There are two Daiwa Roynet hotels by Nagoya Station. They are however on opposite sides of the station. Shinkansenguchi in the name refers to this particular hotel being on the Shinkansen side of Nagoya Station.
As you exit from the Shinkansen side, the hotel is to your right and about 5 minutes walk. It is easy to see. It is the tall white building betwen a khaki coloured building and the blue coloured "Imon" building.
Daiwa Roynet Hotel is written in Japanese Kana ダイワ ロイネﾂト ﾎﾃﾙ｡
Our twin room was 16 square metres which, though small, was well arranged. It was clean, tidy, and the beds were comfortable.
This hotel is good value.
