Constructed in 1609 as a nationwide constrush months, this castle lacks a main keep but boasts a unique structure centered around a magnificent grand hall.
This article provides a detailed explanation of everything about Sasayama Castle, from its historical background to the charm of the grand hall restored in 2000, the highlights of its existing stone walls and moats, and access information.
The History of Sasayama Castle: A Key Point in the Toyotomi Encirclement
Background of Construction and Tokugawa Ieyasu’s Strategy
Sasayama Castle was built in 1609, nine years after the Battle of Sekigahara, a time when Tokugawa Ieyasu was consolidating the foundations of the Edo Shogunate. However, Toyotomi Hideyori was still alive and well in Osa Japan remained unpredictable.
Ieyasu’s reason for choosing Sasayama was clear. Located in the center of the Tanba Sasayama Basin, it was a crucial transportation hub where the San’in Road and the Kyoto Road intersected. By controlling the roads from Osaka to the San’in and Sanyo Toyotomi-aligned daimyo of western Japan and strategically use it as a front-line base for attacking Osaka Castle in times of emergency.
The Astonishing Speed of Construction Through a Nationwide Project
The construction of Sasayama Castle was carried out as a “Nationwide Project.” This was a large-scale civil engineering project ordered by the shogunate to be carried out by daimyo (feudal lords) throughout the country, with the aim of weaken
For the construction of Sasayama Castle, 20 daimyo from 15 provinces were mobilized. Ikeda Terumasa, lord of Himeji Castle, was appointed as the chief construction supervisor, and the layout (design) was handled by Todo Takatora, a renowned castle builders of the Sengoku period, having worked on numerous famous castles such as Iga Ueno Castle and Imabari Castle.
Amazingly, it is said that such a large castle was completed in just six months. The daimyo competed with each other to complete the construction, resulting in an exceptionally rapid completion.
Reasons why a keep was not built
Sasayama Castle did not have a keep from the beginning. There are several theories as to why, but the most plausible is that “the castle’s fortifications were too strong.” The stone walls and moats designed by Todo Takatora were extremely strong is why it was decided that a keep was unnecessary.
Instead of a keep, the Daishoin (Great Study Hall) functioned as the castle’s central facility. This reflects an emphasis on its function as a government office and symbolizes the changing role of castles during the peaceful Edo period.
Successive Lords of the Sasayama Domain
After its construction, Sasayama Castle functioned as the administrative center of the Sasayama Domain. The first lord was Matsudaira Yasushige, followed by the Matsui, Katahara Matsudaira, and Aoyama clans. The Aoyama clan, in particular, served as lords for six in the Sasayama region.
Throughout the Edo period, Sasayama Castle continued to function as an important base protecting a strategic point on the San’in Road. Although it was affected by the Sonno Joi (Revere the Emperor, Expel the Barbarians) movement at the end of the Edo period, until the Meiji Restoration.
Structure and Layout of Sasayama Castle
Characteristics of a Concentric Hilltop Castle
Sasayama Castle employs a layout style called “concentric style.” This structure features the main keep (Honmaru) at its center, with the second and third baileys arranged in concentric circles, resulting in a highly defensible design.
The castle is a hilltop castle built on a small hill called Sasayama, utilizing the difference in elevation with the surrounding plains to enhance its defensive capabilities. The Honmaru is approximately 100 meters above sea level, offering a panoramic
Highlights of the Stone Walls
One of the greatest highlights of Sasayama Castle is the high stone walls designed by Todo Takatora. The stone walls surrounding the Honmaru reach a maximum height of approximately 17 meters and were constructed using the latest technology of the time.
The stone walls utilize both “nozurazumi” (rough stone masonry) and “uchikomi-tsugi” (fitted stone masonry) techniques, allowing visitors to learn about the evolution of castle construction techniques by observing the stone-laying mets keep are particularly well-preserved, with the stonework remaining as it was over 400 years ago.
The corners utilize a technique called “sangi-zumi,” where stones are interlocked to increase strength. These stone walls were not merely defensive structures but also symbols of the daimyo’s authority.
Moat and Gate Defense System
The moats surrounding Sasayama Castle are located in the main keep, second bailey, and third bailey, forming multiple lines of defense. Even today, most of the inner moat is filled with water, allowing us to imagine its former appearance.
The gates (koguchi), which serve as entrances to the castle, have complex structures to prevent enemy intrusion. The Otemon (main gate) site, in particular, employs a masugata-koguchi (square-shaped gate) design, meaning that after passing thut must turn at a right angle. This allows for attacks on intruders from the flank.

Scale and Spatial Configuration of the Daishoin
The Daishoin consists of 15 rooms, each with a specific function. It is broadly divided into the “Omote” (front), a public reception area, and the “Oku” (inner), the lord’s private space.
The “Omote” space included the Jodan-no-ma (upper room), as well as the “Tsumesho” (waiting room) for retainers and the “Yakusho” (office) for practical work. The “Oku,” on the other hand, contained private spaces such as the lord’
