13.Shirakawa-Komine Castle Part2

the ruins of the castle were turned into a park. Officials changed their policy for developing the ruins because the detailed drawings of the castle buildings were left by Sadanobu Matsudaira. They were wondering if the castle would be restored to its original condition. That would be the first attempt in the way large castle buildings are rebuilt in the present time of Japan.

Later History

During the Meiji Era, the ruins of the castle were turned into a park in which the baseball stadium was constructed in during the Showa Era. Officials changed their policy for developing the ruins because a lot of citizens complained and the detailed drawings of the castle buildings were left by Sadanobu Matsudaira. They were wondering if the castle would be restored to its original condition. That would be the first attempt in the way large castle buildings are rebuilt in the present time of Japan.

However, there was a big problem with the law. Japan’s Building Standard Act has very strict restrictions on wooden buildings which are over 13m tall. According to this law, new large old-style wooden buildings like the Shirakawa-Komine castle turret are not allowed to be built. So officials continued the restoration of the turret not as a building, but as a structure that would be allowed by the law. It was finally completed in 1991. However, another problem occurred as the government made the most part of the turret inaccessible to visitors, because it was not “a building”. At last, the law had the provisions to be exempt for historical buildings in 1993. The three story-level was finally opened to visitors.

Features

Castle Ruins still look Strong

Today, if you stand in front of the ruins of Shirakawa-Komine Castle, called Shiroyama Park, you will be impressed by its wide remaining stone walls and the slim restored three-level turret on the top. The entrance of the park was that of the second enclosure, which had Taiko (drum)-mon Gate. The enclosure has become an open space where people can enjoy relaxing and exercising. It is also partially used by public facilities such as Komine-jo(castle) History Museum and a tea house.

The main portion of the castle ahead still looks very strong, which is surrounded by the inner moat and two-tiered high stone walls. These tiers consist of the main enclosure on the top and the surrounding Take (bamboo)-no-maru Enclosure. You need to go across the earthen bridge over the moat and the ruins of Shimizu(pure water or spring)-mon Gate to enter it. The gate was the largest one in the castle and Shirakawa City is actually planning to restore it by 2026 (as of January 2024). Next, if you climb the stone steps and turn right on the Take-no-maru Enclosure, you will see the three-level turret close by.

Good Combination of restored Turret and Gate

You can also see Mae-gomon (meaning the front gate) next to the turret which has been restored in the original way since 2004, following the turret. The set of the turret and the gate looks very good and shows the authority of the castle. If you enter the gate, you will be at the main enclosure, which is an empty space but had the main hall for the lord in the past.

The three-level turret stands on the northeastern corner of the enclosure. Its three floors are simply built with the 11.7meters (6 Ken in the traditional Japanese unit of length) square of fist floor, the 7.8 meters (4 Ken) square of the second one and the 3.9 meters (2 Ken) square of the top one. Each level also has simple roofing and has two-tones of colored walls from white plaster and black-painted lumber. Overall, the tower looks very beautiful with its good design and color arrangement.

Interior of Turret is completely restored as well

You can enter the turret from the inside of the enclosure. From the processes of restoring this turret, officials always stay inside and monitor the safety of the visitors. For example, only five visitors can stay above the first floor at the same time under the current regulations. That’s because the turret was restored exactly in the same way as the original one except for the minimum safety equipment and explanation boards. If you walk around the first floor, you will find that it is not bright and many columns standing inside. Some of the columns came from pine trees of Inari Mountain, one of the hills where the severe battles occurred in 1868 during the Boshin War. That’s why you can see the bullet marks, caused by the war, on one of them.

You can also see the defense systems like machicolations, loopholes and bay windows at the northern and eastern sides of the floor. These sides face the outsides of the enclosure, which could have been attacked by enemies.

If you want to go to the second and third floors, please be careful when climbing the very steep stairways, but you can use the handrails and ropes.

As you go above, the floor becomes smaller and you may feel you are in a box on the top floor. The floor also has defense systems similar to other floors, where you can understand the turret is very practical for battles. In addition, you can see views of the outside through the lattice windows of the floor.

13.白河小峰城 その2

城跡は公園となりましたがその後、城跡整備の方針は変更されることになりました。松平定信により城建物の詳細図面が残されていたからです。城を元通りの姿に戻せないか検討が始まったのです。これは現代の日本において、城の大型の建物を元通りに再建する最初の試みでした。

その後

明治時代には城跡は公園となり、昭和時代には野球場が建設されたりしました。しかしその後、城跡整備の方針は変更されることになりました。市民から多くの要望があり、また松平定信により城建物の詳細図面が残されていたからです。城を元通りの姿に戻せないか検討が始まったのです。これは現代の日本において、城の大型の建物を元通りに再建する最初の試みでした。

ところが、これには法律上の大きな問題がありました。日本の建築基準法は、13mを超える高さの木造建築物に厳しい規制を課していたのです。この法律によれば、白河小峰城三重櫓のような大型の古い形式の木造建築物を、新しく作ることはできませんでした。そのため、この櫓は建築物としてではなく、工作物として復元作業が続けられました。この扱いであれば、法律の許容内でした。そしてついに1991年に完成となりました。しかし、また新たな問題が発生します。政府当局が、櫓のほとんどの部分にビジターを入れてはいけないと言ってきたのです。「建築物ではないから」が、その理由でした。最終的には1993年に、歴史的建造物に対する例外規定ができたことで、三重櫓は全面的にビジターに公開されることになりました。

復元された三重櫓

特徴、見どころ

今でも威厳のある城跡

現在、城山公園と呼ばれる白河小峰城跡の前に立ってみると、今でも広大に城を覆っている石垣群の上に、スリムに復元された三重櫓が乗っかっていて、とても印象的です。公園の正面入口は、かつては二の丸入口で、そこには太鼓門がありました。二の丸は今では広場になっていて、くつろいだり、運動したりすることができます。敷地の一部には、小峰城歴史館、二の丸茶室などの公共施設があります。

その先にある城の主要部分は、今でも内堀と二段の石垣に囲まれていて、とても強そうに見えます。この二段の構えは、上の方にある本丸を下の方の竹の丸・帯曲輪が囲んでいる形になっています。主要部分に入るには、堀を渡る土橋と清水門跡を進んでいく必要があります。この門は城では最大の門でした。実は白河市は2026年までにこの門を復元する予定でいます(2024年3月時点の情報)。次に右に曲がって石段を登っていくと竹の丸に至りますが、そこでは三重櫓が間近に迫って見えます。

復元された櫓と門のコンビネーション

三重櫓のとなりには、櫓に続き2004年にオリジナルと同様に復元された前御門も見えます。この櫓と門の取り合わせはとても見栄えがして、城の権威をも高めています。門を入っていくと本丸となります。今は広場となっていますが、かつては城主のための御殿がありました。

三重櫓は本丸の北西隅に立っています。その構成はシンプルに正方形の3フロアを積み上げていて、1辺11.7m(6間四方)の一階、1辺7.8m(4間四方)の二階、そして一辺3.9m(2間四方)の三階から成っています。それぞれの階には簡素な屋根が付き、壁は白い漆喰と黒い板壁の2色構成です。そのシンプルさがかえって櫓を美しく見せています。

本丸内部から見た三重櫓

外も内も元通りに復元された三重櫓

櫓には本丸の内側から入っていきます。この櫓を復元したときの経緯もあって、係員が櫓の内部に常駐していて、ビジターの安全を常にチェックしています。例えば、規定によって一階から上には同時に5人のビジターしか入れないことになっています。この櫓が、最小限の安全設備と説明板を除き、オリジナルのものと全く同様に復元されているからです。一階を歩いてみると、中はあまり明るくなく、柱が多く立っていることに気付かれるでしょう。その柱には、1868年の戊辰戦争のときに激戦地となった稲荷山の松の木が使われています。そこには、戦争のときに生じた弾痕を見ることができます。

また一階の北側と東側には石落とし、狭間、格子窓といった防御システムがあります。この両サイドは本丸の外側を向いていて、敵の攻撃を受ける可能性がありました。

二階と三階に上がるときには、とても急な階段を登ることになるので気を付けて下さい。但し、復元のときに付けられた手すりとロープを使うことができます。

上の階に行くに従い、フロアは狭くなり、最上階ではまるで箱の中にいるようです。この階にもまた他の階と同じような防御システムがあります。この櫓は実戦的に作られたということがわかると思います。格子窓を通じてということにはなりますが、外の景色を見ることもできます。

13.Shirakawa-Komine Castle Part1

An epochal event happened to the castle in 1627 when Nagashige Niwa came there as the founder of the Shirakawa Domain. Nagashige was a son of Nagahide Niwa who was in charge of building Azuchi Castle, the fist modernized castle in Japan, under Nobunaga Oda. He was a master of castle constructions by following the know-how and connection from his father.

Location and History

Yuki Clan builds Caste as their Branch

The Shirakawa area, which is modern day Shirakawa City, has been the entrance of the Tohoku Region. There was a famous barrier called Shirakawa-no-seki (meaning the Shirakawa Barrier) in the area during the Ancient Times. Shirakawa-Komine Castle was first built by the Yuki Clan during the 14th Century and simply called Komine (meaning small mountain) Castle. The clan had lived in another castle called Shirakawa Castle. They originally came from the Kanto Region to the south and settled there during the 13th Century. Komine Castle was built on a hill beside Abukuma River as their branch castle to protect their home. Komine Castle would later become more popular and also be called Shirakawa Castle. To avoid confusion, historians and officials classify them and call the second Shirakawa Castle, Shirakawa-Komine Castle.

Nagashige Niwa greatly modernizes Castle

The Yuki Clan was unfortunately fired by the ruler, Hideyoshi Toyotomi during his unification of Japan at the end of the 16th Century. After that, Shirakawa-Komine Castle was followed by the Uesugi and the Gamo Clans as their branch. It was said that the basic structures of the castle were built by them but were still mostly made of soil. An epochal event happened to the castle in 1627 when Nagashige Niwa came there as the founder of the Shirakawa Domain. Nagashige was a son of Nagahide Niwa who was in charge of building Azuchi Castle, the fist modernized castle in Japan, under Nobunaga Oda. Nagashige joined the Western Alliance in the decisive battles in 1600 when he was a lord in the Hokuriku Region, against the Eastern Alliance which won and established the Tokugawa Shogunate. That’s why Nagashige was once fired by the shogunate. However, he was appointed as an independent lord again in 1603. One of the reasons may be that he was a master of castle constructions by following the know-how and connection from his father.

Nagashige renovated the castle as his home between 1629 to 1632. The shogunate also expected him to build a strong castle to monitor many non-hereditary feudal lords in the Tohoku Region to the north. Nagashige built stone walls, water moats, turrets and residences on the existing castle. He also changed the flow of the Abukuma River from the west to the north to make the castle more spacious and more defensive from that direction. The three-level turret was built at the northeastern corner of the main enclosure to monitor the Oshu Road to the north, too. It was 14m high and the symbol of the castle. It was also called the Main Tower in the first stage of the castle, but eventually stopped. This was probably done after the Main Tower of Edo Castle, the shogun’s home, was burned down in 1657 and not rebuilt. The Shirakawa Domain might have considered the relationship with the shogun.

Sadanobu Matsudaira starts Reform

The castle and the domain were followed by several hereditary feudal lord families such as the Sakakibara, Honda, Matsudaira (Okudaira), and Matsudaira (Yuki) Clans. The Tohoku Region including the Shirakawa area was not fertile at that time, often suffering damages from cold weather, droughts, and floods. Therefore, the Shirakawa domain was always having financial problems. In 1783, Sadanobu Matsudaira (Hisamatsu) became the lord and started to reform the government. His basic policies were to simplify lives and save money. He encouraged academics and military arts to the warriors, and more production to the farmers. In particular, his social policies were excellent. For example, he saved farmers even in the Tenmei Great famine during the 1780’s and supported their infants. He finally became the head of the members of the shogun’s council of elders in 1787 to lead Kansei Reforms in the central government. He also made detailed drawings of the castle buildings which would later give us an unexpected fortune.

Castle falls in Battle of Shirakawaguchi

The Abe Clan finally followed the domain in 1823. However, Masato Abe, who was involved in the central government, but was punished due to his policy’s failure in 1866. As a result, the Shirakawa area was like terra nullius (officially owned by the shogunate), which would bring a big misfortune to the castle. In 1868 during the Meiji Restoration, the new government, which defeated the shogunate, and many domains in the Tohoku Region, which still supported the shogunate, confronted each other, known as the Boshin War. The new government army’s first target was the Shirakawa area, the entrance of the region. The alliance of the Tohoku domains had to protect the area and Shirakawa-Komine Castle together.

However, the castle had weak points to the south, the direction from which the army was coming. There were three hills (Inari, Tateishi, and Raijin Mountains) around 1km from the castle, which could be used for cannons to target it. In addition, the new government army were equipped with more advanced guns than the alliance troops. The alliance was also undisciplined without excellent commanders. On the 1st of May, the Battle of Shirakawa-guchi occurred. The army occupied these hills and fired at the troops and the castle. The alliance was eventually defeated and the castle was captured in only one day. Many of the castle buildings including the three-level turret were also burned down. After that, the alliance tried to get the castle back several times but failed each time. One of the reasons may be the strong defense of the castle to the north which the alliance withdrew to and was striking back from.
