Japan has hundreds of castles scattered throughout the country from Goryo-kaku in Hakodate, Hokkaido to Shuri Castle in Naha, Okinawa. Many Japanese castles have been restored after damage in World War II, some as recently as only 20 years ago; others are the original, historic buildings.

Japan Castle History

Much of Japan's medieval history took place behind the heavily fortified stone walls and wide moats of Japan's castles, which governed and protected the surrounding han (or, feudal domain, of which there were hundreds in Japan up until 1871) and housed the dominant samurai class.

Many of Japan's castles were built in the fifteenth and sixteenth centuries, when the country seemed constantly in a state of vicious warfare. Warlords such as Oda Nobunaga, Toyotomi Hideyoshi and Ieyasu Tokugawa are associated with many of the castles built in Japan in the medieval period known as the Sengoku Jidai or Warring States Period of around 1467-1615.

Japanese castle architecture developed at a pace during this era in response to new techniques in warfare and evolving technology - especially the arrival of firearms and cannon from Europe, which gave rise to the need for thick stone walls.

The towns which grew up around the fortresses in the Tokugawa period were peopled with merchants, artisans and entertainers, who serviced the feudal lord and his samurai community living behind the strong defenses of the castle walls.

Built at strategic points to protect the main highways connecting Japan's major cities (such as the Tokaido and Nakasendo), the cities themselves and the coastline, many old castle towns have developed into thriving, modern towns, while others have stagnated and remain backwaters.

Visiting any Japanese castle will transport the visitor back, however fleetingly to a pre-modern Japan of arms and armor, samurai and artisans.

Features of Japanese Castles

Japanese Castles, Himeji Castle.

Japanese castles have many similar forms, but layouts differ between individual castles. Shared architectural features may include a defensive moat (hori) stocked with lazy, over-fed carp; thick stone walls seen at their massive best at Osaka Castle and Nagoya Castle; shooting holes for arrows and guns; stone-dropping windows; and a complex inner layout to confuse intruders.

Apart from the stone walls, Japanese castle buildings were built of wood making them particularly prone to fire. White plaster-covered mud walls were the preferred method of protection from fire.

Japanese castles were laid out in compounds or circles (maru in Japanese). The inner circle was called the hon-maru and the second the ni-no-maru and so on. The common Japanese place name Maru-no-uchi refers to an area within the castle walls.

The tenshu was the central building in the castle and was the command post in the time of war. This part of the castle was multi-storied often with curved, tiled roofs and sumptous decoration.

Early Japanese castles such as Kumamoto Castle and Okayama Castle tended to have lacquered, black wooden walls, whereas later castles such as Hikone Castle and Himeji Castle reinforced their outer walls with white plaster coverings to protect from fire. Another theory is that black castles were built by followers of Hideyoshi Toyotomi, whereas white was predominant among the supporters of Tokugawa Ieyasu. Many Japanese castles use both colors as part of their general design for purely aesthetic reasons.

Japan's Original Castles

Japan's dozen original castles are Bitchu-Matsuyama Castle in Okayama Prefecture, Hikone Castle in Shiga Prefecture, Himeji Castle in Hyogo Prefecture, Hirosaki Castle in Aomori Prefecture, Inuyama Castle in Aichi Prefecture, Iyo Matsuyama in Ehime Prefecture, Kochi Castle in Kochi Prefecture, Marugame Castle in Kagawa Prefecture, Maruoka Castle in Fukui Prefecture, Matsue Castle in Shimane Prefecture, Matsumoto Castle in Nagano Prefecture, Uwajima Castle in Ehime Prefecture.

Japan Castles in Hokkaido

Th role of Hokkaido in Japanese history does not go back very far compared with Japan's more southern regions, and Hokkaido has never had a large population concentration, which explains the fewer number of Japanese castles in Hokkaido compared to many other areas of Japan.

Japan Castles in Tohoku

Japan's Tohoku (i.e., north-eastern) region has one original castle: Hirosaki Castle, and some interesting reconstructed castles.

Japan Castles in Kanto

The Kanto region is Japan's modern center of government and finance, but has enjoyed this status for only the past three centuries. So while the Kanto region does have some beautiful castles, they are not as plentiful as they are further west. However, the site of Edo Castle is arguably the nation's most presitigious, as it is now the home of the Emperor of Japan. The Edo Castle site, occupying the very center of Tokyo, is known as Kokyo.

Japan Castles in Kansai

The three historically important cities of the Kansai region are Osaka, Nara and Kyoto, and each has a long, distinguished history in terms of trade, politics, religion and cultural pursuits. The region's many centuries as the seat of government have endowed it with a rich castle heritage. Hikone and Himeji Castles are originals.

Japan Castles in Chugoku

The western Chugoku region of Japan has been the scene of numerous power struggles throughout Japan's history, a fact reflected in its many castles. Two of the castles in this area are originals: Bitchu Matsuyama Castle in Okayama Prefecture and Matsue Castle in Shimane Prefecture.

Japan Castles in Shikoku

The island of Shikoku has a rich castle heritage, with no less than four of Japan's twelve extant original castles open to visitors: Iyo Matsuyama Castle and Uwajima Castle in Ehime Prefecture, Kochi Castle in Kochi Prefecture and Marugame Castle in Kagawa Prefecture.

Japan Castles in Kyushu

Kyushu is the Japanese island closest to the Asian mainland and as such was the gateway to the influx of Asian cultural influence in Japan. This important role is reflected in the island's many castles, which are also testament to the domestic political struggles between Japan's old domain lords.

Japan Castles in Okinawa

Okinawa is a relative newcomer to Japan's history and its castles retain the unique style of the Ryukyu Kingdom, which enjoyed about four centuries of relative independence until the 19th century when it became officially part of Japan.

Japanese Castle Glossary

Hirajo refers to a fortress built on a plain, fujo is a lakeside castle and yamashiro is a castle on top of a hill or mountain. The latter is a common Japanese family name.

Ikkoku Ichijo ("One province, one castle") edict of 1615 - limiting one feudal domain to one castle enacted by the Tokugawa regime to limit threats to its hegemony.

Jokamachi are Japanese castle towns many of which are major towns and cities to this day.

Kura - storehouses for food, water and other provisions protected from fire with mud and plaster walls.

Mon - castle gates were the weakest parts of the castle and were protected by a courtyard style barbican. Otemon is the front gate and karametemon is back gate.

Shachi are the mythical dolphin-like creatures on a castle's roof (often made of gold), believed to protect it from fire.

Shiro - is the name for castle in Japanese though the other reading of the kanji character is -jo, which is used as a suffix, hence Nagoya Castle is Nagoya-jo and Himeji Castle becomes Himeji-jo.

Tenshu or tenshu kaku - this is the central tower, keep or donjon and was the most protected part of the castle. Arms and armor were stored here. The tenshu was usually three to five stories high, and there were often more floors inside than were visible from the outside to fool attackers.

Japanese Castles Today

There is renewed interest in Japanese castles and a number of expensive restoration projects are ongoing such as at Nagoya Castle and Kumamoto Castle. A number of replica castles have also been built in Japan since the 1960s such as Onomichi Castle in Hiroshima Prefecture.

Japanese castles were the very symbol of a town's identity in the Edo period and local authorities are realizing their potential as draws for tourists. Frequently Japanese castles will feature song and dance routines by participants in period costume in an attempt to attract the tourist yen.
