The main central tower is 55 meters tall and features a museum as well as an observation platform from which tourists may enjoy spectacular panoramic views of Osaka. The warlord Toyotomi Hideyoshi, who dominated Japan at the period, erected Osaka Castle between 1583 and 1585. It was designed by Japanese architect Kikkawa Hiroie and has been described as "a little bit Chinese, a little bit Western." It was mainly built with stone extracted from around the city and its vicinity. Osaka Castle is located in Umeda, one of the most expensive areas of Tokyo City. The castle grounds are open to the public daily except for during special events or when it is closed for restoration work. There is a small fee to enter the castle grounds but this includes entry to all of the attractions within the complex.
