The night view of plants in Muroran is becoming more and more popular these days. It is known as one of the Seven Greatest Plant Night Views in Japan. The Hakucho Bridge, lit up at night, and the observatory located on the top of Mt. Sokuryo (with an elevation of approx. 200m) were designated as "Night View Inheritances of Japan" in 2008. Muroran City has many observatories, where you can enjoy different night views.
