Introduction of Shibetsu marshland
Shibetsu marshland in Shibetsu town in eastern Hokkaido.
It is also the Po River Historic Site Natural Park, which is of great interest.
The area around the Po River, which slowly and winds meandering slowly, is designated as a national natural monument (natural protected area) in Shibetsu Marsh.
There are many wetlands in Hokkaido, so the Shibetsu wetland is slightly different from ordinary wetlands.
The total area is about 630 ha, which is very large, close to Ozegahara (760 ha), the largest mountain wetland in Japan. is.
For this reason, alpine plants of 2000m class in Honshu, such as those found in Oze, grow in the Shibetsu marsh at an altitude of 3m, and some plants, which are said to be surviving tundra plants during the ice age, are collected every May to early July. “Flowers" bloom.
Especially in Hokkaido, endangered species such as Ezogozentachibana, which can only be seen on the top of mountains, are growing along the wooden path of Shibetsu Marsh.
In addition, the environment is close to the subarctic, such as sphagnum moss colonies.
Furthermore, the Shibetsu marshland area is called Shibetsu Sekigun, and the number of archeological sites recognized is the largest in Japan.
Shibetsu marshland Sightseeing
In the period of archeological sites, from the Jomon period, the continued Jomon culture and rubbing culture that flourished in Hokkaido, the Okhotsk culture that is said to be a culture of the northern people, and the remains of Ainu culture that began in the Kamakura period in Honshu are also recognized.
Only around this Po River, we can tell the history of humankind in Hokkaido for 5000 years.
The word “Po" in the Po River, in Ainu, seems to mean a river flowing under the earth (pok).
A typical example is the Ichajin Carikarius archeological site, a nationally designated historic site.
It is located on a plateau at an altitude of 20m between the Po River and Ita-Incheon River. There are 1200 pit dwellings just after being confirmed, revealing the structure of the pit dwellings of the rubbing culture.
At the archeological site, there are 219 pit dwellings, mainly from the Rubum period, and a U-shaped cliff-type chasi (fort).
This is also a nationally designated historic site. On the plateau at an altitude of about 12m, 52 hollows of a circular or oval pit dwelling from the Jomon period to the continued Jomon period and 160 square hollows of the Rubum period were found. Is.
The Sanbongi archaeological site is on the left bank of the Shibetsu River, but there are 21 pentagonal or hexagonal pit dwellings of Okhotsk culture on the coastal sand dunes.
The remains of the continued Jomon culture have been excavated from the lower level, and it is also a nationally designated historic site.
In addition, at the site of the meandering river on the left bank of the Shibetsu River, more than 21 pit dwellings have been confirmed.
The greatest feature of these Shibetsu archeological sites is that they were not excavated and excavated, but most of them remained on the current ground surface as pit dwellings for thousands of years. And it is also a World Heritage candidate.
The Po River Historic Site Natural Park is an invaluable place where you can not only experience the rich bogs of nature, but also the longevity of mankind.
The Po River Historic Park is a paid visit.
The park is closed due to snow in winter, so the park is open from April 29 to November 23, with no regular holidays.
The park is open from 9:00 am to 16:30 pm and closes at 17:00.
However, it is a vast place, so if you take a walk slowly, it will take several hours, so you will only see a little in the evening.
Admission is 310 yen for adults, 100 yen for high school and university students, and free for junior high school students.
Transportation to Shibetsu marshland
In addition, since the area is very large, about 3 km on one way, it is convenient to use a free bicycle rental (bicycle rental) at the History and Folklore Museum.
Bicycles can be run on the moist wooden path.
It would be nice to have bear measures.
There is also a rental of bells for bears.
So is the time required for sightseeing one to three hours?
Free parking is available for 50 cars.
A little, the location is difficult to understand, so I hope you can refer to Google map .
Below is a bonus, “Kunashiri Island" taken from the coast of Shibetsu-cho.
It’s truly incredible to say that the island is so clear that it’s Russian territory and that you’ll be shot if you’re sailing past the middle of the sea.
After all, I realized again that Doto was a good place.
