BEWARE:||IF You pay your spa/onsen bill with a credit card they will AUTOMATICALLY calculate the bill in your home currency "for your ease" and THEIR benefit-- the exchange rate they give you is MUCH LOWER than my credit card company was providing me. TELL THEM "NO"-- provide bill in YEN (then you get the exchange rate from your credit company-- much better deal for you, not for them)||||As for the Onsen itself-- Fair to Average--PRICEY (I downgraded it to POOR due to the billing issue). (I guess they also have a Hotel attached to this property). ||This review is for the ONSEN SPA.||||I went to this "in town" Onsen (mineral bath spa house) after my "Cup Noodle" Museum visit — for this onsen, in the middle of a major city without natural access to a hot water spring— they truck in the water. ||||It was a good ONE-TIME experience— but as I’ve been to MANY spas in China, ALL that put this one to shame I wouldn't go back to this one…But go and be aware. I went solo and speak no Japanese...so was flying by the seat of my pants, except I wasn't wearing any pants in the spa.||||So in essence you go into same-sex only areas: 1) clean/wash/shampoo yourself VERY WELL sitting on short stools in a little 1/2 sectioned off cubicle in a row of 15 other such cubicles…then and only then, you have the option of dipping in the indoor pool 1.5 ft. deep, or the outside shallow pool/in a natural setting, or outside in a cedar tub in same natural setting overlooking the bay-- very nice of a sort….all on the 7th floor of this building. I didn't go to the top floor--where I hear you can view the huge ferris wheel and soak your feet in hot water (that area is co-ed so everyone is wearing their spa clothes)||||If too hot—options: sit 1/2 out of water, get out of hot water, or go to the COLD water plunge. In addition, there are dry sauna, steam sauna, steam herbal sauna, and full-body scrubbing room done by little Asian women. ||||Then the next option is to put on a spa-provided outfit and wander bare foot into a restaurant area…there is a one with menus (photos, no English) and a buffet with food sold by weight (nothing marked in English, no instructions that is the way it is sold—) all a crap shoot…my six item 28usd meal with one beer, had only two items I should have bought—I am learning! ||||Supposedly there is a room where you can lounge in huge lounge chair and watch your own individual TV— never found it. ||||By the end of two hours I was cooked “well done”. And knew the bus I needed (comes only once an hour) was soon arriving…so I checked out— two hours, several very nice relaxing soaks (2500yen for entry), two great dim sum shumai (didn’t like the other items), and a nice very cold glass of Kirin beer—the whole learning experience a pricey 55usd (65% of that was the food and drink).
