Bicchu Takamatsu Castle Ruins and Water Siege: Tracing Historical Remains Created by Toyotomi Hideyoshi's Strategy

The Bicchu Takamatsu Castle Ruins in Kita-ku, Okayama City, are a historic spot known as the stage of the famous water siege waged in 1582 by Toyotomi Hideyoshi, then called Hashiba Hideyoshi. This battle, in which a flatland castle built on low wetland was surrounded like a lake by water held back with embankments, is known as one of the three great water sieges of Japan, alongside Ota Castle in Kii and Oshi Castle in Musashi, and has been handed down as an event symbolizing Hideyoshi ingenuity. Today the ruins are developed as a park, a place to enjoy the romance of Sengoku history and the calm scenery of blooming lotus flowers.

Highlights

Bicchu Takamatsu Castle was a natural stronghold surrounded by marshes and deep paddies, hard to attack. Against it, Hashiba Hideyoshi, who was subjugating the Chugoku region on the orders of Oda Nobunaga, adopted an extraordinary strategy on the advice of his strategist Kuroda Kanbei (Yoshitaka): building a long embankment around the castle and using the rise of the rainy season to submerge it. The embankment, built by a rush construction, was completed in a short time, and the castle held by castellan Shimizu Muneharu was surrounded by water and isolated.

Amid the struggle over the isolated castle, news arrived that the Honnoji Incident had occurred in Kyoto and Oda Nobunaga had been killed. Hideyoshi concluded a peace on the condition of Muneharu suicide and set off on the Chugoku Osegaeshi, a forced march back to Kyoto to strike down Akechi Mitsuhide. This chain of events became a major turning point in history that would decide the fate of the realm.

Today the Bicchu Takamatsu Castle Ruins are developed as Takamatsu Castle Ruins Park, where the main enclosure site and part of the water-siege embankment remains can be recalled. In the marshland within the park, lotus flowers bloom in summer, spreading a beautiful scene of pink blossoms coloring the water surface. Nearby is a museum where the water siege can be studied more deeply.

Seasonal Enjoyment

The best season for the Bicchu Takamatsu Castle Ruins is summer (around July to August), when lotus flowers bloom across the marshland. Because lotus flowers open in the early morning, visiting in the morning lets you enjoy their fresh appearance. A moment reflecting on Sengoku history while gazing at the flowers is exceptional.

Access and Essentials

Access is very convenient, within walking distance of Bitchu-Takamatsu Station on the JR Kibi Line (Momotaro Line). From Okayama Station it is about a 20-minute train ride. Since the visit centers on touring historic sites, wear comfortable walking shoes. The park is open, but the museum has set open days and hours, so it is reassuring to check in advance.

Practical Travel Notes

The castle ruins park is flat and easy to walk, and can be toured even in a short time. The lotus season is popular, and the earlier the morning, the prettier the flowers and the fewer the crowds. Nearby historic sites of the Kibi Road, such as Kibitsu Shrine, Tsukuriyama Kofun, and Kinojo Castle, are scattered about, so touring them together makes for a rich historical walk. Public transport is infrequent, so check the timetable when planning.

A Word of Advice

Once the stage of a fierce battle, the Bicchu Takamatsu Castle Ruins have transformed into a peaceful place of flowers. Visit this historic ground, where Hideyoshi ingenuity is inscribed, in time with the lotus season.
