There is a replica of Denmark's Little Mermaid in the Yokohama Harbor on the outskirts of Tokyo. map

The statue very appropriately is placed on the corner of the building that houses the Scandia Restaurant. A small section of the corner of the building was carved out to make room for the half-size statue.
