I learned that Calfornia has glass beach from this class, Japan also has it. The location of it is Omura city, in Nagasaki prefecture. It created by various color and size of glass. I have been to there once. At that time I was impressed by it, because it was very beautiful. However, there are different point between California and Japan. It is that artificial or natural. I'd like to go natural glass beach in California somedays!!
