I always loved the water; the beach, the pool, the river, the creek. As long as it's clean, I can bask in it or I can swim on it, it'll do. It's one of the place in the planet I'll go to whether I am home or abroad.
This picture was taken on a cloudy day when I visited Japan in the summer of 2008. Several people were camping on the shore and spending their day there. 
Noticing that no matter how highly industrialized the country is, and how many establishments are positioned near or on their waters, they still can keep the area free from pollution. Just notice how many boats and yacths are there and zero litter.
