For a while after the war ended, the public hall was seized by the stationed troops and allowed to be used as a public hall only during the daytime. When the seizure was eventually lifted and the hall’s function as a public hall was fully restored, Tokyo’s reconstruction from the war got underway, and the desire of the citizens of Tokyo for cultural activities increased. A succession of music and performing arts appreciation groups such as the Tomin Gekijo, TOKYO Ro-On, and the Music Culture Center, which organized a wide range of workers and ordinary Tokyo citizens, came into existence.

The number of requests for use of the public hall from these groups, as well as broadcasting stations, newspaper companies, music offices, and others, became so large that the decision on who to use the hall became overwhelming. So they held a lottery on the stage of the public hall, and at times as many as 500 people gathered. First they used twisted paper called kanzeyori, then amidakuji (ghost leg), and finally a lottery machine with marbles in a square wooden box. However, as the number of participants increased, they could no longer keep up, so they borrowed a lottery machine from the then Nihon Kangyo Ginko to draw lots for lotteries.
