Kokura Castle

Overview

Kokura Castle (小倉城, Kokura-jō) is a Japanese castle in the Jōnai district of Kokura, in Kitakyushu City, on the island of Kyushu. It stands at the coordinates 33.8844440, 130.8742560, within Katsuyama Park. The castle is a five-story keep and belongs to the Continued Top 100 Japanese Castles list.

The castle's construction is dated to 1602, in the seventh year of the Keichō era (慶長, けいちょう), which places it at the very end of the Azuchi–Momoyama period, the decades of unification wars that ran from 1573 to 1603. It was built under the direction of the daimyo Hosokawa Tadaoki (細川忠興, ほそかわただおき). The site was the seat of Kokura Domain (小倉藩, Kokura-han), the feudal territory administered from the castle.

History

A castle was first built at the site in 1569, decades before the structure dated to 1602. That earlier fortification was replaced by a more substantial construction, which commenced in 1602 under Hosokawa Tadaoki. Tadaoki was a daimyo — a regional lord holding land and military power under the Tokugawa order that was consolidating at precisely this moment. The year 1602 sits in the Keichō era, and the castle is dated to the seventh year of that era.

The castle became the headquarters of Kokura Domain, the administrative unit of the surrounding territory. The domain and the castle are bound together in the record: the castle is referenced as the headquarters location of Kokura Domain.

The castle's keep is five stories tall. Among the castle keeps standing in Japan as of 2021, Kokura Castle's is the sixth tallest.

What Stands There Today

The castle stands within Katsuyama Park (勝山公園, かつやまこうえん) in Kitakyushu, in the Jōnai district. Jōnai (城内, じょうない) means "inside the castle grounds" — the name of the district preserves the old boundary of the fortification.

The castle grounds contain the Yasaka Shrine (八坂神社, やさかじんじゃ), a Shintō shrine that forms part of the site. The castle is listed among the Continued Top 100 Japanese Castles, a Japanese selection of notable castle sites.

The Name in Japanese

The Japanese name is 小倉城. Its kana reading is こくらじょう, and its romaji is Kokura-jō.

The name breaks into three kanji, read together as Kokura-jō:

• 小 — read ko here. It means "small" or "little".
• 倉 — read kura here. It means "storehouse", "granary" or "warehouse".
• 城 — read jō here. It means "castle".

The first two characters, 小倉, spell the place name Kokura: "small storehouse". The third character, 城, is the standard kanji for a Japanese castle, and it is the element that turns a place name into a castle name. When it follows another word, it is normally read jō, as in Kokura-jō. On its own, the same character can be read shiro, the native Japanese word for a castle.

The pattern is worth remembering because it repeats across the country. A castle is named for the place it guards, plus 城: 小倉 + 城, Kokura + castle. The same 城 appears in the names of castles throughout Japan, and the reading shifts between jō and shiro depending on how the name is put together.

Visiting and Context

Kokura Castle is located in Kitakyushu City, in Fukuoka Prefecture on Kyushu, and it sits inside Katsuyama Park. The Yasaka Shrine is on the castle grounds, so a visit to the site takes in both the castle and the shrine.

The castle's position in the Continued Top 100 Japanese Castles places it among the sites that Japanese castle authorities have judged worth preserving and promoting. Its five-story keep, the sixth tallest among standing Japanese castle keeps as of 2021, is the structure that defines the site today.

For readers of Japanese, the castle's name is a compact lesson. 小倉城 gives three kanji, two readings for the final character, and a place name built from "small" and "storehouse". The word 城, read jō in this name and shiro on its own, is one of the most common characters in Japanese place names and historical writing, and Kokura Castle is a clean example of how it works.
