I referred you previous to the excellent on-line magazine for Japanese travel that goes by the name of MACHA. This article that is also on their site bears some promotion here. It is quite excellent and I really enjoy it in that it will take you out of the “usual” experiences of the region and introduces a few “really off the beaten path” locations that would be great for you to consider as well.

I like the piece within the article of a potential “udon adventure” and addresses and information on each udon shop there. If you are an udon fan this is a not miss “udon safari”. I highly recommend it.

Thanks MACHA for the great articles you have on Kagawa. These are great!!
