On the day we visited Happo-One, we also traveled to the Sea of Japan/East Sea. The closest large city in the area we visited is called Joetsu, if you want to check a map.
It was a beautiful, clear, warm day, and as you can see in the picture, Diane and Paige enjoyed the warm water. It wasn't quite "Hawaii-warm",
but I was surprised at how nice the water was, considering it was October.
