I Go to Yunishigawa Dam

I went to Yunishigawa dam and joined a sightseeing tour riding on an amphibious vehicle. 

You cannot call the vehicle car nor ship. It was able to run both on a road and on a lake.

The vehicle had a front window but no side windows for passengers. 

So, it was very cold. We were showered with lake water when going from road to to lake surface.
