Water Shield Grows in Freshwater Swamp -Junsai Swamp in Nanae-

July 23rd, 2017

Junsai Swamp (蓴菜沼) is a freshwater swamp in Nanae located in the northern part of Hakodate, and Junsai (蓴菜) means a water shield in English, so as the name suggests, the water shield is produced. The perimeter of the marsh is about 7.3 km. It is located in the western part of Japan National Route 5, there are walking paths and spring water called Gozensui (御膳水) as sightseeing spots in Junsai Swamp Area. But tourists do not seem to drink water that gushes out at Gozensui for being unfit to drink. In addition, the wooden paths seemed to destroy and not to enter. Fishing smelts can be enjoyed in a winter. There are a parking lot, a restroom and a buckwheat noodle restaurant. The buckwheat noodles are popular, too. Admission free. A parking lot is free of charge.
