200,000 azaleas over 23 hectares bloom on the hillside of the Nasu highlands, 1,100 metres above sea level. The best viewing season is mid-to-late May. The slopes of Mt.Nasu provide a full view of this incredible landscape. The fields of pink are nothing short of spectacular. A wooden walkway (accessible by disabled visitors) winds its way through flowering bushes allowing a close-up look and over a one-hour course.
