96.Obi Castle Part3

The completed castle on the Shirasu plateau

Features

Samurai Residence street and Domain school

If you walk around the eastern part of the main portion, there is the Samurai Residence street which still has its original atmosphere with stone walls, white mud walls, hedges and traditional gates. Though many of the residential buildings inside were turned into modern facilities, restaurants or residences, some of them remain as they were, for example, a former senior vassal, Ito’s residence being used as a hotel.

There is also the restored domain school building, called Shintoku Hall, one block north from the street, which provided talented people, including Jutaro Komura who was the plenary power of the Japanese side to sign the Treaty of Portsmouth to end the Russo-Japanese War in 1905. The stone walls around it are original, so when they needed to be re-piled for repairing, all stones should be numbered and re-piled to the original positions exactly as historical items.

Walking on former Castle Town

Visiting the former castle town below the castle ruins is also recommended, which is surrounded by the winding Sakatanigawa River. The town also has a similar atmosphere to the Samurai Residence street and looks more casual. For example, Ushiromahi or the Back Town street has waterways with varicolored carps swimming. Honmachi-Shonin (or the Main Town Merchant street) has old merchant houses where you can enjoy eating and shopping.

Finally, if you look at the castle ruins from the western side of the town along the river, you can see the castle was built on the edge of high and vertical cliffs which originate from the Shirasu plateau. Part of the cliffs are covered with concrete to avoid them from collapsing. Modern-day people are still struggling to maintain the castle ruins on the cliff, so the Obi Domain by the Ito Clan must have made much greater efforts to do it.

Later History

After the Meiji Restoration, most of the castle buildings were demolished. However, the layout of the castle and town including their street plans continued being used to the present time. Nichinan City launched the restoration project in 1974. After that, the area of castle ruins and town were designated as the first Preservation District for Groups of Historic Buildings in the Kyushu Region in 1977, followed by the restoration of the Main Gate in 1978 and the hall in Matsu-no-maru Enclosure in 1979. That’s why we can enjoy the well-balanced remaining and restored items in this site.

My Impression

I think Obi Castle is the completed castle on the Shirasu plateau. Building castles on the plateau was easy thanks to its nature, while maintaining them could be very difficult. Natural hazards, such as harsh weathers and earthquakes, often caused collapsing of cliffs in these castles. Because of that, other castles of the same type like Sadowara, Shibushi, Chiran were abandoned in the peaceful Edo Period. However, the Ito Clan, the lord of the castle, didn’t have any substitute land. That’s why the clan’s Obi Domain continued to build their castle and town all through the period which we can enjoy to visit right now.

How to get There

If you want to visit the castle ruins by car, it is about a 45 minute drive (through Miyazaki Prefectural Road 28) away from Tano IC on the Miyazaki Expressway. There is a parking lot for visitors in front of the castle ruins.
If you want to use public transportation, it takes about 15 minutes on foot to get there form JR Obi Station.
For visitors from Tokyo or Osaka: It may be a good idea to rent a car at Kagoshima or Miyazaki Airports after using a plane.

That’s all. Thank you.

96.飫肥城 その3

シラス台地上の城の完成形

特徴、見どころ

武家屋敷通りと藩校「振徳堂」

城の主要部分の東側(三の丸の一部)を歩いてみると、武家屋敷通りがあって、石垣、白壁、垣根、古い門などによりかつての雰囲気を残しています。敷地の中の屋敷の多くは、現代的施設、レストラン、住居に変わってしまっていますが、いくつかはそのまま残っていて、例えば、重臣の伊東氏の旧屋敷はホテルとして使われています。

通りから1ブロック北には、藩校であった振徳堂(しんとくどう)の建物が復元されています。この藩校は優秀な人材を輩出していて、1905年に日露戦争を終わらせたポーツマス条約の締結における日本側の全権大使だった小村寿太郎はその一人です。藩校を囲む石垣はオリジナルで史跡の扱いとなるため、修復のため積み直しが必要なときは、全ての石に番号が付けられ、積む際には全く同じ場所になるように作業が進められます。

旧城下町を巡る

城跡下にある旧城下町へ行ってみることもお勧めします。この区域は蛇行している酒谷川に囲まれています。城下町区域も武家屋敷通りと似た雰囲気ですが、こちらの方はよりカジュアルな感じがします。例えば、後町(うしろまち)通りには水路があり、錦鯉が泳いでいます。本町商人(ほんまちしょうにん)通りには古い商家が残っていて、そこでは食べ歩きやショッピングを楽しむことができます。

最後に、川に沿った城下町の西側から城跡を眺めてみましょう。そうすると、城はもとはシラス台地であった高く垂直に切り立った崖の上に築かれていることがわかるでしょう。崖の一部分は崩壊を防ぐためにコンクリートで固められています。現在の人々は今でも崖上の城跡を維持するのに苦心しています。伊東氏による飫肥藩は、きっと同じことをするのに更なる努力を必要としたでしょう。

その後

明治維新後、ほとんどの城の建物は撤去されました。しかし、城と城下町の構成は、町割りを含めて、現在に至るまでそのまま残ってきました。日南市は1974年に復元事業を開始します。その後、1974年には九州地方で初めての重要伝統的建造物群保存地区に指定されました。そして、大手門が1978年に、松尾の丸の御殿が1979年に復元されています。そのおかげで私たちは今日、現存しているものと、復元されたものがよく調和しているこの地を楽しむことができるのです。

私の感想

飫肥城は、シラス台地上に築かれた城の完成形だと思います。この台地上に城を築くことは、その自然の性質を利用することで簡単なのですが、それを維持することがとても難しいのです。豪雨強風や地震など自然災害が、しばしばこれらの城で崖の崩壊をもたらしてきました。そのため、佐土原志布志知覧などの飫肥城と同タイプの城は、平和な江戸時代になると廃城となるか、部分的に放棄されました。しかし、飫肥城城主である伊東氏は、そのための代替地がありませんでした。よって、伊東氏と飫肥藩は、城と町を江戸時代の間ずっと強固に築き続け、現在見られるようなすばらしい街並みになったのだと思います。

ここに行くには

車で行く場合:宮崎自動車道の田野ICから、宮崎県道28号線経由で約45分かかります。城跡の手前にビジター向けの駐車場があります。
公共交通機関を使う場合は、JR飫肥駅から歩いて約15分かかります。
東京か大阪から来られる場合は、飛行機で鹿児島空港か宮崎空港まで行って、レンタカーを借りるのがよいかもしれません。

118.Oshi Castle Part3

Other attractions around Oshi Castle

Features

Ishida Bank

I recommend visiting some historical spots near the castle regarding the Battle of Oshi Castle. One of them is Ishida Bank Ruins, about 4km away from Oshi Castle Ruins in the southeastern direction. The bank is the nearly 300m remaining one out of the 28km banks Mitsunari Ishida originally built when the battle happened.

It goes along a river in the north and a road in the south, with some pine trees planted on it, which show it is an old road. The road was actually a byway of Nikko Road during the Edo Period and is said to have been on the major Nanasendo Road before the period.

The Horikiri-bashi Bridge over the river at the edge of the remaining bank is also said to be the place where the defenders of Oshi Castle cut and drained the water inside the bank against Mitsunari.

Sakitama Ancient Burial Mounds

Another recommendation is to visit the Sakitama Ancient Burial Mounds which were built between the 5th and 7th Centuries, much earlier than Oshi Castle, but some of them are related to it. Maruhakayama-Kofun or the Round Burial Mountain was one of them and the largest round burial mound in Japan, which is 17m high and its diameter is 105m. When the Battle of Oshi Castle happened, Mitsunari put his stronghold on the mound and instructed the bank construction. You can see the top of the rebuilt three-level turret of Oshi Castle from the top of the mound, where could have been a good place for Mitsunari to see the situation of the inundation tactics. The approach to the mound is also said to have been another Ishida Bank Ruins.

In addition, Teppoyama-Kofun or the Gun Burial Mountain was involved in the history of the Oshi Domain at the end of the Edo Period. They cut one side of the mound to train their gunnery skill to prepare for their responsibility for protecting Shinagawa Batteries on Edo Bay.

Later History

After the Meiji Restoration, Oshi Castle was abandoned and its water area was turned into a modern park with office buildings but being filled in. It could be needed for modernizing the city. The city was called Gyoda, named after the district which manufactured Japanese socks, Tabi and prospered.

The park once had a baseball stadium, officials replaced it with Gyoda City Local Museum whose building looks like The Three-Level Turret the castle had. Some other buildings like a bell-tower, gates and walls were also restored around it, making them the city’s attractions.

My Impression

The result of the Battle of Oshi Castle has been said to be the only failure of Hideyoshi Toyotomi during the invasion to the Kanto Region to complete his unification of Japan in 1590, which was blamed to Mitsunari Ishida who was a foolish general. However, I think the reputation comes from being wise after the event that Mitsunari was defeated by Ieyasu Tokugawa in the Battle of Sekigahara in 1600. It is not fair. Mitsunari was the faithful executor of Hideyoshi’s order in the battle, being successful in surrounding the castle. If the defenders were not instructed by Nagachika Narita, but a magistrate from the Hojo Clan, they might have soon surrendered to Mitsunari. I think the Battle of Oshi Castle was an excellent match where Nagachika and Mitsunari took on each other.

How to get There

If you want to go there by car, it is about 30 minutes from Kazo IC or Hanyu IC on the Tohoku Expressway. there are a few parking lots around the castle ruins. It may be better to use a car if you also want to visit Ishida Bank Ruins or the Sakitama Ancient Burial Mounds as well.
By public transportation, it takes about 15 minutes on foot from Gyodashi Station on Tobu line to get to the castle ruins.
From Tokyo to Gyodashi Station: Take the Joetsu Shinkansen super express and transfer to Tobu line at Kumagaya Station.
