Many travellers who arrive in Japan aren’t quite prepared for the weather. The wind and the rain can take people by surprise, as can the sticky heat of a Tokyo summer and the frosty nights that hit the country’s north. One of the first steps towards a great adventure is deciding when to travel, so check out our easy guide below to get a sense of your ideal season in some key destinations.
