Oka Castle
The Oka Castle, now in ruins, is in Taketa, Ōita Prefecture, Japan. History Oka Castle has an extensive history. Sited on a mountaintop, it was originally built in 1185, for Minamoto no Yoshitsune. Shiga Sadatomo took control in 1332 and made many repairs and improvements. The castle was ruled by Shiga's descendants until 1586. At that point, it was taken over by Nakagawa Hideshige (in 1594) and more improvements were made, including an expansion. A main keep was added along with a palace. The Sankai turret (三階櫓), the castle's de facto Tenshu, collapsed in an earthquake, in 1769. Many of the buildings were destroyed by fire, in 1771, which had originated in the castle town. The Nakagawa ruled the castle until the Meiji Restoration The , referred to at the time as the , and also known as the Meiji Renovation, Revolution, Regeneration, Reform, or Renewal, was a political event that restored practical imperial rule to Japan in 1868 under Emperor Meiji. Although the ...

Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ...

Former Castles In Japan
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Tenshu
is an architectural typology found in Japanese castle complexes. They are easily identifiable as the highest tower within the castle. Common translations of ''tenshu'' include keep, main keep, or ''donjon''. ''Tenshu'' are characterized as typically timber-framed, having multiple stories, being seated on ''ishigaki'' (dry stone) foundations, and having individual floors delineated by surrounding tiled eaves. Further, ''tenshu'' are typically decorated with varying patterns of dormer gables (''chidori-hafu''), and are capped with hip-and-gabled roofs (''irimoya-hafu'') with ''shachihoko'' finials. Not all Japanese castles originally possessed ''tenshu'' (e.g. Sendai)'','' many well-known castles have lost their ''tenshu'' (e.g. Nijō, Edo), many have had the ''tenshu'' rebuilt on multiple occasions (e.g. Nagoya, Osaka). While both the term, ''tenshu'' and the emergence of ''tenshu'' as a distinct architectural typology occurred in the 1560s and 1570s, the early relationship ...

Palace
A palace is a grand residence, especially a royal residence, or the home of a head of state or some other high-ranking dignitary, such as a bishop or archbishop. The word is derived from the Latin name palātium, for Palatine Hill in Rome which housed the Roman Empire, Imperial residences. Most European languages have a version of the term (''palais'', ''palazzo'', ''palacio'', etc.), and many use it for a wider range of buildings than English. In many parts of Europe, the equivalent term is also applied to large private houses in cities, especially of the aristocracy; often the term for a large country house is different. Many historic palaces are now put to other uses such as parliaments, museums, hotels, or office buildings. The word is also sometimes used to describe a lavishly ornate building used for public entertainment or exhibitions such as a movie palace. A palace is distinguished from a castle while the latter clearly is fortified or has the style of a fortification ...

Keep
A keep (from the Middle English ''kype'') is a type of fortified tower built within castles during the Middle Ages by European nobility. Scholars have debated the scope of the word ''keep'', but usually consider it to refer to large towers in castles that were fortified residences, used as a refuge of last resort should the rest of the castle fall to an adversary. The first keeps were made of timber and formed a key part of the motte-and-bailey castles that emerged in Normandy and Anjou during the 10th century; the design spread to England, south Italy and Sicily. As a result of the Norman invasion of 1066, use spread into Wales during the second half of the 11th century and into Ireland in the 1170s. The Anglo-Normans and French rulers began to build stone keeps during the 10th and 11th centuries; these included Norman keeps, with a square or rectangular design, and circular shell keeps. Stone keeps carried considerable political as well as military importance and could take up ...
