清水建設
In August 2005, the company bought land in front of the east exit of Takasaki Station through Shimizu Corporation. This was scheduled to be completed in 2007, becoming the location of a large city store, and doubling as the company headquarters. There was initially a plan to build the store in the Minato Mirai 21 area of Yokohama, but the plan was changed, apparently because the Yokohama city government expressed concerns about traffic congestion in the area.
