Sanjo-in, temple number 20 on the Kyushu pikgrimage was a few kilometers outside of Nakatsu not too far from a major shrine, Komo hachimangu.
There were two very small halls and this must have been the main building although it was locked and there was nobody around.
The large Kannon statue was a Bokefuji Kannon, a modern version of Kannon that is becoming increasingly popular as its forte is prevention of senility and dementia.
There were some jizos as well, but there was not a lot to see. For many people the temples are the most important points of a pilgrimage, but for me they are just points along a journey....
