38.Iwamura Castle Part2

The castle ruins are worth to climb

Features

Long Trail to Top of Mountain

Today, the ruins of Iwamura Castle have been well developed for visitors. If you climb up from the foot to the top of the mountain, you can understand how strong the castle was. There is the partly restored Main Hall for the lord with the Drum Turret on the foot. From the foot, you will need to climb to the top for about 800 m long and about 170 meters high. Only stone walls and foundations of the castle remain on the mountain. However, if you have a smartphone, you can see the re-produced image using CG and hear the explanation (however only available in Japanese) at each signboard by scanning the QR code on it.

Lots of Gateway to protect Castle

The first part of your climb may be very tough because the trail is steep and it’s on a winding road which is as long as 500m, which is called Fijisaka. You will pass three defense points called Hatsu-mon Gate, Ichi-no-mon Gate and Toki-mon Gate before reaching the Main Gate Ruins. Enemies in the past must have also found it tough when they attacked the castle through the same route.

Main Gate, Pivot for Defense

The Main Gate was the pivot for the defense, which had a complex system protecting the castle. The Three-level Turret was built beside the gate, which was also the symbol of the castle. The current trail goes around to the left, but visitors in the past had to go across a bridge called the Tatami-bashi which went straight to the gate. The floor boards of the bridge could be removed like tatami mats (traditional mats in Japanese homes) if enemies were to attack. Moreover, visitors had to turn left on the bridge when they entered the gate. If visitors were enemies, they would have been stuck and counterattacked from the turret and gate.

After passing the Main Gate Ruins, the trail becomes easier, and the area around it is relatively spacious. There used to be some warriors’ houses in the past. You will go though the area seeing the Hachiman Shrine Ruins on the left and the Kirigai Well which was said to never run out of water on the right. There were two routes in the past to reach the Main Enclosure on the top, the one from the Second Enclosure and the other from the Eastern Enclosure. However, the Second Enclosure is not well developed for visitors now, so most visitors usually go towards the Eastern Enclosure instead.

Six Tier Stone Walls, Highlight of Castle

One of the highlights of the castle is the Six Tier Stone Walls of the Main Enclosure beside the Eastern Enclosure. They look so great. In fact, these stone walls had originally been a single high stone walls, but the other tiers were added later to prevent them from collapsing. Other than that, the Main Enclosure is all surrounded by great stone walls, especially, the high stone walls on the western side are also so nice.

38.岩村城 その2

登り甲斐がある城跡です。

特徴、見どころ

長く続く山頂への道

今日、岩村城跡はビジター向けによく整備されています。もし、山麓から山頂の方に向けて歩いていかれれば、この城がどんなに強力だったかわかると思います。山麓には太鼓櫓とともに城主御殿が一部復元されています。山麓から山頂までは、距離で800m、比高で170mを登っていく必要があります。山の上には城の石垣と基礎部分だけが残っています。ただ、もしスマートフォンをお持ちでしたら、説明板にあるQRコードをスキャンすることで、CGによる再現イメージを見て、説明音声を聞くことができます。

いくつもの関門

前半の登りは結構つらいかもしれません。急で且つ曲がりくねっている山道が500mも続くからです。この部分は藤坂と呼ばれています。ここの区間では、初門、一の門、土岐門という3つの防御拠点を通り過ぎ、追手門跡にたどり着きます。過去に城を攻めた敵も、同じルートから攻めたときには大変な困難を感じたはずです。

防衛の要、追手門

追手門は防衛の要で、城を守るための複雑な仕組みを備えていました。三階建ての櫓が門のとなりにあり、城のシンボルにもなっていました。現在の山道は左側に回り込んでいますが、過去の城への訪問者は畳橋と呼ばれた門に真っ直ぐ伸びる橋を渡っていきました。その橋の橋板は、敵が攻めてきたときには畳のように取り外せるようになっていました。更に橋の上で左折し、門に入って行かなければならなかったのです。もしそれが敵だったら、その地点で釘付けとなり、櫓と門の両方から反撃を受けたことでしょう。

追手門跡を過ぎた後は、山道はやや緩やかになり、その周辺は比較的広々としています。かつてはここに武家屋敷が並んでいました。そこから、左側に八幡神社跡、右側に水が枯れることがないといわれる霧ヶ井という名の井戸を見ながら進んでいきます。頂上にある本丸に行くには2つのルートがあります。一つは二の丸を通り、もう一つは東丸を通ります。しかし、二の丸はビジター向けにはあまり整備されていないため、ほとんどの人は東丸の方向かって歩いていきます。

最大の見どころ、六段石垣

この城の最大の見どころの一つは、東丸のとなりの本丸の六段石垣でしょう。見事な石垣です。実は、この石垣はもともと一段の高石垣だったのですが、崩壊を防ぐために後に他の段が付加されたのです。それ以外にも、本丸は素晴らしい石垣によって囲まれています。特に西側の高石垣は、見ものです。

142.Naegi Castle Part3

The warriors maintained the castle for a long time.

Features

Umaarai Rock, Second Enclosure and Photo spot

The map around the castle

If you climb down from the top on another route, you can see the biggest rock around, called Umaarai-iwa, just below the Main Tower base, whose perimeter is about 45m. It should make you feel power of nature.

The Second Enclosure is far below from the top, where the Main Hall for the lord was in the past. The hall was built hanging out from the enclosure by also using the Kake-zukuri method.

In addition, if you want to take in a great whole view of the ruins, you can take another return route to the photo spot.

Later History

After the Meiji Restoration, Naegi Castle was abandoned and all the buildings of the castle were demolished. The mountain the castle was located on was returning to nature, being covered with trees. However, the ruins of Naegi Castle were designated as a National Historic Site in 1981 because the foundation of the castle ,including its stone walls, remained intact. The ruins recently became popular due to their unique features, such as the combination of natural rocks and stone walls, and great views. Some trees were cut down to see the main portion of the ruins clearly for visitors.

My Impression

It is said that there were six types of stone walls in Naegi Castle, ranging from the oldest one using natural stones to newer advanced ones. That meant the Naegi Domain continued to build or repair them under the severe living condition for over 250 years in the peaceful Edo Period. I was very impressed by that.

The stone walls piled in a way called Tani-zumi or the Form of a Vally, near the entrance of the ruins
The stone walls piled in a way called Uchikomi-hagi like piling roughly processed stones, at the Northern Gate Ruins, in the back of the Large Turret Ruins
The stone walls piled in a way called Kirikomi-hagi like piling precisely processed stones, at the Large Turret Ruins
The stone walls piled in a way called Nozura-zumi like piling natural stones, around the starting point to the top

I remember an example of a similar case to Naegi Castle, called Oka Castle in the Kyushu Region. The castle was likewise built on a rocky mountain. It was very defensive but hard to live in, so the warriors immediately disappeared after the Meiji Restoration.

How to get There

I recommend using a car when you visit the castle ruins.
It is about a 10-minute drive away from Nakatsugawa IC on the Chuo Expressway. There are several parking lots around the ruins.
If you want to use public transportation, you can take the Kita-Ena-Kotsu Bus bound for Tsukechikyo-Kuraya-Onsen or Kashimo-Sogo-jimusho from Nakatsugawa Station and get off at the Naegi bus stop. It takes about 20 minutes on foot from the bus stop to get there.
To get to Nakatsugawa Station from Tokyo or Osaka: Take the Tokaido Shinkansen super express and transfer to the Chuo Line at Nagoya Station.

That’s all. Thank you.
