This time I went to Hirugami Onsen in Achi Village in Nagano Prefecture.
After walking around Tenryukyo Ohashi Bridge, we stayed at Hiruimachi Onsen at Yurui no Yado, Esan.
It was raining lightly at night, so I wasn't able to take pictures of the stars in Japan's best starry sky, but the next day it was clear and I went to Hirugami Onsenkyo and Tsukigami Onsenkyo to see the peach blossoms.
