Matsumoto Castle is a designated National Treasure, located on the plains of Matsumoto City in central Nagano Prefecture. As a hira-jiro, or castle built on the plains, it necessitated an extensive system of moats, stone and earthen walls, and gatehouses for defense.

Originally, the site was a fortress used by the Ogasawara clan around 1504. It was later taken by Takeda Shingen in 1550, and subsequently by Toyotomi Hideyoshi, who awarded it to Tokugawa Ieyasu. Ieyasu reinstated the Ogasawara clan, placing Ogasawara Sadayoshi in command. Sadayoshi named the area Matsumoto before Tokugawa Ieyasu replaced him with the trusted general Ishikawa Kazumasa.

From 1590, Kazumasa began rebuilding and expanding the castle but died in 1592. His son, Yasunaga, also known as Gemba, completed the work in 1594, including the current five-story black lacquered wooden-clad tower.

The construction inside the smaller Ko-tenshu tower and the main Tenshu tower is particularly interesting. The upright pillars in the older Ko-tenshu are rounded, while those in the main Tenshu are square, indicating different construction periods. The main keep and sub-keep towers are linked by fortified watari-yagura corridors. Both the Tenshu and Ko-tenshu feature ishi-otoshi rock-dropping hatches at the corners, indicative of their wartime construction. The southeastern corner has an open-plan yagura called the Tsukimi Yagura, or Moon-Viewing yagura, built in 1634 for moon-viewing parties, alluding to its peacetime construction.

The Tsukimi Yagura was added by Matsudaira Naomasa, Tokugawa Ieyasu's grandson, for his cousin, the third Shogun Iemitsu's planned visit, which was ultimately canceled. It is said that during a moon-viewing party in the Tsukimi Yagura, the moon can be seen three times: in the sky, reflected in the moat, and in your sake cup.


Matsumoto Castle is a collection of five separate National Treasures: the main keep, the Ko-tenshu, the two adjoining corridors, and the Tsukimi Yagura. The outer walls of the tenshu complex are covered in black lacquered shitami-itabari cladding, protecting the mud walls within and giving the castle a somber appearance, especially against the backdrop of the winter snow-capped northern Alps.

In 1872, following the collapse of the feudal system and the start of the Meiji Restoration, Matsumoto Castle was slated for demolition and sold at auction. However, citizens formed a group to save the castle, successfully preserving it for future generations. In the mid-Meiji period, the castle developed a lean, prompting civic groups to repair the tower keep. Designated a National Treasure in 1952, recent improvements have included the reconstruction of several gates and walls.

At the corner of the Taiko Yagura Mon Gate and the current entrance to Matsumoto Castle stands a large, rectangular rock about 2.5 meters high and weighing an estimated 22.5 tons, known as the Genba Stone. Named after Ishikawa Genba, the samurai lord tasked with the castle's redevelopment in 1590, the stone symbolizes power and financial strength. The story goes that Ishikawa Genba, hearing laborers complain about moving the heavy rock, swiftly executed the main complainer and displayed his head as a warning, ensuring the rock was quickly and quietly moved into place.

Matsumoto Castle, also known as Karasu-Jo or Crow Castle due to its black-walled main tower and adjoining towers resembling a crow spreading its wings, is a stunning example of Sengoku period castle architecture. It is one of only five castles designated as a National Treasure and, though off the standard tourist path, remains a remarkable destination.

  • Sasayama Castle


    Tamba Sasayama Castle, also known as Sasayama or Kirigajo (Mist Castle), is a flatland castle (hira-jiro) situated on a gentle rise in the Tamba region of Hyogo Prefecture. It was constructed in 1608 as part of Tokugawa Ieyasu's strategy to prepare for an attack on Osaka, aiming to bring an end to the Toyotomi clan. Ieyasu ordered the castle's construction using the Tenka Bushin system, engaging 20 former enemy daimyo and their forces to complete the complex within six months. This system kept the former enemies close and preoccupied, financially straining them and limiting their capacity for further conflict. The stones used in Sasayama Castle feature engravings called kokumon, indicating who made each part of the walls and preventing theft by other lords' men.
