Out after 10 Years (17): Other Beverages in Japan

Vending machines are everywhere in Japan. Even in small towns you can see them on narrow streets. Is that because of the hot and humid weather that Japan has for a number of months or companies simply intend to make more money? These machines sell different types of water (mineral, carbonated, flavoured, etc.), juices and maybe alcoholic beverages, as I never paid much attention to the last.

A small vending machine and the first one I saw in my first hotel in Tokyo

Nevertheless what I was looking for was Sake but since I never went to any restaurant for lunch and dinner (I don't think anyone drinks Sake for breakfast!) never had the chance to have any. I only bought a can from a 7-Eleven store and drank it but it was so strong that I couldn't finish it in one sitting. I knew there're different types of Sake and the good quality shall be expensive but never tried to by a high quality from a teal liqueur store or supermarket as they sell alcoholic beverages just like the American ones do. 

(Photo, top: 300 Ml Sake cans in convenient stores are sold for ¥259.6 which is nearly CAN $2.45, It has nearly 14.5% alcohol. Is it not too much?)
