Funai Castle

Overview

Funai Castle (府内城, Funai-jō) is a Japanese castle in Ōita city, on the island of Kyūshū. Construction began in 1599, in the fourth year of the Keichō era (慶長, けいちょう), during the Azuchi–Momoyama period (安土桃山時代, 1573–1603) — the decades of unification wars that ended with the establishment of the Tokugawa shogunate. The castle stands at coordinates 33.2401300, 131.6114170, close to the coast of the Bungo Channel. It is listed among the 100 Fine Castles of Japan (日本100名城, Nihon Meijō), a registry maintained by the Japanese Castle Foundation. The castle gave its name to Funai Domain (府内藩, Funai-han), the feudal territory administered from it.

History

The site is associated with Ōtomo Sōrin (大友宗麟), the daimyō (大名, だいみょう — a regional warlord) who controlled much of Kyūshū and who built a castle here in 1562. The 1599 construction date marks the beginning of the castle in the form that defines the site today, at the close of the Azuchi–Momoyama period.

The castle was originally built with several turrets, known in Japanese as yagura (櫓, やぐら). These were defensive towers set along the walls, used for storage, signalling and archery or gunnery. All of the turrets were destroyed by fire in 1743, together with the three-storey donjon (天守, てんしゅ) — the main keep, the tall central tower that served as the castle's symbolic and observational core.

Rebuilding took place in the 1800s. Two of the turrets were reconstructed in that period, and both still stand. The castle therefore preserves a mix of original and later fabric: the surviving turrets date from the nineteenth-century reconstruction, while the stone and plaster walls and the moat include original remains.

What Stands There Today

Two turrets rebuilt in the 1800s survive on the site. The original remains include sections of the stone walls and plaster walls, along with the moat.

Further reconstruction happened in the twentieth century. The covered bridge that carried traffic to the castle across its moat was rebuilt, as were three more turrets and the main castle gate. The result is a castle grounds in which nineteenth-century turrets, twentieth-century reconstructions and original earthworks and masonry stand together.

The Name in Japanese

The castle's name is written 府内城.

• Kana reading: ふないじょう
• Romaji: Funai-jō

Broken down character by character:

• 府 — read here as fu. It means a seat of government, an administrative office or a prefectural-style jurisdiction. In Japanese place names it often marks a town that served as an administrative centre.
• 内 — read here as nai. It means "inside" or "within". Combined with 府, it produces 府内 (Funai), literally "inside the administrative seat" — the name of the castle town, and the district that gives the castle its name.
• 城 — read here as jō. It means "castle". This is the standard kanji for a Japanese fortress, and it appears in the name of almost every castle in the country. When it follows another word, it is normally read jō, as in 府内城, Funai-jō.

The castle is named after Funai (府内), the place. The domain administered from the castle took the same name, Funai Domain (府内藩, Funai-han), where 藩 (han) means a feudal domain.

Visiting and Context

Funai Castle sits in central Ōita city, in Ōita Prefecture on Kyūshū. Its coordinates, 33.2401300, 131.6114170, place it near the coast, facing the Bungo Channel — the water that separates Kyūshū from Shikoku. The castle is one of the 100 Fine Castles of Japan, a list that includes both intact keeps and reconstructed or ruined sites, and that functions as a national itinerary for castle study and travel.

For readers of Japanese, the castle is a compact lesson in how Japanese names work. The word 城 (jō, "castle") attaches to a place name to form a castle name; the place name 府内 (Funai) is itself built from an administrative term plus a locational one. The same pattern recurs across the country, so learning to read 府内城 means learning to read a whole family of Japanese place and castle names.

The castle's history also illustrates a common fate of Japanese castles. Fire, war and the abolition of the feudal domains in the nineteenth century stripped many sites of their original towers, and what visitors see today is often a mixture: original walls and moats, a handful of surviving Edo-period buildings, and twentieth-century reconstructions. At Funai, the moat, the stone and plaster walls, and the two nineteenth-century turrets are the elements that carry the site's continuity, while the covered bridge, three further turrets and the main gate represent later restoration.
