It
can
be
said
that
Nejo
is
the
birthplace
of
Hachinohe.
In
1333,
Nanbu
Moroyuki,
who
went
down
to
Oshu
according
to
the
Mutsu
Mamoru
Kitabatake
Akiie,
chose
Nejo
as
his
base
after
receiving
an
order
from
the
Akiie
to
wipe
out
the
Hojo
remnants
of
Kitabatake.
Although
it
is
a
lowland
castle,
it
has
a
highly
defensive
structure
that
takes
advantage
of
the
topographical
and
geological
characteristics
of
the
river
terraces.
Unfortunately,
the
south
1/3
is
divided
by
the
national
highway,
and
the
whole
picture
is
difficult
to
understand
due
to
the
progress
of
urbanization,
and
it
is
a
pity
that
it
can
be
understood
that
this
was
once
a
part
of
Nejo
with
a
few
remaining
earthworks.
The
Mabechi
River
in
the
north
was
protected
in
the
north,
and
the
west
swamp,
which
was
once
thought
to
have
had
a
considerable
amount
of
water,
was
used
as
the
guard
in
the
west.
The
defense
power
of
Honmaru
would
have
been
considerable.
The
place
where
the
main
enclosure
was
located
is
an
independent
hill,
with
moats
in
the
south
and
east,
the
Mabechi
River
in
the
north,
and
the
Nishizawa
in
the
west,
with
a
considerable
elevation
difference.
The
main
enclosure
and
main
shrine
have
been
restored.
I
can
only
imagine
the
Tsunegoden,
which
was
usually
used
for
office
work,
and
the
Okugoden,
which
was
the
residence
of
the
family,
because
only
the
bunch
of
pillars
are
arranged.
The
shack
seems
to
have
been
distinguished
from
the
restored
guest
one
and
the
stable,
which
was
the
place
of
life
for
the
horses,
where
only
the
pillars
were
placed.
The
workshops
and
smithy
workshops
were
dug
into
the
ground,
and
the
smithy
aside,
the
workshops
would
have
been
without
heating,
so
are
you
expecting
the
effect
of
alleviating
the
cold
in
winter?
The
thatched
roof
has
perfect
heat
insulation,
so
if
the
wall
area
could
be
reduced
to
some
extent,
it
would
have
been
possible
to
work
with
the
heat
of
a
brazier.
The
field
smithy
seems
to
have
been
exposed.
The
barn
is
made
of
pit-house
pillars
that
make
you
think,
"Why
is
there
a
Jomon
residence
here?"
Itakura
is
not
a
school
storehouse,
but
it
seems
that
it
was
a
well-built
valuables
storage
using
planks.
Although
the
well
is
buried,
a
cross
section
of
the
excavation
is
shown.
There
is
a
lightning
strike
on
the
old
ginkgo
tree
on
the
northern
slope.
Probably
it
was
a
replacement
for
a
lightning
rod.
As
you
can
see
from
the
Jomon
archaeological
site
and
the
castles
in
each
area,
people
in
the
old
days
used
the
land
well
by
choosing
the
base
of
their
lives
with
the
utmost
care.
If
you
haven't
seen
it
yet,
I
recommend
you
to
take
a
look.

根城は八戸発祥の地であるといってよい。
1333年陸奥守北畠顕家に従って奥州下向した南部師行が顕家から北奥羽の北条残党の掃討の命を受けて拠点に選んだのが根城の地であった。平城ではあるが河岸段丘の地勢と地質の特徴を生かした防御力の高い構成をしている。惜しむらくは南側1/3が国道で分断され、また市街化が進んで全貌がわかりにくく、わずかに残った土塁などでかつてここが根城の一部だったということがわかる程度なのが残念。
北の馬淵川を北の護り、かつてはかなりの水量があったと思われる西の沢を西の守りとし、南の土塁、東の3重に掘られた堀や寺や家臣の館で守られた本丸の防御力は相当なものであったろう。
本丸のあった場所は独立の丘という風情で南にも東にも堀があり北は馬淵川、西は西の沢でかなりの標高差がある。
本丸の館、主殿は復元されている。普段執務に使用されていた常御殿、家族の住まいであった奥御殿は束柱だけ配置されているので想像するしかないが。厩は復元された客用のものと柱だけが配置された馬の生活の場所であった馬小屋と区別があったようだ。
工房や鍛冶工房は地面を掘り下げてあり、鍛冶場はともかく工房は暖房なしであったろうから、冬季の寒さを和らげる効果を期待しものか。萱葺き屋根は屋根の断熱は申し分ないから壁面積をいくらかでも減らせれば火鉢程度の熱でも作業はできたのだろう。野鍛冶場は吹き曝しであったようだ。
納屋は「なぜここに縄文の住居がある？」と思わせる外観の竪穴掘っ建て柱のつくりである。板蔵は校倉ではないが厚板を使ったしっかりしたつくりの貴重品収納庫であったようだ。井戸は埋められてはいるが発掘した際の断面図が示されている。
北側の斜面際のイチョウの老大木には落雷跡がある。おそらく避雷針替わりであったようだ。
縄文遺跡を見ても各地の城郭を見ても思うことだが、昔の人は生活の拠点選びは細心の注意を払って選定し、土地をうまく使っている。
未見の方には一見をお勧めする。
