Why do we have such a bad hay fever in Japan?
Hay fever is one of the big social concerns in Japan. There may be a few reasons, but the basic one is that after World WarⅡ, the Japanese government planted lots of cedars and cypresses to get timbers for rebuilding the burnt houses, but later the inexpensive imported timbers took place. As a result, cedars and cypress have been left in the forest without being cut down, scattering numerous pollen in springtime.
