Although most tourists flock to Tokyo between March and April each year, in time for cherry blossoms, the city can be visited all year round and in every season you can see it from a different point of view. In autumn, for example, the leaves that become orange/red make the landscape special. In terms of temperature, summer is really very hot while the winter can be very cold and that's why autumn and spring are the most requested seasons. December and January are two special months for Tokyo and Japan as they celebrate the transition to the new year in a very suggestive way. So I suggest you seriously think about leaving and visiting Tokyo at this time. For example: if you are in Tokyo on the second Monday in January, you can be part of the Coming of Age Day celebrations, for the newly-classed adults that have turned 20 in the last year or will do so before March 31. All the young women wear an elaborate kimono or furisode, a long-sleeved kimono for unmarried young women, on this day.
