Udon Energy - AkihabaraNews.com

Kagawa prefecture, located on Shikoku (the smallest of the 4 main islands of Japan), is famous for having perhaps the best Udon noodles in Japan. It's the smallest prefecture in Japan, but they have more than 900 Udon restaurants across the prefecture (as compared to only 300 convenience stores in the prefecture).

A lot of udon gets eaten in Kagawa but a lot of excess udon gets generated as well and typically goes to waste.
