Just have to share this wonderful experience! It's a japanese spa that offers every spa service imaginable and large communal "tubs". They are like being in a public fountain, only private. You can practically swim in them. There is a restaurant there too. At present the restaurant has entered a James Beard Foundation challenge for a more sustainable burger. Wagyu beef topped with a chili stuffed with goat cheese. Amazing. They offer four different flights of sake. What a way to treat yourself.
