- Inside the main hall are splendid status of the bodhisattva Kannon, most of them of the thirteenth century.
- One, the curious "horse-headed" Kannon, stands five metres tall.
- The head does not much resemble a horse's, but its glaring eyes and demonic features contrast markedly with the serenely composed faces of the other statues of the same deity.
- There is only one other building at the Kanzeon-ji, the Amida Hall.
- It contains statues of Amida Buddha and of the Four Guardian Kings, each carved from a single log of camphor wood.
- The oldest of the statues, carved in the tenth century, depicts the powerfuly built Guardian King Bishamonten.
- His feet and his curving belt extends down to the grotesque head of a lovable little monster.
- These Guardian Kings always stand on such creatures, meant to symbolize the forces of ignorance and evil which they have subdued.
