Japan through the seasons: Average temperatures of different climates

The four different seasons in the country are distinct and each has a special twist to offer. Since the whole country is made up of large islands found in various locations, the seasons experienced in every region may vary with each other.

Spring is said to be the best season of the year to spend the holidays Japan. This is because of the fact that it is during Spring time that the world-famous Cherry blossom viewing occurs. Usually happening between March and May, it is the time of the year when temperatures are starting to mildly warm up. The air is rich and fresh with the scent of newly blossoming plants and flowers. It is also the time of the year when most regions in Japan are expecting the surge of tourists from all over the world.

Autumn might be one of the most romantic seasons in the country. Normally occurring between September to November, the autumn season in Japan is the season where leaves fall off from trees.  It is the time when everything turns into delicious hues of orange, red and brown. A very homey season of the year, this is the time when temperatures start cooling down again from the humid temperatures of the summer season.

The viewing of falling foliage is a popular activity in Japan for both locals and tourists and has been so for the past centuries. This is true since the fall of leaves all over Japan does not start and end at the same time of the year. Known as the "Koyo Front" the earliest time foliage falls in the year happens in Hokkaido in late August to early September. This front will now slowly move southwards until it reaches southernmost Japan in the end of November, there are maps available online to know the trend of this front.

It is also during this time of the year the rain falls heavily in various regions, a good indication that winter is finally near.
