A second half of the 1950s, Tokyo Metropolitan City Planning Council approved the underground parking garage construction at the part of Hibiya Park in the central area of Tokyo. In this council, many members discussed the right and wrong of the parking garage construction concerning the fundamental law, ownership, supervision, toll system and management by private enterprise. On march 1957, this planning and project were approved at the Council. The Japan Highway Corporation (public sector) began the construction this parking garage and spent one year and eight months. The total cost was about thousand and forty million yen. This garage began the operation on June 1960, and is now managing by private enterprise.
