Temple 22 of the Shikoku 88 temple Pilgrimage is Byodo-ji, located near the coast in Anan City, Tokushima.
Its name means "temple of equality" and it belongs to the Shingon Sect. The main deity is the healing buddha, yakushi Nyorai.
According to legend it was founded by Kobo Daishi who also carved the statue of Yakushi. He also dug a well that produced milky white water which is believed to have healing qualities, especially for eye ailments.
I was hoping to pick up some of the water, which is of course available for a small price, but unfortunately the water was not usable as the recent typhoon had contaminated the well with run-off.
