sentences:  An important moment in the development of the Aimachi Band came in 1970, when the Tenrikyo Young Men's Association invited the Band to perform at an event in Tokyo at the Nippon Budokan, a famous arena that was built to host the judo competition at the 1964 Summer Olympics events but has also hosted numerous other events such as indoor marching events and rock concerts, including those by groups such as the Beatles, Pearl Jam, Ozzy Osbourne, the Doobie Brothers and Journey.For this performance, the Aimachi Band designed its first field show using Japanese popular music and traditional block formations.The success of this performance led to discussions with Mr. Harada to organize, in March 1972, a marching band association for the bands in the midsection of the country, which was part of the All Japan Marching Band Association (in 1979, the name was changed to the All Japan Marching Band and Baton Twirling Association).
