Subtitle: Himeji Castle, Matsumoto Castle, Inuyama Castle—Which Are True Edo-Era Remnants and Which Were Rebuilt After WWII
Japan's 12 remaining wooden tenshu towers conceal a perplexing question: Amid wartime destruction and era of change, which castles have preserved their authentic historical character? This seemingly simple question reveals complex tensions between Japanese cultural conservation, tourism economy, and historical authenticity.
Tenshu History: Military and Political Symbol of the Feudal System
Tenshu were not merely military structures but political symbols created by Oda Nobunaga in the 16th century. The construction of Azuchi Castle's tenshu broke with traditional mountain castle defense logic, deliberately situating the castle on flatland to showcase the lord's power and wealth. This design philosophy reached its peak after Toyotomi Hideyoshi unified Japan—Osaka Castle's tenshu stood 58 meters tall, becoming the world's tallest wooden structure at the time.
After the Tokugawa shogunate established the "one domain, one castle" policy, restricting each domain to only one castle, the military value of tenshu rapidly declined. After the 1657 Meireki Fire destroyed Edo Castle's tenshu, the shogunate decided not to rebuild it, symbolizing the end of the tenshu era. By the Meiji Restoration, there were approximately 170 tenshu nationwide, but the abolition of domains and 1873 castle demolition orders left most castles facing demolition.
Ironically, what truly protected these castles was not government policy but local financial hardship—many domain offices couldn't afford demolition costs, accidentally allowing some tenshu to survive to this day.
12 Remaining Wooden Tenshu: Geographic Distribution and Preservation Status
Currently only 12 wooden tenshu remain in Japan, with 4 designated as National Treasures and 8 as Important Cultural Properties, showing a clear "west high, east low" geographic distribution. The Kansai region preserves 6, while the Kanto region has only 1, reflecting historical factors of wartime era political centers and WWII bombing routes.
4 National Treasures:
- Himeji Castle (Hyogo Prefecture, built 1601)
- Matsumoto Castle (Nagano Prefecture, built 1593)
- Hikone Castle (Shiga Prefecture, built 1622)
- Inuyama Castle (Aichi Prefecture, built 1537)
8 Important Cultural Properties:
These tenshu vary greatly in preservation condition. Himeji Castle underwent "Heisei-era major repairs" from 2009-2015, appearing nearly brand new; Matsumoto Castle maintains its original weathered state with naturally silver-gray wood surfaces. Different preservation philosophies directly affect visitor perception and academic value.
Himeji Castle: World Heritage Restoration Controversy
Himeji Castle became Japan's first World Cultural Heritage site in 1993, but intense controversy erupted after the 2015 completion of "Heisei-era major repairs." The 2.8 billion yen restoration project repainted the tenshu exterior snow-white, restoring its 400-year-old original state. Supporters call this "authentic restoration," while critics question it destroys the historically-layered patina of time.
The controversy's core lies in two philosophies of cultural heritage preservation: Should we preserve the "truth of time" (patina) or restore the "truth of construction" (original authenticity)? UNESCO's Nara Document supports the latter, noting that Asian wooden building traditions inherently include periodic renewal. But many visitors complain Himeji Castle has lost its ancient沧桑sense, looking like a "Disneyland replica."
Data shows the economic impact: Pre-restoration, Himeji Castle had approximately 800,000 annual visitors; post-restoration it surged to 2.87 million (2015), then quickly declined to around 1.5 million. Visitor satisfaction surveys show foreign visitors more accepting of the restored appearance, while domestic visitors generally prefer the "old look."
Matsumoto Castle: Military Design Logic of the Black Tenshu
Matsumoto Castle is the oldest surviving five-story tenshu, its deep black exterior stemming from practical military rather than aesthetic choices. Black pine resin paint is not only water-resistant and anti-corrosive but more importantly reduces the visual target for enemy forces—in the warring states era, bright white castle walls essentially signaled "please aim here."
Matsumoto Castle's architectural design reflects military practicality at every turn. The first floor's "musha hashiri" (warrior corridor) is designed with irregular routes, forcing invaders to expose themselves to multiple firing angles; stair incline reaches 61 degrees, far exceeding modern building standards of 40 degrees, making rapid siege difficult; window placement appears random but actually ensures every angle has musket firing positions.
Unlike Himeji Castle's political symbolism, Matsumoto Castle reflects "actual combat thinking." This difference also appears in preservation strategy: The Matsumoto city government deliberately maintains the building's original state, the natural silver-gray weathering of wood being viewed as "historical testimony." Visitor surveys show Matsumoto Castle's "antique charm" rating (8.7/10) significantly higher than restored Himeji Castle (6.2/10).
Inuyama Castle vs. Hikone Castle: Private vs. Public Preservation Models
The contrast between Inuyama Castle and Hikone Castle reveals institutional contradictions in Japanese cultural property protection. Inuyama Castle remained privately owned by the Naruse family until 2004, Japan's only privately-owned National Treasure castle; Hikone Castle has been public property since the Meiji era, managed by the government.
Private ownership of Inuyama Castle shows distinct "family guardian" characteristics. The Naruse family maintained it at their own expense for 450 years, developing a unique preservation philosophy: "minimal intervention, maintain original state." The castle interior preserves numerous family artifacts, including Edo-era weapons, paintings, and daily implements, providing other castles lack—the "living historical setting."
Public ownership of Hikone Castle adopts "standardized management." The government invests substantial funds for scientific conservation, establishing complete temperature-humidity control systems, fire safety facilities, and visitor flow planning. But this "museum-style management" also eliminates the building's living atmosphere—visitors can only follow fixed routes, unable to deeply understand the castle's daily use.
Operating data reflects differences between the two models: Hikone Castle has approximately 1 million annual visitors with stable ticket revenue; Inuyama Castle has only 500,000 annual visitors, but visitors stay longer (average 95 minutes vs. 65 minutes), with higher creative merchandise sales. Private ownership provides more personalized cultural experience, while public ownership ensures broader cultural普及.
Post-War Reconstructed Tenshu: Concrete Replicas in Nagoya and Osaka
After WWII, Japan reconstructed approximately 40 tenshu, but most use reinforced concrete structure, sparking intense debate over "authentic vs. fake tenshu." Nagoya Castle and Osaka Castle represent the most controversial cases.
Nagoya Castle's issues are most complex. The original tenshu was a masterpiece ordered by Tokugawa Ieyasu, destroyed in 1945 US air raids. The 1959 reconstructed concrete tenshu faithfully reproduces the exterior, but the interior is completely modernized—with elevators, air conditioning, and modern exhibition facilities. Nagoya city government recently promoted "wooden reconstruction plan," with budget reaching 50.5 billion yen, but faces triple barriers of technology, regulations, and funding.
Osaka Castle's situation is even more absurd. The existing concrete tenshu was built in 1931, predating the war, but the exterior design mixes characteristics from different eras—the base is Toyotomi-era stone walls, while the upper structure uses Tokogawa-era style. This "temporal dislocation" design makes historians shake their heads, but has unexpectedly become a tourism selling point.
Statistics show concrete tenshu tourism advantages: Osaka Castle has 2.55 million annual visitors, far exceeding any wooden tenshu. Concrete structure provides convenience impossible with wooden buildings—large exhibition spaces, barrier-free facilities, modern safety standards. But whether this convenience is worth sacrificing historical authenticity, Japanese society has yet to reach consensus.

Best Visiting Season Analysis
Spring (March-May) is traditional peak season, but crowds are daunting. During Himeji Castle's cherry blossom season, wait times can exceed 3 hours. Recommended: weekday 8:30 opening, or after 4 PM "backlight time."
Fall (October-November) provides optimal photography conditions. Matsumoto Castle's autumn foliage reflections, Hikone Castle's maple background are classic compositions. Professional photographers recommend mid-November early morning 6-7 AM, when light is soft and visitors are scarce.
Winter is an underestimated visiting season. Castles in snow have unique charm, especially Matsumoto Castle's "snow makeup" and Inuyama Castle's snow-viewing lanterns. Visitor numbers drop 70%, uninterrupted for photography—it's a secret season for photography enthusiasts.
Photography Tips
The biggest challenge in photographing tenshu is "power lines and modern buildings." Himeji Castle can be shot from Nishimaru Garden for power line-free angles; Matsumoto Castle's best photography spot is Umebashi Bridge, capturing water reflections; Inuyama Castle is recommended from the opposite bank of the Kiso River, avoiding visitor crowds.
Professional advice: Use telephoto lenses (85-200mm) to compress background, highlighting tenshu's grandeur; avoid wide-angle lens distortion; cleverly use wooden structural elements inside the castle as foreground frames, adding depth to photos.
Frequently Asked Questions (FAQ)
Q1: Among the 12 remaining tenshu, which are genuine Edo-era original structures?
A: Strictly speaking, all surviving tenshu have undergone varying degrees of restoration and renewal. Inuyama Castle preserves the most original components (approximately 70%), followed by Matsumoto Castle (approximately 60%). Although Himeji Castle's structure is original, the exterior has been completely renewed. What needs understanding is that Japanese wooden architecture tradition inherently includes periodic renewal—"originality" definition differs from Western stone construction.
Q2: Why do post-war reconstructed castles use concrete instead of wood?
A: Main reasons are cost and regulations. In the 1950s, Japan lacked technical expertise and quality timber for large wooden structures; concrete cost was only 1/3 of wood. Simultaneously, building standards law has strict limitations on tall wooden structures; concrete is easier to obtain permits for. Tourism convenience is also a factor—concrete buildings can accommodate elevators and modern facilities.
Q3: Do tenshu require advance booking? How to avoid crowds?
A: Only Himeji Castle requires online booking during cherry blossom season (early April). Other castles offer same-day tickets. Best crowd-avoidance strategies: weekday 8:30 opening, winter visit (November-February), rainy day visits. Matsumoto Castle on Tuesdays, Hikone Castle on Mondays have relatively fewer visitors.
Q4: Can photography inside castles be done? Any restrictions?
A: All castles allow interior photography, but flash and tripods are prohibited. Matsumoto Castle's Tsukimi Yagura and Himeji Castle's Daitenshu top floor are best shooting spots. Recommend wide-angle lenses (24-35mm) for interior structure, use high ISO settings for low-light environments.
Q5: Which castle is most worth in-depth visiting? How to plan routes?
A: Those interested in architectural history should choose Matsumoto Castle, preserving the most complete military design logic; those interested in cultural experience should choose Inuyama Castle, experiencing true "lord's life"; those interested in photography should choose Himeji Castle, offering the most diverse composition angles. Recommend 2-3 hours per castle, including surrounding gardens and museums.
Q6: How do tenshu differ from other types of Japanese castles?
A: Tenshu are the core structure of castles, but many important castles have no tenshu. Kumamoto Castle and Nijo Castle focus mainly on palace buildings; Shuri Castle belongs to the Ryukyu royal architecture system. Tenshu are primarily distributed in central Honshu, reflecting wartime era military needs. The 12 surviving represent the highest level of Japanese castle architecture, but do not equal the full scope of Japanese castle culture.
