Ariyori

Ariyori was the son of Saeki Ariwaka, the governor of Etchū Province (modern-day Toyama Prefecture). At the age of sixteen, he ventured into the Tateyama mountains, pursuing a white hawk. During this expedition he shot a bear who transformed into the Buddha Amitabha (Amida). This experience led Ariyori to ordain as a monk, taking the religious name Jikō, and he dedicated himself to spiritual pursuits on the mountain.

Ariyori is said to have then established Tateyama as a sacred pilgrimage site embodying Buddhist concepts of hell (Jigoku) and paradise (Jōdo), represented by the mountain’s landscape. A notable legend involves his nurse, who accompanied him but couldn't complete the journey; in frustration, she cast aside her mirror, which transformed into the famous landmark known as the "Mirror Stone." His story was popularized through the Tateyama Mandalas—illustrated scrolls depicting scenes from his life and symbolizing spiritual enlightenment. Ariyori’s blending of Buddhist and Shinto beliefs reflects the religious syncretism characteristic of medieval Japan. Today, Ariyori’s legacy endures, drawing pilgrims and visitors to Tateyama, inspired by his symbolic narrative of transformation and spiritual commitment.
