For those with an appreciation for art and who may want to feel a little cooler in the summer heat, nearby Matsumoto on the western slopes of the surrounding hills is a place called Kiyomizu Highland named after the Temple there that was the original temple from which Kiyomizu temple in Kyoto was named. The locals there are putting on an art festival with a variety of open Studios and even musical events at the Kiyomizu Skyland resort hotel over the next two weeks.
Should you want to vistit or even pop in on the original Kiyomizu temple take a look at the schedule below or the facebook page ( https://www.facebook.com/KiyomizuArtfes?fref=pb&hc_location=profile_browser)if you can read or work with Japanese with a translator.
While you are there you can take a nice Onsen style bath with a great view of the entire Matsumoto Valley and along the Japan Alps at Kiyomizu Skyland. The temperature up their is a good 5 degrees cooler making it a popular mountain cabin locality. You may even spot some monkeys getting about along the way.
