Our tour guide, Sun Yuren, was incredibly kind and managed our schedule perfectly, giving us the most time. This trip was incredibly worthwhile and would have been impossible to complete on your own. The scenery at Kamikochi and Mt. Tatebe-Kuroyama was truly stunning. We were truly fortunate to have excellent accommodations and meals this time.
