Osaka Expo was held in 1970. Among the events, the lunar rock displayed at the American gallary was the most attractive at the time. Well, a Japanese company produced the roof of the American gallary in fact. That was manufactured by Taiyo Kogyo Corporation established in Osaka. By the way, they also produced a roof of Tokyo Dome, the roof of the building on Shanghai Expo and so on.
