Nagoya Castle,a landmark of Nagoya City in Aichi Prefecture,is renowned for its ancient significance and architectural beauty. However, a lesser-known chapter in its history reveals a surprising coexistence with a functioning railway line, affectionately dubbed the “moat train” by local residents. This unique railway operated for 65 years,from 1911 to 1976,running directly through one of the castle’s outermost moats.

A large crowd bids farewell to a departing “moat train” at the now-defunct Horikawa Station in Nagoya’s Naka Ward on February 14, 1976.

Initially constructed in 1615 under the orders of Tokugawa Ieyasu,Nagoya Castle’s moats served a crucial defensive purpose. They were designed to impede potential attackers. The utilization of the outermost moat by the Meitetsu Seto line railway in 1911 was an adaptation to the evolving transportation needs of the region and a testament to innovative infrastructure planning.
The ‘Moat Train’ and the Ceramics Trade
The “moat train” wasn’t merely a local curiosity; it played a vital role in the regional economy. The line connected Owari Seto Station to the now-closed Horikawa Station, facilitating the transportation of “Setomono,” or Seto ware ceramics, from the production center of Seto to Nagoya Port. These goods were then shipped domestically and internationally.
At Horikawa Station, strategically located approximately one kilometer southwest of the castle’s main gate, cargo was transferred from trains to boats navigating the Hori river, streamlining the distribution process. This intricate logistical network underpinned a significant portion of the region’s trade.

Nagoya Castle remains a popular tourist destination, attracting visitors from around the globe.
Shifting Infrastructure and the Line’s Demise
Following the Second World War, Japan experienced a paradigm shift in its transportation systems. The increased use of trucks gradually diminished the necessity of waterborne transport, prompting a reassessment of the “moat train’s” utility. As demand for convenient access to Nagoya’s Sakae district grew,the Seto Line was rerouted to Sakaemachi Station,leading to the discontinuation of the unique railway in 1976.
today, the railway tracks have been removed, yet the story of the “moat train” persists as a fascinating footnote in Nagoya’s history. visitors to Nagoya Castle can now contemplate the site of this unusual intersection of defense, commerce, and transportation innovation.

What were the primary factors that led too the decision to build the Inuyama Line’s embankment within Nagoya Castle’s moat instead of rerouting the railway?

The Meitetsu Inuyama Line and Nagoya Castle’s Moat
From 1911 to 1976, a unique chapter in nagoya’s history unfolded – the operation of trains directly alongside, and even through, the outermost moat of Nagoya Castle. This wasn’t a standard railway route; it was a engaging consequence of urban progress intersecting with a historic landmark. The key player was the Meitetsu Inuyama Line (名鉄犬山線), a vital transportation artery connecting Nagoya with the surrounding areas. Understanding this period requires looking at the line’s evolution and the castle’s context. Nagoya Castle, originally constructed in the early Edo Period (1603-1868) by the Owari tokugawa clan, was a notable fortress and symbol of power. By the early 20th century, the castle grounds were becoming integrated into the expanding city of Nagoya.
Origins: The Need for a Railway Connection
The impetus for the inuyama Line stemmed from the growing need to connect Nagoya with the towns of Inuyama and Meitetsu. Initial plans involved a route that unfortunately required traversing a portion of Nagoya Castle’s outermost moat. This presented a significant engineering and preservation challenge. Rather than a costly and potentially damaging rerouting, a unique solution was adopted: building a railway embankment within the dry moat.
Early 20th Century Nagoya: Rapid industrialization and population growth demanded improved transportation infrastructure.
Meitetsu’s Role: The Meitetsu (Nagoya Railroad) company was instrumental in developing the regional railway network.
Castle Preservation Concerns: Balancing modernization with the preservation of Nagoya’s historical heritage was a key consideration.
Construction and Operation (1911-1945)
Construction began in 1911, and the line opened shortly after. For decades, trains ran along an elevated embankment built within the moat. This created a striking visual – trains seemingly running alongside the castle walls. The section of the moat utilized was the outermost moat, a defensive feature that had already lost much of its original water retention capacity by this time.
Embankment Construction: The embankment was carefully engineered to minimize impact on the castle foundations.
train Operations: Regular passenger and freight services operated on this unique section of the line.
Visual Impact: Photographs from this era showcase the unusual juxtaposition of modern trains and the historic castle.
World War II Damage: Nagoya Castle suffered significant damage during the air raids of 1945,but the railway line itself remained largely functional,though subject to wartime restrictions.
Post-War Reconstruction and Continued Use (1945-1976)
Following World War II, Nagoya underwent extensive reconstruction. while the castle was rebuilt (with concrete reconstructions of the main keep and other structures), the railway line continued to operate as before. The presence of the railway became a familiar part of the Nagoya cityscape. However, the limitations of the route and the growing need for modernization prompted discussions about its future.
Castle Reconstruction: The rebuilding of Nagoya Castle provided an prospect to reassess the railway’s long-term viability.
Increased Train Traffic: Post-war economic growth led to increased demand for rail transport.
Urban planning Considerations: Changes in urban planning and traffic patterns influenced decisions regarding the railway line.
The Rerouting and Legacy (1976 Onward)
In 1976, the Meitetsu Inuyama Line was rerouted. A new, underground section was constructed, eliminating the need for the embankment within the castle moat. This allowed for the restoration of the moat to a more natural state and improved the overall aesthetic of the castle grounds. The original railway embankment was dismantled, and the moat was refilled.
Underground Construction: The new underground section of the line was a significant engineering feat.
Moat Restoration: The rerouting enabled the restoration of the moat, enhancing the castle’s historical environment.
Modernization of the Inuyama Line: The rerouting was part of a broader effort to modernize the meitetsu Inuyama Line.
Preservation of history: The decision to reroute the line ultimately prioritized the preservation of Nagoya Castle’s historical integrity.
Benefits of the rerouting
The rerouting of the Inuyama Line offered several key benefits:
Enhanced Historical Aesthetics: Removing the railway embankment significantly improved the visual appeal of Nagoya Castle.
Improved Moat Environment: Restoration of the moat created a more natural and aesthetically pleasing environment.
increased Railway Efficiency: The underground section of the line provided a more direct and efficient route.
Long-Term Preservation: The rerouting ensured the long-term preservation of Nagoya Castle as a historical landmark.
