Guide
The Sakamoto Castle Ruins are located in Shimohakamoto, Otsu City, Shiga Prefecture. This site once held a magnificent fortress that was said to rival the scale and splendor of the famous Azuchi Castle. Today, the area has been developed into a castle ruins park. While the surrounding area is now part of a residential district, the site remains a crucial location for understanding the layout and structural history of ancient Japanese fortifications. Built at a strategic transport hub facing Lake Biwa, this castle played a vital role in both political and military history.
Legend has it that Sakamoto Castle was constructed by Akechi Mitsuhide under the orders of Oda Nobunaga. It served as a critical stronghold to monitor Mount Hiei and to protect the 'Imadogoe' route, a vital passage to Kyoto. Historical records describe a grand structure featuring a massive main keep and a smaller secondary keep; the famous Portuguese missionary Luis Frois even once praised it as the second most magnificent castle in Japan after Azuchi. However, following the Honno-ji Incident, the castle fell and its role as a fortification ended. During the Edo period, the site transitioned into farmland and residential areas, but it remains a significant subject of historical research today.
While the original primary buildings no longer exist, the park preserves several elements that allow visitors to feel the presence of the past. You can find diagrams, historical documents, and stone monuments illustrating the original castle layout (nawari), providing a visual way to understand the former structure. The surrounding topography and river flows also serve as clues to how the castle utilized the natural environment for defense. Depending on the time of year, the changing landscape offers different perspectives on how the terrain has evolved over centuries.
Sakamoto Castle Ruins Park is an open area accessible 24 hours a day, making it an ideal spot for a casual stroll at any time. The surrounding vegetation and scenery change with the seasons, offering a refreshing walk throughout the year. For history enthusiasts, spending time observing the terrain in a quiet, contemplative environment is a truly rewarding experience. Daytime is the best time for visits, as the bright light makes it much easier to observe the topographical features and understand the historical layout.
The primary activity here is a historical walking tour. By using the provided reconstruction diagrams and maps, you can walk the grounds while visualizing the locations of the former inner bailey (honmaru), secondary bailey (ninomaru), and water gates. The surrounding area is also rich with local temples and legends related to former lords, allowing for a deep, context-rich walking tour through the history of the region.
The area around the ruins is dotted with sites of great historical value. For example, nearby temples like Tosen-ji house monuments related to significant historical figures. You can also incorporate visits to famous shrines like Hiyoshi Taisha into your itinerary. While the area is now a residential and urban district, it retains much of its historical atmosphere, serving as an excellent base for exploring the deep history of Otsu City.
