The temple district, Teramachi, in Hagi is not on the main tourist route in the town but is well worth a visit if you are in Hagi for more than one day. There are a few historical buildings, a maze of narrow lanes, and of course temples... a few of which I have already posted about.
Kaichoji is a fairly large temple with an impressive gate, but what is interesting is the main hall which was originally built as a Confucian shrine. It was located at the Meirinkan, the domain school that revered Confucius. After the temple burned down in 1874 they purchased the hall and rebuilt it here as the temples main hall.
Red-bibbed Jizo abound, as do cemeteries. In my area graves are built behind houses, but in many places in Japan they are located at temples.
One can often see huge pyramids composed of gravestones, usually belonging to people who no longer have an living relatives in the area to care for them. These quite large, smooth rocks are unmarked and are I believe marker stones to unknown people.
