The "Big Three": Japan's Most Iconic Castles

When discussing must-visit Japanese castles, three stand out due to their historical significance, architectural beauty, and well-preserved structures. These are often referred to as the "Big Three," and for good reason:

1. Himeji Castle (Hyogo Prefecture)

Often hailed as the most beautiful and complete feudal castle in Japan, Himeji Castle is a UNESCO World Heritage site and a National Treasure. Its brilliant white exterior, resembling a soaring egret, has earned it the nickname "White Heron Castle."

History: The current structure dates back to the early 17th century, built by Ikeda Terumasa. It survived numerous wars and earthquakes, largely due to its intricate defensive design.
Architecture: Himeji Castle boasts an incredible labyrinth of over 80 buildings and a sophisticated defensive system. Its main keep, or tenshu, is a five-story structure that is interconnected with smaller towers. The whitewashed plaster walls are not just for aesthetics; they were fireproof and designed to be a formidable defense.
What to See: Explore the winding paths and narrow passages designed to confuse and trap invaders. Climb to the top of the main keep for panoramic views of the surrounding city and countryside. The intricate wooden joinery and the sheer scale of the construction are breathtaking.
Getting There: Easily accessible by Shinkansen (bullet train) to Himeji Station.

2. Matsumoto Castle (Nagano Prefecture)

Known as the "Crow Castle" due to its black exterior, Matsumoto Castle is another of Japan's most stunning original castles. It is one of the few remaining castles with a moated complex and an intact original keep.

History: Construction began in the late 16th century. It served as a strategic stronghold for the Ishikawa and later the Tokugawa clans.
Architecture: Matsumoto Castle features a five-story main keep and a smaller three-story sub-keep, connected by a covered walkway. Its distinctive black wooden exterior is striking. The interior is steep and narrow, reflecting its defensive purpose.

Getting There: Accessible by train from major cities like Tokyo and Nagoya.

3. Osaka Castle (Osaka Prefecture)

While much of the current structure is a modern reconstruction, Osaka Castle is a symbol of Osaka's history and power. Its imposing presence and rich historical context make it an essential visit.

History: Originally built in the late 16th century by Toyotomi Hideyoshi, it was a symbol of his power. It has been destroyed and rebuilt several times throughout history, most notably by Tokugawa forces and during WWII bombings.
Architecture: The reconstructed castle is a magnificent, multi-story structure with a prominent golden motif. The outer moats and stone walls are original and impressive in their own right.
What to See: The main tower now houses a museum detailing the castle's history and Toyotomi Hideyoshi's life. The views from the top floor are spectacular. The grounds are vast and popular for picnics and viewing cherry blossoms.
Getting There: Located in the heart of Osaka, easily reachable by subway.

Other Notable Castles Worth Exploring

Beyond the "Big Three," Japan offers a wealth of other historically significant and visually stunning castles that offer unique experiences:

5. Kanazawa Castle (Ishikawa Prefecture)

Kanazawa Castle, adjacent to the famous Kenrokuen Garden, has been meticulously restored and offers a glimpse into a typical feudal lord's residence and defensive stronghold.

History: Originally built in the late 16th century, it was the seat of the powerful Maeda clan. It has suffered multiple fires throughout its history, leading to various reconstructions.
Architecture: The castle features several restored turrets, gates, and the striking Ishikawa-mon Gate. The use of traditional techniques in its reconstruction is evident.

Getting There: Accessible by Shinkansen to Kanazawa Station.

6. Kumamoto Castle (Kumamoto Prefecture)

Known for its impressive defensive walls and towers, Kumamoto Castle is a remarkable example of Japanese castle architecture, though it suffered significant damage in the 2017 Kumamoto earthquake and is undergoing extensive restoration.

Frequently Asked Questions

How many original castles are left in Japan?

While hundreds of castles once dotted the Japanese landscape, only a dozen or so are considered "original," meaning their main keeps and defensive structures have survived largely intact from the feudal era. Many others are reconstructions, but they still offer invaluable historical insights and architectural beauty.

Why are some Japanese castles black and others white?

The color of a castle's exterior was often due to the materials used in its construction and the plastering techniques. White plaster, as seen at Himeji Castle, was fireproof and helped to protect the wooden structures. Black exteriors, like at Matsumoto Castle, were often achieved through the use of dark wood and sometimes black lacquer or paint, giving them a formidable appearance.

Are the interiors of Japanese castles furnished?

Generally, the interiors of Japanese castles are not furnished in the way one might expect from a European castle. The focus is on the architectural elements, such as the wooden beams, staircases, and defensive features. Many castles now house museums that display artifacts, armor, and historical documents related to the castle and its former lords.
