 The third main building is a 17-story hotel tower with 772 guest rooms, constructed on the site of Wright's building and opened on March 10, 1970.Although there had been talk of replacing the Wright hotel since before the planned 1940 Olympics, the first serious mention of plans for a new building was in 1963 when board minutes show that Takahashi Teitaro had been sent to the United States to look at hotels and start planning.At the October 16, 1966 board meeting, a plan to build a new hotel, to be completed in time for Expo '70 in Osaka, was unanimously approved.
