When I was looking for a marshland close to Toyohashi City, Yanami Marsh and Kamitaka Marsh came up in my search.
It looked like a nice marsh, so I went there, but unfortunately I couldn't enter!
A quick search revealed thatApparently it's not open to the public.
I had no choice but to take a photo as a souvenir of my visit and then give up.
▼The location of Yanami Wetlands.
It must be somewhere inside here.
It is only open to the public for a short period in October.

▼To begin with, it is prohibited to enter Kamikama Wetlands.
Apparently only those involved are allowed in, so it seems they can only enter for research or other such reasons.

Let's investigate further...
Yanami Wetland, Kamitaka Wetland, and Onshinji Wetland are registered under the Ramsar Convention as part of the Tokai Hills Spring-fed Wetlands Group.
The Ramsar Convention is an international treaty on the conservation of wetlands, and 52 wetlands are registered in Japan.
summary
Although the exploration was unsuccessful, it is good that there is a system in place to properly protect the marsh.
Overuse of mountains and marshes is seen as a problem, but at the same time, it is also important to expand the scope of conservation efforts in order to develop the human resources required to protect them.
You need to think about how to strike a balance.
