Tokosan Dainichi-ji is an urban temple in the old castle town of Saiki on the coast of southern Oita in Kyushu. I visited it on my 16th day of walking along the Kyushu 108 temple pilgrimage which is composed of only Shingon temples.
It was founded in the very early 17th Century and was connected to the ruling family of the castle. It was never a big domain. The honzon is , not surpringly, Dainichi, the Great Sun Buddha.
I believe this is a statue of Binzaru, though it is in much better condition than many Binzaru statues which are normally rubbed by petitioners for healing purposes.
I believe this chubby figure is a Kannon, though back in those days I was not paying as much attention to the names of many of the statues I encountered,,,,,
This is probably a shrine to Dakiniten, the deity that played a large part in the formation of the popular kami Inari.
