The best time to visit Japan is between March and May or between September and November. During these periods, the weather is generally mild and dry, making it ideal for travel and outdoor activities. The spring months feature the famous cherry blossoms, providing breathtaking scenery, although it's a popular time with tourists. The fall season showcases vibrant red and gold foliage that enhances the natural beauty of the landscapes. If you prefer smaller crowds and cooler weather, October through March is a good period as well, especially for visiting places like Kyoto to avoid peak tourist seasons.
