Sennenji is a Jodo sect temple located in Kusano, a former post town on the Hita Kaido east of Kurume.
It is said the temple was founded in 1233 and the Amida statues is an Important Cultural property.
It has a nice gate, and the main hall is unusually painted in vermillion, but otherwise not particularly noteworthy.
However, several sources say that it was known as the Nikko of Kyushu, or the Toshogu of Kyushu. The Toshogu in Nikko is the famous shrine/mausoleum of Tokugawa Ieyasu, and is known for its colorful and intricate carvings.
Supposedly the interior of the main hall here is covered in murals and the ceiling has a fine dragon painting, but I have yet to see a photo from the interior and can find no reports of anyone ever having been inside...
A modern, secondary building did have a small carving on it.....
It is also said that the famous garden designer Kobori Enshu designed the garden, but again there was no way to access it to see.....
Literally across the road is a large shrine which though unpainted, does have a lot of carvings, so maybe that is what the reference is to....
