Gunpei Yokoi
In August 2010, an exhibit titled "The Man Called 'The God of Games"' was shown in Harajuku in honor of Gunpei Yokoi (producer of "Sound Fantasy"). As part of this exhibit, Toshio Iwai hosted his own presentation called "The Genes of Gunpei Yokoi Inside of Me" where he displayed his works that had been inspired by Gunpei Yokoi: the Tenori-on musical instrument and the "Sound Fantasy" music game. Iwai brought the game cartridge and played it.
