This hotel was constructed in luxury during the Japanese bubble economy term. So you can imagine the interior of the hotel from its outside.
Now the room charge is not so cheap compared with an ordinary hotel, but you will be satisfied with their hospitality that is the mixture of Western and Modern Japanese style.
I strongly recommend to stay here for every odd place lovers. Here is the reservation web site. Of course, you can use English there.
