The 12 Most Beautiful Eco-Friendly Hotels In The World

Hoshinoya Karuizawa is located in the Nagano Prefecture just a short drive from the city of Tokyo.  The ceiling-high windows, continuous lines, and neutral colors of this resort hotel not only make it attractive but allow it to blend into its natural surroundings as well.  The resort is mainly powered by hydroelectricity via a system known as Energy in My Yard (EIMY).  One of the highlights here is the hot spring baths that date back to 1914.
