Togane Castle is the site of a former Japanese castle in the Togane district of Togane City, Chiba Prefecture. Also known as Tokigane Castle, the site has been designated as a historic site by Togane City.
The castle is traditionally said to have been built by Sakai Sadataka during the Warring States period. Today, visitors can explore the remains of the castle and imagine the history of the samurai clans who once controlled the region.
Togane Castle is traditionally believed to have been built by Sakai Sadataka in 1521. There is also a theory that it originated from Tokigamine Castle, which was built by the Chiba clan. However, the theory that the castle was constructed by the Sakai clan is generally regarded as the more likely explanation.
The castle primarily served as the residence of the Kazusa Sakai clan. In 1590, during Toyotomi Hideyoshi’s campaign against the Hojo clan in the Siege of Odawara, the Sakai clan sided with the Hojo. After the Hojo defeat, the castle was taken over by Asano Nagamasa.
Following the abolition of the castle in 1590, Tokugawa Ieyasu was transferred to the Kanto region. Togane was subsequently developed as one of Ieyasu’s favorite locations for falconry.
In 1613, the Togane Palace was built as accommodation for Ieyasu during his visits to the area. The surrounding landscape was also developed to provide suitable grounds for his falconry activities.
Falconry at Togane came to an end after Ieyasu’s last recorded visit in 1630. The Togane Palace itself was eventually demolished in 1671.
The former site of Togane Palace is now occupied by Chiba Prefectural Togane High School. The approach to the castle ruins begins between the high school and Honzenji Temple.
The castle’s main enclosure stands at an elevation of approximately 74 meters. The remains include three enclosures to the east and two to the west. The main area covers approximately 1,000 square meters.
Although only traces of the original castle remain, the elevated location and surviving landscape features provide a glimpse into the defensive structure of a Sengoku-period castle.
Hakkaku Lake is an artificial lake located in Togane City. It originated as a pond known as Goten-ike, which was created when Tokugawa Ieyasu constructed Togane Palace. The pond was developed to improve the views from the palace.
Hakkaku Lake is also known by the poetic name “Shōseiko,” or “Little West Lake.” The combination of the tranquil lake, surrounding hills, historic buildings, and seasonal flowers makes it one of Togane’s scenic highlights.
Approximately 300 cherry trees are planted around the lake. In spring, the area becomes a popular cherry blossom viewing destination, and the annual Togane Cherry Blossom Festival attracts many visitors.
Hakkakutei, formerly known as Hakkakukan, is also located beside the lake. This historic inn was founded during the Meiji period and was visited by notable literary figures such as Kitahara Hakushu and Itō Sachio.
Part of the historic inn complex has been designated as a Nationally Registered Tangible Cultural Property.
Hakkaku Lake covers approximately 3.4 hectares and has a circumference of about 800 meters.
In addition to cherry blossoms, visitors can enjoy azaleas, Japanese irises, hydrangeas, and other seasonal flowers around the lakeshore. Each season offers a different view of the landscape.
In early April, when the cherry blossoms are at their best, the lakeside becomes especially lively with visitors enjoying hanami, or traditional cherry blossom viewing. The trees are also illuminated at night, creating an atmospheric scene along the water.
Hakkaku Lake is traditionally said to have been developed in 1614, when Tokugawa Ieyasu ordered Doi Toshikatsu to enlarge the existing pond.
The pond was originally known as Taniike or Goten-ike. Toward the end of the Edo period, the poet Toyama Unjo gave it the name “Hakkaku.” The name eventually became established as Hakkaku Lake.
During the cherry blossom season, the Togane Cherry Blossom Festival is held around Hakkaku Lake.
The festival features a variety of events, including fireworks, cherry blossom tea ceremonies, and photography sessions. Large numbers of visitors gather along the lakeshore to enjoy the spring scenery.
The illuminated cherry trees are particularly attractive after sunset, when the lakeside takes on a magical atmosphere.
From late August to early September, the Hakkaku Lake Boat Cup is held on the lake. The event adds a lively sporting element to the otherwise peaceful lakeside setting.
Sanno-dai Park is located on elevated ground to the northeast of Hakkaku Lake. During the daytime, visitors can enjoy expansive views toward the Kujukuri coast.
The park is also a popular location for enjoying the nighttime scenery. Around New Year’s Day, it attracts visitors who come to watch the first sunrise of the year.
Hakkakutei, formerly known as Hakkakukan, is a historic inn beside Hakkaku Lake with a history dating back to the Meiji period.
The inn was visited by prominent literary figures including Kitahara Hakushu and Itō Sachio. Several buildings dating from the Taisho period to the early Showa period have survived.
Five buildings—the main building, new building, accommodation building, bathhouse, and billiard hall—are designated as Nationally Registered Tangible Cultural Properties.
The former site of Togane Palace is now home to Chiba Prefectural Togane High School, a traditional school with more than a century of history.
The school also has a long history as an institution for girls and has played an important role in local education.
The area is approximately a 10-minute walk from JR Togane Station.
Local buses operated by Chiba Flower Bus, as well as highway bus services, also provide access from areas including Tokyo Station and Chiba Station.
From the Togane Interchange on the Ken-O Expressway or the Chiba-Togane Road, the area can be reached via National Route 126. The distance from the interchange is approximately 5 kilometers.
Free parking is available in the area, making it convenient for visitors traveling by car.
Togane Castle and Hakkaku Lake offer a fascinating combination of history, culture, and nature in Togane City.
The castle ruins preserve memories of the Sengoku period and the Sakai clan, while the later development of Togane as a falconry destination for Tokugawa Ieyasu adds another important chapter to the area’s history.
Nearby Hakkaku Lake grew from the pond associated with Togane Palace and has become a scenic destination known for its cherry blossoms, seasonal flowers, historic Hakkakutei, and peaceful waters.
With seasonal festivals, scenic viewpoints, and historic sites all within a relatively compact area, this part of Togane is an appealing destination for travelers interested in both Japanese history and beautiful landscapes.
