[Request] Please do not ride on the ice of Lake Suwa [Dangerous]

Hello everyone, I have a request.
Do not ride on the ice of Lake Suwa

Please watch this video

The fact that it had enough power to rise up ice,
There must also be cracks nearby ice...
And it seems that the strength is still being applied to this day ( ;∀;)

There are some areas where the ice is thinned due to hot springs and gases that emerge from the bottom of the lake.
The weak parts will break first and then chain together, so when ice breaks, it is not at the "hole" level.
I think at least 10m square ice will break and sink in one go.

Please make your trip safe and enjoyable until you return home.
Thank you for your cooperation. ('ω')ノ
