Jizohon Daihoyo at Zojoji Temple

Jizohon Daihoyo (地蔵尊大法要), or Sentai Kosodate Jizoson Daihoyo (千躰子育地蔵尊大法要), is the annual grand festival for the more-than-a-thousand stone statuettes of Jizo wearing a red cap located on the northern edge of the temple grounds. These statues are called Sentai Kosodate Jizoson (千躰子育地蔵尊) which literally means "a thousand child-nurturing Jizoson" - Jizo(son) is a very popular Buddhist deity in Japan.
At this event, a procession marches from the Daimon Gate near Daimon Station of the Toei Oedo Line & Toei Asakusa Line, toward and into the temple.
