Yoshimoto ∞ Hall

Yoshimoto Mugendai Hall is a public indoor stage owned by the Japanese entertainment conglomerate Yoshimoto Kōgyō situated in Shibuya, Tokyo. The stage opened on March 25, 2006 and has since staged the Yoshimoto Mugendai event hosting daily owarai performances and live broadcasts on television and over the internet. Yoshimoto Mugendai, which commenced on November 11, 2005, was held at the now closed Ariake Studio prior to the opening of Yoshimoto Mugendai Hall.

Mugendai means "infinity" in Japanese and the symbol ∞, often replaces the word itself in casual Japanese writing.
