Japan changes a lot through the year. Timing your trip around the seasons is the cheapest upgrade there is.

1. 1.Use the official blossom forecast

   Cherry blossoms open at different times across the country. JNTO publishes a forecast each spring, which is far better than guessing from last year.

2. 2.Autumn leaves have a forecast too

   JNTO runs an autumn leaves forecast as well. In Tokyo, the colour usually peaks later than first-timers expect, so check before booking.

4. 4.Plan a Plan B for typhoons

   Most typhoons form between July and October. They mainly affect Okinawa and Kyushu, but Tokyo is not immune. Trains can be suspended, and storms usually pass within a day.
