We are travelling to Nagano on March 24 to 30. Can u recommend a place in Nagano where I can see igloo?
The main place to see igloos in Nagano is at Shinanodaira in Iiyama from late January to February. Unfortunately, they are gone by the beginning of March.
If you are interested in snow activities, you may want to see this page for snowshoeing, snowmobiling, and other related info.
For great winter scenery, I recommend visiting the snow monkeys at Jigokudani Yaen Koen, the 2,600-meter heights of Senjojiki Cirque, or one of Nagano’s many ski areas like Hakuba, Nozawa, or Shiga Kogen.
I hope that helps answer your question.
