The cultural assets under the ground lie
around here as complex ruins which range
from the Paleolithic era (about 15000〜16000
years ago) and the last period of Jomon ware
(about 2500 years ago) to the Edo period.
Most of them were accidentally found out
when construction of subway, road and housing
was made. Main ruins are as follows.

| Kami historical sites |
These are complex historical sites which
range from the middle years of the
Yayoi
period to the Japanese medieval period.
Especially
the great tomb in the middle years
of the
Yayoi period is one of the largest
one in
Japan. This tomb is oblong-shaped encircled
with a channel, 26 meters in length,
15 meters
in width and 3 meters in height. As
many
as 23 wooden coffins were discovered.
A wooden
coffin of double structure was found
at the
center, which was used for the main
buried
and also another wooden coffin used
for a
child was found. It seems that the
great
tomb was for an influential family.

| Uriwari historical sites |
The Uriwari historical sites were found
when a municipal graveyard was under construction
in 1939. Earthen wares, stone tools and copper
arrowheads ranging from 300 B.C to 200 A.D
were found on the whole district of the riverbed
of the Yamatogawa river. Among these found,
Kasen which is Chinese coin made in about
10 years A.D told us how far Chinese culture
spread to our country and gave us an influential
clue to set the date of the Yayoi period.
Besides pottery ranging from the medieval
to the modern period was found.

| Uriwari kita historical sites |
These are the historical sites of a settlement
surrounded by a large ditch ranging from
the former years of the Yayoi period to the
Japanese medieval period consisted of a pit
dwelling, a high floored warehouse, a well.
Besides we found a square tomb surrounded
by a ditch, a tomb with a wooden coffin and
a broken mirror made in the years of the
Shin, Gokan era (8 A.D 〜220 A.D).

| Nagahara historical sites |
This historical sites were found while
the Tanimachi subway line was under construction,
so excavation was made by lifting the construction.
We found it complex sites ranging from the
Paleolithic era to the Muromachi period.
One of them reminds us of the state of a
settlement in the Yayoi period, which is
composed of the site of dwelling, ditch,
tomb or so. The settlement left traces of
suffering from a fire. There is a site of
an ancient burial mound, square at the front,
and rounded in the rear beyond 100 meters
in length, where comma-shaped beads, glass-beads
and clay images of horse and house were furnished.
And the settlement leaves traces of diversified
zones that tells us the transitions of period
from ancient times to modern times. A clay
image of a vessel which was preserved remarkably
good was found on April in 1988. It is the
precious cultural heritage for us to be able
to study the structure of the vessel at that
time.
