我が亀清旅館の大浴場を見たら、吃驚しました: 濁り湯になっていました。通常は透明なお湯が白骨温泉みたいにミルキーになっていました。
外の気温の急な変更で(寒くなってきたなと思いました!)、たまにお湯がこうやって曇ります。自然な現象です。
Our main onsen bath here at Kamesei Ryokan had a surprise for us today -- the onsen water had turned milky. Normally, Kamiyamada Onsen's hot sring water is clear, but today it was cloudy, like Shirahone Onsen and the other 'milky-white' onsens.
If the outside temperature changes drastically, our onsen bath sometimes becomes cloudy like this. It's a natural reaction to the atmospheric change. My body was certainly reacting to the drop in temperatures lately -- apparently the onsen does, too!
