Spring: Mar, Apr & May 春
Haru is one of the best times to be in Japan. It’s spring and the country is warming up and livening up after a long, cold winter; cherry blossoms are blooming, snow is receding in the mountains and there’s a positive atmosphere on the streets.
Things warm up from the south. March may see spring erratically show both its warm and cold sides, while early April will see Japanese celebrating under cherry trees throughout Japan.
Remember, latitudes count - temperatures will be determined by where you are in the country - while swimmers may be at the beach in Okinawa in May, late snow may be falling in Hokkaidō.
Try to avoid peak travel times such as Golden Week; bring some extra layers of clothing in case temperatures drop; and if you suffer from allergies, remember that pollen and blooming flowers can bring on cases of hay fever in Japan too. Come prepared.
