One of the biggest freshwater lakes in Japan, Fukushima prefecture's Inawashiroko Lake is certainly a sight to behold. Around the waters, you'll be able to find a number of marine based activities from sports to boat tours. Just as popular during the colder months, the "Shibuki Gori" ice sculptures that form from sprayed lake water freezing immediately when touching the lakeside trees. Beautiful and mysterious, this location is sure to excite the imagination.
