I can find very little information about Fudo-inm temple 92 of the 108 temples on the Kyushu pilgrimage, other than the honzon is Fudo Myo-O and the temple was founded in the 13th Century.
There were several stone Fudos in the grounds, and all the structures were concrete and fairly modern.
What was most obvious were the hundreds and hundreds of large pet bottles each containing a candle. Obviously part of some new year ceremony or celebration.
