Meotoishi site is a settlement and monument site from the Middle Jomon Period (c. 3,500?2,500 BC). Over one hundred clay figurines (dogu) were found around a megalith built as a stone monument. The location of the megalith can be linked to the prehistoric astronomical landscape. From the megalith, you can see the sunset behind the obelisk on Mt. Jizogatake, one of the three peaks of Mt. Houo in the Southern Alps, on the spring and autumnal equinoxes.
