185.Karatsu Castle Part1

The castle the Terasawa Clan built

Location and History

Area prospered with sea transportation

Karatsu Castle is located in the northwestern part of Kyushu Island, which is now Karatsu City, Saga Prefecture. The area of the city faces Genkai-nada Sea between Japan and Korea. Because of this reason, the area prospered with sea transportation including overseas trade. For example, there was Matsura Province with the port accepting the envoys from overseas nearly 2000 years ago. A warriors’ group, known as the Matsura Group, was very active using navy forces and sometimes pirates in the Middle Ages. In 1588, the ruler, Hideyoshi Toyotomi issued the Act to Ban the Piracy to control sea transportation. After that, Hideyoshi’s retainer, Hirotaka Terasawa was sent to this area to govern it. He was an excellent practical person who supported the military logistics when Hideyoshi sent large troops from Nagoya Castle near his area to Korea.

The location of the castle

Hirotaka Terasawa built Castle

Hirotaka eventually supported the Tokugawa Shogunate and became the founder of the Karatsu Domain. He also built his new home base, Karatsu Castle between 1602 and 1608. The center of the castle was built on Mitsushima-yama Mountain beside the estuary of Matsuura-gawa River. Hirotaka changed the route of the river to place the mountain and other enclosures in a line on the ground like a peninsula. The mountain was the top of the ground towards the sea. That meant enemies were not able to attack the center from the ground easily. The center was also surrounded by stone walls along the sea. Some turrets were built on the stone walls, which were probably used for monitoring the sea. Some sea ports such as Funairi-mon Gate were also built beside the estuary. On the top of the mountain, the stone wall base for the Main Tower was built. However, it is thought that the Main Tower was not built because there has been no evidence of this.

Terasawa Clan fired after Shimabara Rebellion

Hirotaka was also given a new detached territory in the area called Amakusa, in the western part of Kyushu Island by the shogunate due to his contribution. However, this caused the Terasawa Clan’s misfortune. There were a lot of masterless warriors called Ronin who were former retainers of the Konishi Clan who were fired by the shogunate. There were also many Christians which the shogunate banned people from becoming. Hirotaka oppressed both of them in accordance with the shogunate’s instructions. As a result, Shimabara Rebellion, including the people in Amakusa, happened in 1637 in the period of Hirotaka’s son, Katataka. The shogunate took Amakusa away from the Terasawa Clan after the rebellion. Katataka felt anxious and killed himself in 1647 in the end. The Terasawa Clan was fired by the shogunate because of no successor to him.

Karatsu Domain followed by Mizuno and Ogasawara Clans

After that, five clans governed Karatsu Castle and the Karatsu Domain until the end of the Edo Period. Some of the lords became famous in Japanese history. One of them was Tadakuni Mizuno who performed the Tenpo Reforms in the central government as the head of the shogun’s council of elders. Another was Nagamichi Ogasawara who was a member of the shogun’s council of elders, and devoted to the Tokugawa Shogunate till the very last moment before it fell down.

185.唐津城　その１

寺沢氏が築いた城

立地と歴史

海上交通で栄えた地域

唐津城は、現在の佐賀県唐津市にあたる、九州の北西部にあります。唐津市の市域は、日本と朝鮮の間にある玄界灘に面しています。このため、この地域は海外貿易を含む海上交通により栄えていました。例えば、２千年近く前には末盧（まつら）國があり、その国の港には海外からの使節が到着していました（「魏志倭人伝」の記述で魏の使者が上陸した地とされます）。中世には、松浦（まつら）党と呼ばれる武士団が、水軍ときには海賊を駆使して活躍しました（その中でも「上松浦党」と呼ばれる武士団がこの地域を支配していました）。1588年、天下統一を進める豊臣秀吉が海上交通を統制するために海賊禁止令を出しました。その後、秀吉の部下、寺沢広高がこの地に派遣され統治を行いました。彼は優秀な実務官僚であり、秀吉が近くの名護屋城から大軍を朝鮮に派遣した時には兵站を担当しました（他に長崎奉行を兼務していました）。

城の位置

寺沢広高が築城

広高はやがて徳川幕府を支持するようになり、唐津藩の初代藩主となりました。彼はまた、1602年から1608年の間に、新しい本拠地として唐津城を築きました。この城の中心地は、松浦（まつうら）川河口沿いにある満島（みつしま）山の上に作られました。広高はその川の流路を変え、この山と他の曲輪が半島のような陸地に一直線に並ぶようにしました。これにより、この山が海に向かって一番向こう側に配置されることで、敵が簡単に陸地を伝って城の中心部に攻められないようにしたのです。中心部はまた、海に沿った石垣に囲まれ、その石垣の上には櫓がいくつも築かれました。海上を監視するために使われたのでしょう。舟入門などの海港設備も河口の傍らに作られました。山の頂上には天守台石垣が築かれましたが、天守は建てられなかったと考えられています。天守があったことを示す証拠が見つかっていないからです。

寺沢氏は島原の乱後に改易される

広高は（関ヶ原の戦いの）戦功により、九州西部の天草に飛び地の領地を幕府から与えられました。ところが、これが寺沢氏に大きな不運を呼び込んでしまったのです。そこには、幕府により改易となった小西氏の元家臣であった浪人衆がたくさん住んでいました。またそこには、幕府が禁じていたキリシタンの人たちも多くいました。広高は、幕府の方針に従って双方を弾圧しました。その結果、天草の人たちも参加した島原の乱が1637年、広高の息子、堅高（かたたか）の代に発生します。その乱が終息した後、幕府は寺沢氏から天草の地を取り上げました。堅高はそれを恥辱に感じ、1647年にはついに自殺してしまいます。寺沢氏は、跡継ぎがいないという理由で幕府により改易されました。

水野氏、小笠原氏などが引き継ぐ

その後、５つの大名家が唐津城と唐津藩を江戸時代末まで統治しました。そのうちの何人かは日本史の中でも有名です。例えば、水野忠邦は老中首座として、中央政府で天保の改革を進めました（そのときは浜松城に移っていました）。また、小笠原長行（ながみち）は老中の一人でしたが、徳川幕府が倒れるそのときまで忠節を尽くしました（奥羽越列藩同盟にも参画）。

136.Torigoe Castle Part3

I am thankful to live in the safety of modern Japan.

Later History

The ruins of Torigoe Castle had been abandoned for a long time after the Ikko uprising was defeated. The excavation was conducted between 1977 and 2002, while the ruins were designated as a National Historic Site in 1985. The development as a historical park and the restoration of some castle structures were also done between 1991 and 2002. That’s why we can see the ruins as the monument of the Kaga Ikko uprising.

My Impression

When I visited Torigoe Castle Ruins, I thought the castle was exactly like those that the warlords built. This proves the Kaga Ikko uprising really had religious, political and even military power. In other words, people at that time needed to protect themselves. People in the present time usually live safely without these concerns, at least in Japan. I learned that this is partly due to the precious sacrifice of the Ikko uprising people. I also recommend seeing the ruins as a good example of mountain castles during the Sengoku Period.

How to get There

I recommend using a car when you visit the ruins.
It is about a 30-minute drive away from Komatsu IC on the Hokuriku Expressway. You can park at the parking lot located near the top of the mountain.
If you want to use public transportation, you can take the Hokutetsu-Kaga Bus on the Mugiguchi Line from Komatus Station and get off at the Misaka bus stop. It takes about 30 minutes on foot from the bus stop to get there.
To get to Komatsu Station from Tokyo: Take the Hokuriku Shinkansen super express, transfer to the limited express on the Hokuriku Line at Kanazawa Station.
From Osaka: Take the Thunderbird limited express

That’s all. Thank you.
