The pictures on the site do not do it justice! This place is amazing with amazing staff. We wanted a beach trip, and the beach on the site didn't look that great so we opted for another beach before checking in. MISTAKE! The beach right next to the hotel is beautiful and when we went, barely any people there except surfers in the water. The water is turquoise and warm and it feels like you are in the tropics just outside of Tokyo.
The staff were fantastic. We had dinner served in our room which was great and intimate. The food was amazing (very traditional Japanese food served in what seemed like endless courses). When we were done with dinner, a man came to roll out the futons which were more comfortable than my bed back home.
The baths are also amazing, but one side (the one with the traditional outdoor bath) is better than the other. They switch the sides for the sexes depending on the day, so make sure you're there when you can take advantage of it (especially at night). The views of the beach from the baths are amazing as well.
The location is the one downside. Getting to Shomida in general is a trek, and the hotel shuttles only run starting at 3, which if you want to get in early to take advantage of the beach means a taxi ride. They'll let you change at the hotel if you get there before check out though so you can take advantage of the beach.
Looking forward to going again soon!
