We thought there was a chance this was an actual Japanese hotel in Vegas. It is not. It is upscale. Check In was nice. They have a concierge who is alway available by text. The bathroom is extravagant. But having spent a good deal of time in Japan at traditional inns, this is not that . Also could not get a reservation at the Nobu Restaurant but got room service from them. Very very good but way too much.
I would stay again. If you want to stay in a Japanese hotel, go to Japan. More
