| With the exception
of the Hokkaido area and the subtropical Okinawa region, the weather
is mainly temperate, with four seasons. Winters are cool and sunny
in the south, cold and sunny in the Tokyo area (which occasionally
has snow), and very cold around Hokkaido, which is covered in snow
for as long as 4 months a year. Summer, between June and September,
varies from warm to very hot, while spring and autumn are usually
mild throughout the country. Rain falls year round but June and
early July is the primary rainy season. however, Hokkaido is much
drier than the Tokyo area. Rainfall is usually intermittent with
sunshine. Typhoons are usually occur in September or October but
rarely last more than one day.
Lightweight cottons and linens are required all summer in most areas.
There is much less rainfall than occurs in Western Europe. Light-
to medium weights in spring and autumn; medium- to heavyweights
for winter months, depending on the region. Much heavier and warmer
clothes are required in the mountains all year round.
