Breakfast was served in a dining hall for both of our days at the Nishimuraya Hotel Shogetsutei. There was a ton of variety in what was available and it was all quite good. I loved all the small bites you could choose from including Tajima beef croquettes, fresh okra, oden, and perfectly cooked onsen tamago.
The hotel itself is beautiful and grand. It's like something I would imagine from the 50's or 60's. Very mid-century modern which still holds up today. The highlight is an expansive window wall that overlooks a picturesque garden.
Of course this place is known for their hot spring baths. In addition to their large public baths (separated for men and women, with an inside and outside area for each), they have private spas which you can book for an additional fee. We were lucky and reserved while they had a special deal which gave us one free session in one of their private spas. We opted for the Gingetsu (Japanese Style) which had a rock sauna room. There was even a lounge area where we could just chill after getting out of the bath with a free bottle of bubbly. An amazing onsen experience!
