He is Giant Torayan and is set at Nakanoshima museum in Osaka, which is newly opened in 2022. Its creator is Kenji Yanobe, a contemporary artist who has created machine arts based on ”memories and interest of childhood”. The place where Torayan is set is beside the 4th-floor stairs of the museum. He was created in 2005. His height is about 7M high and is made of aluminum, iron, FRP, brass, and styrofoam. He is to be a fantastic and ultimate weapon who only obeys the child can command of a child who only obeys the order of the child. For example, the child commands him to sing and dance and even burst into flames. There is a control room inside the Giant Torayan where a child can sit and control the robot., sing and dance, and burst into flames. A cutting-edge system is installed for him, which can distinguish between adult and child voices. Also, another system is the command device equipment, which runs the main unit.
