Shitanoya Site is a circular settlement from the Middle Jomon period, about 5,000 to 4,000 years ago. It spreads from a terrace above the Shakujii River down to the low ground, and its dwellings and post-built structures form a ring about 150 m across. The period of use, known from pottery, is put at 1,000 years, and in March 2015 part of the west settlement was designated a National Historic Site.

02 ／ Hiegura

A headman's storehouse,built at his own cost, had 12 rooms.

In 1838 Shimoda Hanbe, the headman of Tanashi Village, asked the local intendant for a way to store barnyard millet (hie) and built a 500-koku storehouse in his own garden at his own cost. It was divided into 12 rooms in keeping with the zodiac, and the millet in one room was replaced each year. It was rebuilt once in 1863 and went out of use in 1873, and one part of the divided building is today's hiegura.

03 ／ Koshin monument

At the fork of Ome Kaido,a group of 23 raised a monument.

In 1723 a koshin group of 23 local residents set up this koshin monument at the fork where Ome Kaido meets Hanno (Tokorozawa) Kaido. It also served as a signpost, and with its base it stands over 3 m tall. It was moved around 1965 when the road was widened, and in 2006 to a spot relatively close to where it was first built.
