Following Hankyu Hanshin Hotels Co.'s recent admission that dozens of its restaurants misrepresented the food on their menus, "revelations" have emerged that several other establishments around the nation are doing the same thing.

The Ritz-Carlton hotel in Osaka and the Renaissance Sapporo Hotel in Hokkaido, for example, recently admitted using ingredients that are cheaper or more easily obtained than the premium items advertised on their menus.

On Thursday, even the prestigious Imperial Hotel Ltd. admitted that it once served frozen juice labeled as "fresh" at restaurants in its Tokyo and Osaka hotels.
