What remains at Futamata Castle Ruins today?

The site features impressive stone walls, earthwork fortifications, moats, and the foundation of the main keep displaying nozurazumi stonework. The Honmaru (main bailey) has become a square area with remaining stone walls, and visitors can see the Asahigaoka Shrine located in the Kitakuruwa (northern enclosure). One of the most interesting aspects is how you can observe the transition from a medieval earthwork castle to a more modern stone-walled fortress, with defensive features including large tatebori (vertical trenches) and horikiri trenches cut through bedrock. However, no original buildings survive on the site.

Is there an admission fee to visit Futamata Castle Ruins?

No, admission to Futamata Castle Ruins is completely free. The site is open year-round for visitors to explore at their own pace. Facilities at the site include parking and restrooms.

What is the best season to visit Futamata Castle Ruins?

Autumn is particularly recommended for visiting, as the Honmaru area and surrounding flower gardens display beautiful autumn colors with maple trees. The combination of historic stone walls against the backdrop of colorful foliage creates an especially scenic atmosphere. Spring and early summer are also pleasant times to visit with comfortable temperatures for exploring the hilltop ruins.

How long should I plan to spend at the castle ruins?

The recommended visiting time is 1-2 hours, which allows sufficient time to explore the main bailey, stone walls, earthwork defenses, and the shrine area. Many visitors combine their trip with nearby Tobayama Castle ruins, which can be reached by walking across the embankment along the river, allowing you to visit both sites in a half-day excursion.

Can I visit other castles nearby on the same day?

Yes, Futamata Castle pairs well with Tobayama Castle, which is located on an adjacent hill separated by the Futamata River and was originally built as a siege base against Futamata Castle. With good timing, you can visit all three major castle sites in the area—Futamata Castle, Tobayama Castle, and Hamamatsu Castle—in one day by using the local train lines, starting from Futamata Honmachi Station and ending at Nishikajima Station.

Futamata Castle Ruins stands on a strategic hilltop at the confluence of the Tenryū River and Futamata River in Tenryū-ku, Hamamatsu, Shizuoka Prefecture. Originally built in 1503 by the Imagawa clan, this fortress became a critical battleground during Japan's turbulent Sengoku period. The site earned recognition as a National Historic Site in 2018 together with the adjacent Tobayama Castle.

The castle witnessed numerous conflicts between the powerful Imagawa, Takeda, and Tokugawa clans throughout the 16th century. In October 1572, Takeda Shingen captured the castle after a month-long siege in which his forces destroyed the garrison's water supply system by sending rafts down the Tenryū River to smash the water-scooping tower. The fortress finally returned to Tokugawa control in 1575 after a six-month siege. The castle holds particular historical significance as the place where Tokugawa Ieyasu's eldest son and heir, Matsudaira Nobuyasu, was ordered to commit seppuku in 1579 on suspicion of conspiracy with the Takeda clan. The castle was abandoned in 1600 after its commander was transferred to another province.

Today, visitors can explore the well-preserved stone walls and earthwork fortifications that showcase the castle's evolution from a medieval structure to a more modern fortress. The main attraction is the Honmaru (main bailey) site, which features remaining stone walls and offers views of autumn foliage. The ruins include earthworks, moats, and the Asahigaoka Shrine located in the Kitakuruwa northern enclosure. The site displays impressive nozurazumi stonework including the main keep foundation, and visitors can observe how earthwork defenses were upgraded with stone walls during later renovations.

The castle is accessible from Tenryu Futamata Station on the Tenryu Hamanako Line, approximately 10 minutes walk northeast from the station. Visitors traveling from Hamamatsu should take the Enshu Line to Nishikajima Station (22 minutes), then transfer to the Tenryu Hamanako Line. The site includes parking facilities and restrooms. Admission to the ruins is free and the site is open year-round. The recommended visiting time is 1-2 hours.

This castle was the scene of a battle between Takeda and Tokugawa. The stone walls of the main castle tower base that remain today were built after the Tokugawa side seized the castle from the Takeda. Like Hamamatsu Castle, the rugged, rough-faced limestone and chert gneiss are an irresistible treat for stone wall enthusiasts. Although the castle is compact in size, it is well-defended, with the great Tenryu River to the west and steep cliffs to the east. Currently, you can drive up to just below the Ninomaru, and there is a gentle walking path, making it an easy castle to tour. I think it would be more interesting from both a historical and geographical perspective if the trees were cut back a bit more to allow a panoramic view in the direction of Hamamatsu.
