Yomiuriland (よみうりランド, Yomiurirando) is one of the larger and well known Japanese amusement parks near Tokyo, first opened in 1964. It is situated on hillsides, and features modern thrill rides such as roller coasters and water flumes. It is home to Yomiuri Giants Stadium, one of the training fields for the Yomiuri Giants baseball team, and was the primary training ground before Tokyo Dome was completed. It is operated and run by the Yomiuri Group, the parent of media conglomerate Yomiuri Shimbun. Recently a bathhouse was constructed to attract more senior citizens.
