In what appears to be an unusual mix, tech giant Sony Corp. opened a "park" in the middle of the Tokyo's ritzy Ginza district on Thursday with four subterranean levels.

Ginza Sony Park was built at the site where the Sony Building, a former landmark, once stood. The ground floor consists of greenery and looks like a standard park, but the four underground floors consist of shops and free space.

Some of the shops sell food and goods, but much of the facility's 3,807 sq. meters of floor space is designed to let people hang out freely.
