October in Japan marks the true arrival of autumn. The lingering heat of summer fades, and the landscape begins to transform as trees gradually change color, with the autumn foliage front moving from north to south. The air becomes crisp and clear—warm and pleasant during the day, yet a little cool at night, making it the perfect season for walks and sightseeing. Across the country, harvest festivals and local celebrations showcase regional traditions and flavors. Seasonal ingredients such as chestnuts, sweet potatoes, freshly harvested rice, and mushrooms enrich the dining table, offering a taste of Japan’s autumn abundance.
