The interior of Phoenix Hall displays Japan's oldest existing “Kuhon Raiko-zu” in the Yamato-e style (Japanese painting style developed in the Heian period). In Buddhism, it is believed that the Amida Buddha (Amida Nyorai) classifies a person's deeds into nine levels at their death depending on the acts of merit and belief made while alive. This scene is depicted in the paintings on the doors and walls inside the Phoenix Hall. One of them is the “Nissokan-zu” which represents the scene of a superb sunset. The paintings are important historical materials that reflect the view of nature and religion people had in those days while also showing the culture of that time.
