You can sense the original state of the castle.

Spot for seeing both Main Tower and Main Gate

As a visitor to Kochi Castle today, you will likely enter the remaining Main Gate first, where you can also see the remaining Main Tower over there. In fact, this is a very rare spot where you can see the two kinds of remaining buildings together in Japan.

From Suginodan Enclosure to Iron Gate Ruins

After entering the gate, you can climb on the stone steps to the Suginodan Enclosure where the statues of Kazutoyo Yamanouchi’s wife, called Chiyo, and a horse stand. These statues show that she spent her dowry to buy a fine horse for Kaszutoyo’s parade which was the chance for his promotion. You can also see the great high stone walls of the Third Enclosure above.

If you go further by climbing the stone steps, you will be at the ruins of the Iron Gate which was an important point for defense. The gate was next to the Third Enclosure and led to the Second Enclosure. That’s why the tricky system which could lead enemies to the false gate to the Main Tower, called Tsumemon, was built.

Third and Second Enclosures

The Third Enclosure is the largest enclosure in the castle where a large building for ceremonies was in the past. In addition, the stone walls of Chosogabe’s period were found there by excavation.

The Second Enclosure had another Main Hall for the lord where he usually lived, as the hall in the Main Enclosure was too small for daily life. However, the Second Enclosure is just a square now.

Main Enclosure, almost same condition as original

You can finally reach the Main Enclosure by crossing the remaining Tsumemon Gate from the Second Enclosure. Surprisingly, this enclosure is in almost the same condition as its original, with the 11 remaining buildings. This is also the only spot where the original Main Tower and Main Hall remain at the same place in Japan.

You will need to enter the Main Hall first to reach the Main Tower as they are directly connected to each other. The hall is not large because the space of the enclosure is limited, but important ceremonies for the domain were held there.

The Main Tower has four layers and six stories, that means two of the stories are attics (3F and 5F). Its style is called the lookout tower type. In the case of Kochi Castle, there is the small two-layer lookout tower on the large two-layer turret with a hip-and-gable roof. The tower also has decorations like Chinese style gables and triangular shaped gables on the roof and a veranda with the lacquered handrail at the top floor. It looks traditional and very beautiful.

84.高知城 その2

昔のままの城を感じることができる場所です。

特徴、見どころ

天守と追手門が同時に見れる場所

今日高知城を訪れる観光客の方は、最初は現存する追手門から入って行かれるのではないでしょうか。ここからは、向こうの方に現存する天守も眺めることができます。実は、この2種類の現存する建物を一緒に見ることができるのは大変珍しいことなのです(あとは丸亀城くらいかと思います)。

杉ノ段から鉄門跡へ

追手門から入って石段を登っていくと杉ノ段に至ります。そこには、山内一豊の妻、千代と一頭の馬の銅像があります。この銅像は、彼女が、夫の一豊が参加する馬揃えのために持参金をはたいて良馬を購入したことで、一豊が出世するきっかけをつかんだというエピソードを示しています。ここから見上げると、三ノ丸の素晴らしい高石垣が目に入ってきます。

更に石段を登って進んでいくと、鉄門(てつもん)跡に着きます。ここは防衛上重要な地点でした。この門は、三ノ丸のとなりにあり、二ノ丸へ向かう経路の途中にあります。そのために、敵を本丸への門と勘違いさせるような詰門を使った巧妙な仕掛けがここに作られたのです。

三ノ丸と二ノ丸

三ノ丸は、この城では最も大きな曲輪であり、かつては儀式のために使われた大きな御殿がありました。発掘により、長宗我部時代の石垣がここから見つかっています。

二ノ丸には、本丸以外のもう一つの領主の御殿があり、領主は通常ここに住んでいました。本丸にあった御殿は日常生活をおくるには狭すぎたからです。現在の二ノ丸は広場となっています。

ほとんど元のままの本丸

二ノ丸から現存する詰門を渡って行くと、ついに本丸に到着します。驚くべきことに、本丸には元あった状態とほとんど変わらないまま、11もの建物が残っています。また、同じ場所にオリジナルの天守と本丸御殿が残っている日本で唯一の例でもあります。

天守に至るには、まず最初に御殿の方に入る必要があります。双方が直接つながっているからです。この御殿は、本丸の大きさが限られているため、確かにそんなに広くありません。しかし、藩にとって重要な儀式はここで行われました。

天守は四層六階です。つまり、六階のうちの二階は屋根裏部屋となっています(3階と5階)。この天守は、望楼型と呼ばれる形式です。高知城の場合は、入母屋屋根を備えた大型の二層櫓の上に、小型の二層望楼が乗っかっています。また、天守の屋根には唐破風や千鳥破風、最上階には漆塗りの欄干付きの回り縁といった装飾がされています。古い伝統と美しさ両方が見られる天守です。

84.Kochi Castle Part1

The Yamanouchi Clan’s unique castle

Location and History

Pre History of Kochi Castle

Kochi City originated from the name Kochi Castle and is the capital of Kochi Prefecture on Shikoku Island. Kochi Castle is one of the most popular tourist spots of the prefecture. It has many remaining castle buildings including the Main Gate, the Main Hall, and the Main Tower. The castle was built on a low mountain called Mt. Otaka-sakayama, but it is uncertain when it was first built. In 1588, Motochika Chosogabe, the lord of Tosa Province, what is now Kochi Prefecture, moved his home base from Okoh Castle to Kochi Caste, which was called Otaka-sakayama Castle at that time. However, he moved again to Urado Castle after only a three-year stay in Otaka-sakayama Castle. This could be because the area received a lot of rain but had poor drainage.

Kazutoyo Yamanouchi built Kochi Castle

In 1601, Kazutoyo Yamanouchi was promoted by the Tokugawa Shogunate to a new lord of Tosa Province and became the founder of the Tosa Domain. He tried to rebuild and live in Otaka-sakayama Castle which had enough space to build the castle town. The castle was rebuilt with advanced technology at that time, such as building stone walls and large-scale buildings. After the completion of the castle, it was renamed Kochi Castle. As a result, the Yamanouchi Clan governed the castle and the province all through the Edo Period.

Features of Kochi Castle

Kochi Castle had several interesting features. First, the castle had a lot of stone troughs to allow for proper drainage if it rained a lot. Such a system was very rare for castles in Japan and can even now be seen when you visit the castle.

Secondly, the castle had an old-style Main Tower, called the lookout tower type, for the period of its construction. It is said that Kazutoyo wanted to build the Main Tower resembling the Main Tower of Kakegawa Castle, where he lived before he went to Tosa Province. For this reason, when people in Kakegawa restored the Main Tower of Kakegawa Castle in the present time, they used the design plans of the remaining Main Tower of Kochi Castle.

Most of the castle buildings including the Main Tower were unfortunately burned down by a great fire in 1727. When the Tosa Domain rebuilt the castle after the fire, they restored the Main Tower in 1749 in a way which was almost the same as the original one, not using a new style. This could be because the shogunate just allowed the domain to use the original style even for rebuilding. It is also said that the warriors in the domain still loved the style of their founder, Kazutoyo. The Main Tower also didn’t stand on a stone wall base and was connected directly to the Main Hall in the Main Enclosure on the top of the mountain. It is thought that this is also one of the styles of old castles.

The castle also had a feature using both buildings and natural terrain of the mountain for defense. If enemies attacked the castle to reach the Main Tower, they had to pass through the Suginodan Enclosure and the Second Enclosure which were built around the slope of the mountain. In addition, if enemies passed the Iron Gate before the Second Enclosure, they could be near the Main Tower and see the Tsumemon-Gate which looked like the gate to the tower. However, it was just a bridge between the Main Enclosure and the Second Enclosure, which the enemies could never go across from that point. This is a tricky system to prevent enemies from reaching the center of the castle.
