Here, there is an “eternal flame” that has been burning for more than 1,200 years since it was lit by Kobo Daishi (saint) (774-835) in 806.
This fire was also the original flame of the “Peace Light” in Hiroshima Peace Memorial Park.
Water boiled in a big teakettle over the “eternal flame” is said to be “miracle water that remedies all diseases.”
Drinking it is free! It would be a loss not to drink it.
