139.Sagaki-Kuniyoshi Castle Part1

An impregnable castle on the border of Wakasa Province

Location and History

Katsuhisa Awaya reclaims Castle

What is now Fukui Prefecture was divided into Echizen Province in the Northeast and Wakasa Province in the Southwest. In the 16th Century during the Sengoku Period, the Asakura Clan governed Echizen while the Takeda Clan owned Wakasa. Sagaki-Kuniyoshi Castle was in Wakasa Province near the border between both provinces. Sagaki comes from the name of the area around the castle and Kuniyoshi originates from the name of the person who first built the castle sometime before the Sengoku Period. People at that time usually called it “Sagaki Castle” and the other name “Kuniyoshi Castle” became popular later. As a result, historians and history buffs often call it Sagaki-Kuniyoshi Castle, using both names.

The location of the castle

Comparing the Asakura and Takeda Clans, Asakura were much stronger than Takeda. Asakura tried to extend their power to Wakasa Province, in response, Takeda wanted to rely on Asakura. However, Takeda’s retainers, such as one of the senior vassals, Katsuhisa Awaya, rebelled against them. Katsuhisa reclaimed an abandoned castle to prevent the Asakura Clan from invading Wakasa Province, called Sagaki-Kuniyoshi Castle. The castle was built on a steep mountain with a height at 197m near the border of Echizen Provence. People who went in or out of Wakasa Province had to pass a ridge beside the mountain, so the castle was the pivot of defense for the province. The lord of the castle usually lived in the Main Hall on the valley below the mountain, but used the mountain part when a battle broke out.

The Asakura Clan attacked Sagaki-Kuniyoshi Castle 5 times between 1563 and 1567 to crush the rebellion. However, all the attacks failed because the rebel army and the castle were so strong. The battles between them occurred as follows. The warriors, their families, and other people around the castle gathered on the mountain carrying ammunition, stones, and wood. Meanwhile, some defenders hid in ambush beside the route to the castle. When the attackers got close to the castle on the route, the defenders made a surprise attack on them. After that, when the attackers climbed up to the mid slope on the mountain, the defenders shot guns and arrows, and threw the stones and wood all together. Many of the attackers were hit and fell into the valley, forcing the rest to withdraw. In addition, when the attackers looted property and crops away from the town and fields near the castle, the defenders made a night attack on Asakura’s positions. As a result, the castle was considered to be impregnable.

Castle is involved with Battle over Country

A fortunate opportunity for Katsuhisa came in 1570 when the great warlord, Nobunaga Oda attacked the Asakura Clan. Nobunaga visited Sagaki-Kuniyoshi Castle during his invasion of Echizen and praised Katsuhisa’s military achievement. The battle between Oda and the Asakura lasted until 1573 when the Asakura Clan was defeated. Nobunaga gave Wakasa Province to one of his senior vassals, Nagahide Niwa whom Katsuhisa served. Times rapidly changed after Nobunaga was killed in the Honnoji Incident in 1582. Nobunaga’s former retainers, Hideyoshi Hashiba and Katsuie Shibata were against each other for the initiative. Katsuie was in Echizen Province while Nagahide supported Hideyoshi. That meant Sagaki-Kuniyoshi Castle became a castle at the tense border between two provinces again.

Katsuhisa’s boss, Nagahide was responsible for constructing Azuchi Castle, famously built by Nobunaga Oda. That meant Nagahide had advanced techniques for improving castles. Sagaki-Kuniyoshi Castle had basically been made of soil, but was fortified using stone walls. In the end, the battle between Hideyoshi and Katsuie happened in another place before Hideyoshi won. During the unification of Japan by Hideyoshi followed by the Tokugawa Shogunate, the castle changed hands several times. The castle still continued to be improved using stone walls, but the mountain part was eventually abandoned. Instead, only the Main Hall part in the valley was used because it was convenient for the government. In 1634 when the Sakai Clan, the lords of the Obama Domain including Wakasa Province, built the Sagaki magistrate’s office, the castle was entirely abandoned.

139.佐柿国吉城 その1

若狭国境の難攻不落の城

立地と歴史

粟屋勝久が城を再興

現在の福井県は、北東側の越前国と南西側の若狭国に分かれていました。戦国時代の16世紀、朝倉氏が越前を治め、若狭は武田氏が領有していました。佐柿国吉城は、これら両国の国境近くの若狭側にありました。佐柿という名前は城の周りの地域の名前から来ており、国吉は戦国時代より以前の何れかの時代にこの城を最初に築いた人物の名前に由来しています。当時の人々は、通常「佐柿城」と呼んでおり、もう一つの名前「国吉城」はその後によく使われるようになりました。その結果、歴史家や歴史愛好家はこの城を、これら2つの名前を使ってよく佐柿国吉城と呼んでいます。

城の位置

朝倉氏と武田氏とを比べてみると、朝倉の方が武田よりずっと強力でした。朝倉は若狭国にその勢力を広げようとしました。それに呼応して武田は朝倉に頼ろうとしたのです(度重なる国外出兵により国内が疲弊し、一揆や反乱が頻発していました)。ところが、重臣の一人、粟屋勝久を含む武田の家臣たちはそれに反発しました。勝久は朝倉氏が若狭国に侵入するのを防ぐために、廃城となっていた城を再興します。それが佐柿国吉城でした。その城は、越前国との国境近くの標高197mの急峻な山の上に築かれました。当時の人たちが若狭国に出入りするためには、その山際にある峠を通らなければなりませんでした。よって、この城は国の防衛の要だったのです。城主は通常は山下の谷にあった御殿に住んでいましたが、戦が勃発したときには城の山上部分を使ったのです。

朝倉氏の攻撃を5回撃退

朝倉氏は若狭国での反乱を鎮圧するため、1563年から1567年までの間、5回にわたって佐柿国吉城を攻撃しました。ところが、反乱軍と城がとても強力だったため、全ての攻撃は失敗に終わりました。これらの戦いは、だいたい以下の様でした。武士とその家族、他の城の周りの人々は、弾薬、石材、木材を運んで山上の城に集まります。その一方で、一部の守備兵は城に向かう道沿いに隠れて待機します。攻撃兵がその道を通って城に近づいた時、守備兵は奇襲をかけたのです。その後、攻撃兵が山を登って中腹に差し掛かった時には、守備兵は銃や矢を打ちかけ、石や木材も一斉に投げ下ろしました。攻撃兵の多くは打たれ、谷底に落下していきました。また、攻撃兵が城の近くの町から財物や穀物を略奪したときには、守備兵は朝倉の陣地を夜襲しました。その結果、この城は難攻不落と言われるようになりました。

天下を巡る戦いに関与

1570年に有力な戦国大名、織田信長が朝倉氏を攻めたことにより、ついに勝久に運が向いてきました。信長は越前侵攻中に佐柿国吉城を訪れ、勝久が率いる将兵の健闘を称えました。織田と朝倉の戦いは1573年まで続き、朝倉氏は滅亡しました。信長は若狭国を重臣の一人、丹羽長秀に与え、勝久は長秀に仕えることになりました。1582年の本能寺の変で信長が殺された後は、状況は急激に変化します。信長の部下であった羽柴秀吉と柴田勝家が主導権を巡って対立するようになったのです。勝家は越前国にいて、長重は秀吉に味方していました。これにより、佐柿国吉城は再び2つの国の緊張した国境に位置することになったのです。

勝久の主君である長秀は、織田信長によって築かれた安土城の建設では総奉行を務めました。つまり、長秀は城の拡充についての先進的な技術を持っていたのです。佐柿国吉城は基本的には土造りの城でしたが、石垣を使った城に強化されました。最終的には、秀吉と勝家の間の戦いは別の場所で起こり、秀吉が勝利しました。秀吉による、そして徳川幕府に引き継がれた天下統一の間、この城は様々な城主に受け継がれました。石垣を使った改修は続けられましたが、山上部分はやがて放棄されました。その代わりに谷にある御殿部分のみが使われるようになりました。統治のために便利だったからです。そして、若狭国を含む小浜藩の藩主であった酒井氏が、1634年に佐柿奉行所を設置したとき、城は完全に廃城となりました。

143.Mino-Kaneyama Castle Part3

The ruins were preserved as a public forest.

Features

Arriving at Main Enclosure

You will finally reach the Main Enclosure on the top. The enclosure is also partly surrounded by stone walls. The southwestern corner stone walls are said to be part of the base for the Main Tower. However, it is still uncertain if the castle had the tower.

The inside of the enclosure is a square now, but stone foundations and roof tiles for some buildings were discovered by researchers.

From there, you can see great views of the Kiso-gawa River in the north and the Nobi Plain in the west, like the lord of the castle did in the past. You will also realize the castle had a good location.

Later History

After Mino-Kaneyama Castle was abandoned, many of its stone walls were destroyed and its buildings were demolished as waste materials. In the Edo Period, the Owari Domain which owned the mountain including the ruins banned people from entering it. After the Meiji Restoration, the mountain was preserved as an Imperial Forest or a government-owned forest. Even after the castle was abandoned, it was still difficult for people to enter it many years later. The mountain was sold to the local government which is now Kani City. The city researched the ruins between 2006 and 2010 and found that they still have the features of a Shokuho style castle. The castle ruins were designated as a National Historic Site in 2013.

My Impression

When I visited the ruins of Mino-Kaneyama Castle, I pictured Tsuyama Castle which Tadamasa Mori finally built after he became the founder of the Tsuyama Domain in Mimasaka Province. Tsuyama Castle was built on a mountain with three tiers all surrounded by high stone walls. The castle was often considered impenetrable. I think Tsuyama Castle resembles Mino-Kaneyama Castle in the way that the stone walls were built. I also speculate that Tadamasa might have tried to build the strongest castle based on his experience of Mino -Kaneyama Castle.

How to get There

I recommend using a car when you visit the castle ruins.
It is about a 15-minute drive away from Kani-Mitake IC on the Tokai-kanjo Expressway. There are several parking lots including the Barbican Enclosure around the ruins
If you want to use public transportation, you can take the YAO Bus from Akechi Station on Meitetsu-Hiromi Line and get off at the Moto-Keneyamacho-yakuba-mae bus stop. It takes about 15 minutes on foot from the bus stop to get there.
To get to Akechi Station from Tokyo or Osaka: Take the Tokaido Shinkansen super express, transfer to the Meitetsu-Inuyama Line at Nagoya Station and transfer to the Meitetsu-Hiromi Line at Inuyama Station or Shin-Kani Station.

That’s all. Thank you.
