Top North: Wakkanai

Wakkanai in Hokkaido is situated in over 45 degrees north. So, it is pretty cold in winter but cool in summer.
It faces two seas, the Sea of Japan (east sea for Koreans) and the Sea of Okhotsk. Thus, the north wind is very strong all year around.

Though the weather is quite harsh, there are many things which make you happy and warm.

Foods there are very tasty, especially fresh sea foods.
Also there is an amusement spot where you can experience dog/horse sledge, snow rafting, snow slider, snow shoe hiking and snow mobile ride.

Why don't you start your travel in Japan from this Top North?
