What is the best season to visit Japan?

### Response:
The best season to visit Japan is well known as Spring, especially between March and April when you can enjoy cherry blossom viewing. Because it is so popular, you will expect a lot of crowds especially in famous cherry blossom spots. Hotels and flights are hard to be booked and perhaps the most expensive. 

Another popular season is Fall. The weather is pleasant and many foreigners come to visit especially for fall foliage in November. And the good thing is that despite its beauty, it is expected to be less crowded than Spring during cherry blossom season.
