lows staying around 22°C (72°F) to 23°C (73°F).
