Natsu-iro no Sunadokei

Hourglass of Summer (Natsuiro no Sunadokei) is a Japanese visual novel that was released by Princess Soft. It was brought to the U.S. by the Hirameki International Group. It was one of the few interactive dating games that were first translated into English (although there was never an English voice dub for the US release). Originally, it was released exclusively in Japan in a PlayStation 2 format that could only be played on Japanese systems. Later, a PC version, also exclusively Japanese, was released, only this time with erotic content added to it. The U.S. version was released as an interactive DVD that didn’t contain sexual content.
