This week brings a classic autumn transition: a mix of sunshine and clouds early on, with conditions turning cloudier and wetter toward the weekend. Northern Japan (like Sapporo) will feel noticeably cool, while Tokyo stays mild and comfortable. Southern areas like Naha will remain warm and humid.

From October 8–10, weather conditions may become more unstable due to a developing typhoon (Typhoon Halong). Depending on its path, there’s a risk of heavy rain, strong winds, and rough seas, especially in Okinawa, the Amami Islands, and coastal areas along the Pacific side of western to eastern Japan. If you’re traveling in these regions, be sure to monitor local forecasts and ferry/flight updates closely.

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. Be sure to stay updated on the latest weather and flight information. For real-time updates on railways and airports, visit LIVE JAPAN's transport information page.

October is one of the most beautiful months to visit Japan. The summer heat has faded, and the air feels crisp and comfortable - perfect for sightseeing.

Trees across the country begin to show hints of autumn color, especially in the northern regions and higher elevations.

Seasonal foods like sweet potatoes, chestnuts, and mushrooms fill markets and restaurant menus, while cities host lively events and harvest festivals. It’s a wonderful time to enjoy Japan’s natural beauty and local traditions before the chill of winter sets in.
