One of my fellow Americans living here in Chikuma City has a very professional personal home page. Not only does it include cute pictures of his family, but it has a very thorough 'Nagano Guide' page. It highlights day trip destinations as well as local areas of interest, with very detailed descriptions and photos. (Not to be missed are the great graphics on the Mori Shogun Keyhole Tomb entry!) If you are looking for information on sights to see around Kamesei Ryokan, this is a fantastic place to start.
