Sake is a traditional Japanese alcoholic drink which is made from fermented rice. The raw material is different from the rice that we eat. The rice called Yamadanishiki is very famous as a raw material of sake. Sake breweries are located in many places such as cities and countrysides throughout Japan. Half of sake in Japan is produced in Kansai region which includes Shiga, Kyoto, Osaka, Hyogo, Nara and Wakayama. Especially Hyogo and Kyoto are very famous production centers. Since there are some Sake Museums in Kyoto and Hyogo, I recommend you to go there for sightseeing. You can experience sake-tasting and know how to produce sake in some museums. The entrance fee of most sake museums are free.
