Yesterday was the beginning of cold winter;(ka-n-no-i-ri).
It will be very cold until the beginning of spring in the calendar;(Se-tsu-bu-n).
Now there is a very strong cold air mass over Japan island, and it is snowing heavily, especially at the side of Japan sea.
There was a snowfall of four meters in the Niigata area.
And it is reported some house were crushed in the weight.
They say they never have had such a heavy snowfall till now.
The weather may be strange, because it's too hot in summer and too cold in winter.
