Himeji Castle

Castles

Description

Himeji Castle is a castles in Japan, Asia. UNESCO World Heritage List: Himeji-jo dates it to 1601-1609 CE.

The finest surviving Japanese castle, known as the White Heron.

What makes it extraordinary

Dual Central Pillar Engineering

The main keep's structural integrity relies on two massive central pillars, designated as the east and west pillars. The east pillar, measuring 97 cm in diameter at its base, was originally a single fir tree. The west pillar, measuring 85 by 95 cm, is constructed of Japanese cypress. During the Shōwa Restoration (1956–1964), a new 26.4-meter cypress log was sourced from the Kiso Mountains to replace the aging west pillar; however, after it broke during the process, it was joined with another tree from Mount Kasagata at the third floor.

Massive Scale of Ikeda Expansion

The most significant expansion of the castle occurred between 1601 and 1609 under Ikeda Terumasa. This massive engineering project is estimated to have required 2.5 million man-days of labor. During this period, Ikeda demolished the previous three-story keep built by Toyotomi Hideyoshi to construct the current large-scale complex, which includes three moats and a network of 83 buildings. The resulting site covers 233 hectares, making it approximately 50 times the size of the Tokyo Dome, with walls reaching heights of up to 26 meters.

The Old Widow's Millstone

A prominent legend associated with the castle's construction involves the 'Ubagaishi' or 'Old Widow's Stone.' During Toyotomi Hideyoshi's construction of the original three-story keep in the 1580s, he reportedly ran out of building stones. An old woman, hearing of his difficulty, offered her own hand millstone despite needing it for her trade. This act supposedly inspired others to contribute stones, accelerating the project. Today, a stone covered by a wire net can still be seen embedded in one of the castle's walls, identified by local lore as that millstone.

Restoration of the White Exterior

Between 2010 and 2015, Himeji Castle underwent a comprehensive restoration to preserve its aging structures. A major result of this work was the removal of decades of accumulated dirt and grime, which had turned the roof grey. By cleaning and restoring the materials, the roof was returned to its original brilliant white color, reinforcing its nickname as the 'White Heron Castle.' This project followed a previous major restoration in the 1950s, known as the Shōwa Restoration, which cost 550 million yen and required 250,000 man-days.

Remarkable Seismic Resilience

Himeji Castle has demonstrated exceptional earthquake resistance over its nearly 700-year history. During the 1995 Great Hanshin earthquake, which caused substantial damage to the surrounding city of Himeji, the castle remained virtually unscathed. The stability of the structure was so pronounced that even a bottle of sake placed on an altar on the top floor of the keep remained undisturbed. This resilience is attributed to the castle's robust timber and stone construction, which has also survived heavy World War II bombing.

Strategic Maze and Spiral Navigation

Himeji Castle features a highly advanced defensive layout designed to confuse and delay attackers. The gates, baileys, and outer walls are organized to force an approaching army into a spiral pattern around the complex. This design significantly extends the travel distance; for instance, while the straight-line distance from the Hishi Gate to the main keep is only 130 meters, the actual path required to reach it is 325 meters. These steep, narrow passages ensured that intruders remained exposed to fire from the keep for an extended duration.

Integrated Anti-Siege Weaponry

The castle complex incorporates approximately 1,000 loopholes, known as 'sama,' shaped as circles, triangles, squares, and rectangles. These allowed archers and matchlock-armed defenders to fire upon attackers from cover. Additionally, the walls feature 'ishi-otoshi-mado' or stone-drop windows—angled chutes designed for pouring boiling oil or dropping stones on enemies below. To mitigate the risk of fire from such sieges, the exterior was coated in white plaster, which provided both its iconic 'White Heron' appearance and essential fire resistance.

Unique Internal Keep Amenities

Unlike many other Japanese keeps, the basement of Himeji's main keep contains specialized facilities including lavatories, a drain board, and a kitchen corridor. The first floor, covering 554 square meters, is known as the 'thousand-mat room' due to its capacity for over 330 tatami mats. This level was heavily armed, featuring 'bugukake' (weapon racks) that once held up to 280 matchlock guns and 90 spears. Higher floors include 'mushakakushi' (warrior hiding places) where defenders could launch surprise attacks on intruders entering the tower.

Strategic Resource Management

To survive prolonged sieges, the castle was equipped with extensive resource storage. The 'Sangoku-bori' (Three Country Moat) is a 2,500-square-meter pond located inside the castle specifically for fire prevention water storage. The complex originally contained 33 wells, 13 of which remain, with the deepest reaching 30 meters. Furthermore, the 'Shioyagura' (Salt Turret) was dedicated to storing salt, holding an estimated 3,000 bags when the castle was active. Numerous other warehouses in the Waist Quarter stored essential supplies like rice and salt.

Military Intervention for Preservation

Following the abolition of the feudal system in 1871, Himeji Castle was slated for demolition under government policy. It was spared primarily through the efforts of Nakamura Shigeto, an army colonel who advocated for its survival. Although the castle was officially designated for military use in 1872 and served as headquarters for the 10th Infantry Regiment, Nakamura's intervention prevented its destruction. A stone monument honoring his contribution stands today within the Hishi Gate, marking the transition from a functional fortress to a preserved cultural monument.
