5Suijin Park
Enjoy "Somen-nagashi" while gazing at the cool waterfall
The "Somen-nagashi" experience at Suijin Park in Ofuku, Mine City, is a summer tradition that can be enjoyed by children and adults alike. The event attracts a large number of visitors every year, as they can taste somen noodles in cold natural water. In addition to somen noodles, there are also snacks such as frankfurters and yakitori, as well as juices and alcoholic beverages, so visitors can enjoy themselves without getting bored.
The open-air pavilion is a great place to enjoy nature to the fullest, with its clean air and cool sound of the waterfalls. On hot days, you can even see children enjoying playing in the water.
Suijin-no-taki waterfall is located right next to the pavilion.
The best spot in Suijin Park is "Suijin-no-taki" (Water God Falls), where more than ten waterfalls are formed in the shade of dark greenery along a 500-meter mountain path along the Suijin River. The waterfalls, with their cool sound, are beautiful in each of the four seasons as they pass over strange and mysterious stones. Therefore, while many visitors come in summer to enjoy the famous "Somen-nagashi" (flowing noodles) and the natural coolness provided by the waterfall, many people come in autumn for the autumn leaves.
The udder-shaped rock that appears along the way is called the "Milk God," and legend has it that if you drink a drop of water from it, your milk supply will increase. Please look for them when you visit.
