From fiery maple leaves to crisp mountain air and seasonal treats like roasted sweet potatoes and chestnut desserts, autumn in Japan is a multisensory celebration of nature, culture, and food. Running from mid-September to early December, depending on the region, Japan’s fall season is one of the best times to visit. The weather is cool and dry, the crowds are thinner than spring, and the country is blanketed in warm hues of red, gold, and orange.
