Yogodo Hall houses the Yogoshu, which are a group of Buddhas that follow the teachings of Bodhisattva Kannon and support his enlightened activity. (yogo refers to the ability of the Buddhas to temporarily disappear and reappear in the world).
The present Yogodo Hall was constructed in 1994 to commemorate the 1,200th anniversary of the birth of Ennin, who was largely responsible for the flourishing of Senso-ji. It features a ferroconcrete structure and traditional roof tiles. On a platform at the center of the naijin (inner sanctum) sits a statue of Bodhisattva Knnon. To the Kannon's right and left are seated eight Buddhas, each of which protects one or two animals of the oriental zodiac cycle. In this cycle derived from traditional notation in China, each year is represented by one of 12 animals; therefore, each person is protected by the Buddha amongst these eight that corresponds to the year they were born.
