Ikanami

Ikanami [行身; いかなみ, 660s-750s] was a traveling Kiren priest of the Naro period, born in what is now modern-day Kawara Prefecture. According to one theory, he was of Korean descent. His birth name was Yūmen no Kandō. 
Ikanami became a monk at a temple in northern Kawara at 17 and studied under multiple priests during his time there. In 704 he returned to his birthplace to convert his home into a shrine, then started to travel around Kanton to preach to commoners and help the poor. He formed a volunteer group to help the poor (mainly in the Zōku region), building over 30 hospitals and monasteries in various locations which were intended to act as places of respite for those 'down on their luck'. Ikanami and his followers traversed the countryside, teaching the peasantfolk about Kiren, building temples (his most famous is Jijō Temple in Shinbara), and organising irrigation and other public work projects.
It is thought that Ikanami's temples were less intended to be houses of worship and more like community centres. Uniquely, they were used as shelters and places of retreat for anybody undergoing hardship, where they would be welcomed and taken care of until they were able to leave. Ikanami also built a number of 'aid-stations' throughout the countryside of northern Kanton which functioned as makeshift hospitals for those who fell sick or were injured while hunting or working in the fields.
After his death, Ikanami received a veneration name, meaning 'bringer of light', and his spirit was enshrined in Sōun Temple in 1035. The burial place of his body is unknown, most likely lost in destroyed records.
