Matsumoto Castle

Matsumoto Castle, located in Matsumoto City, Nagano Prefecture, is a National Treasure with one of Japan’s oldest surviving keeps. Its elegant black-and-white exterior blends Sengoku-period defensive design with Edo-period refinement, making it widely known as a premier Japanese castle.

One of the Twelve Original Surviving Keeps — Among Japan’s Oldest, and a National Treasure

Built from the late Azuchi–Momoyama into the early Edo period, Matsumoto Castle’s keep is one of Japan’s oldest surviving keeps. It is counted among the nation’s scarce “Twelve Original Surviving Castle Keeps,” and is especially rare for preserving a complete five-tier, six-story structure.

In 1936 it was designated a National Treasure, and the castle site as a whole is a National Historic Site. It is also listed among the “Japan’s Top 100 Castles,” firmly establishing its reputation.

Matsumoto Castle is a flatland castle, often grouped with Nijō Castle and Hiroshima Castle as one of the “Three Great Flatland Castles of Japan.” Unlike mountain fortresses, it developed closely with the surrounding town.

Surviving from the Sengoku era to the present, Matsumoto Castle continues to embody the evolution of Japanese castle architecture and cultural value.

Black-and-White Brilliance — The Exterior Beauty of Matsumoto Castle Keep

A key allure of the keep is its exterior: lower tiers are clad with black lacquered siding, while upper tiers are finished with white plaster, repeating in layers.

The jet-black wood imparts strength and tension, while the white plaster emphasizes lightness and purity. Together they form a distinctive aesthetic that captivates visitors.

Coupled with its five-tier, six-story scale, the tower seems to soar skyward. For the best views, stroll around the outer moat and admire it from multiple angles.

Looks Like Five Stories—but There Are Six! Ingenious Structural Design

From outside, the keep appears to have five stories, yet it actually contains six. This “five-tier, six-story” configuration is a signature feature that surprises many visitors.

Matsumoto Castle is a connected compound keep, combining the main and smaller keeps with linking turrets and corridors. Unlike a stand-alone tower, this composition enhances both defense and usability.

A five-story appearance with six interior floors, plus a compound of multiple turrets—this ingenuity is one of Matsumoto Castle’s defining highlights.

The Invisible Level — The Mysterious “Dark Room” on the Third Floor

The keep contains a special level that cannot be seen from the outside: the third-floor “Dark Room” (Kuraimishige). This hidden floor explains why the interior has six levels despite a five-story exterior.

With almost no windows, the space remains dim even by day. It likely served to hide soldiers or store arms and provisions during wartime. Stepping inside today conveys an authentic sense of Sengoku-era tension.

Although the exterior resembles the layered, orderly Sōtō style, the structure is actually classified as Bōrō style, featuring a smaller watchtower set atop the upper levels. The hidden Dark Room is emblematic of this architectural distinctiveness.

A Matsumoto Specialty — Some of Japan’s Steepest Stairs

Seven stairways connect the first through sixth floors, each with a steep pitch of 55–61 degrees.

The staircase between the fourth and fifth floors is the toughest, with risers of about 40 cm. Many visitors carefully climb one step at a time—an iconic scene unique to this castle.

These steep stairs were designed to hinder attackers and now make the visit memorable. The sense of achievement after the climb is part of the experience.

Ready to Repel Invaders — Defensive Devices from the Sengoku Period

The keep retains many defensive devices typical of Sengoku castles. There are 110 arrow slits and gun ports in the walls and windows, allowing defenders to strike enemies approaching from outside.

Upper levels feature “ishiotoshi” openings for dropping stones or boiling liquids on enemies directly below. Despite the elegant exterior, the interior was built for real battle.

Narrow passages called “musha-bashiri” further constrained intruders. These authentic features tell us Matsumoto Castle was a true fortress of war.

See the Real Thing — Exhibits of Matchlock Guns and Armor

On the second floor, the “Gun Storehouse” displays numerous matchlock guns and weapons. You can compare firearms of varying calibers and lengths, a large 16 kg hand cannon, and compact self-defense pistols.

Exhibits explain how matchlocks were used, and include a large painting of the Battle of Nagashino, bringing the castle’s history vividly to life.

Seeing authentic matchlocks and armor up close is a major draw of visiting Matsumoto Castle.

Panoramic Views from the Top — Northern Alps and Castle Town

From the sixth-floor observation space, you can take in Matsumoto’s castle town and distant mountains in all directions. On clear days, the Northern Alps appear in crisp detail, pairing grand scenery with the historic keep.

Unlike some keeps with exterior galleries, Matsumoto Castle has no projecting balcony; views are taken from the windows. This practical design reflects the authenticity of an original surviving keep.

The top-floor panorama is a must for every visitor.

War Meets Peace — Edo-Era Turrets of a Connected-Compound Keep

Matsumoto Castle’s connected-compound keep links the main and smaller keeps with turrets and corridors. Notable among them are the Edo-period additions: the Moon-Viewing Turret and the Tatsumi Turret, which mark a shift from warfare to culture.

The Moon-Viewing Turret was designed for elegant moonlit banquets, featuring vermilion railings and a ship-bottom ceiling.

The Tatsumi Turret adopts temple-style katōmado (arched windows), reflecting Edo aesthetics focused on beauty rather than defense.

The contrast between the battle-ready Sengoku keep and the graceful Edo turrets tells the story of changing times at Matsumoto Castle.

History of Matsumoto Castle

Matsumoto Castle began as Fukashi Castle, said to have been built in 1504 during the Sengoku period. Amid struggles between the Takeda and Ogasawara clans, a flatland base was needed. Later, when Toyotomi retainer Ishikawa Kazumasa governed the area, large-scale improvements were made and the keep was built—the one that remains today.

In the Edo period, the Moon-Viewing and Tatsumi Turrets were added in preparation for a potential visit by the third shogun, Tokugawa Iemitsu. Although the visit never occurred, these elegant turrets remain as symbols of peace.

After the Meiji Restoration, the castle faced deterioration and proposals for demolition. Local citizens rallied to save it, raising funds and preserving the keep—thanks to which it survives today.

From Sengoku fortress to Edo cultural stage, and finally protected by townspeople, Matsumoto Castle’s journey explains why it is treasured as a National Treasure.
