Mount Haku was designated as a quasi-national park in 1955. It became a national park in 1962 and was renamed Hakusan National Park. Because the central part of the mountain has much precipitous terrain, there are very few roads and, as a result, little human intrusion into the area. Also limiting human intrusion is the designation of the park as a Wildlife Protection Area, covering over 38,061 ha. The park stretches beyond the mountain's borders into Toyama Prefecture.
