On 15 December 1960, just weeks after Yamaguchi's suicide, a nationwide coalition of Japanese right-wing groups held a “National Memorial Service for Our Martyred Brother Yamaguchi Otoya" in the same Hibya Public Hall in Tokyo where Yamaguchi had assassinated Asanuma.[2] Since then, right-wing groups have held an annual commemoration of Yamaguchi's death anniversary each year on 2 November.[2] In October 2010, right-wing groups staged a large-scale celebration of the 50th anniversary of Yamaguchi's assassination of Asanuma in Hibiya Park.[10]
