Japan starts the week with plenty of sunshine, but conditions will become increasingly unsettled as Typhoon No. 6 (Jangmi) and a seasonal weather front move across the country. Rain, strong winds, and rough seas are expected from June 3 to 4, particularly across western and eastern Japan, while northern regions may also see periods of heavy rain and thunderstorms. After the typhoon passes, much of the country will remain under cloudy skies with occasional showers through the weekend.

As mentioned above, Typhoon Jangmi is bringing extreme winds, dangerous storm surges, and torrential rainfall to Okinawa and the Amami Islands. It is expected to pass south and east of Japan between June 3 and 4, bringing periods of heavy rain, strong winds, and rough seas to western and eastern Japan. Parts of northern Japan may also see heavy rain and thunderstorms as the system moves through.

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.
