History of Toba Yama Castle and Its Value as a Nationally Designated Historic Site
Tokugawa Ieyasu’s Connection to Toba Yama Castle
In discussing the historical significance of Toba Yama Park, the existence of Toba Yama Castle, built during the Sengoku period, is indispensable. Historical records show that in 1575 (Tensho 3), Tokugawa Ieyasu established his headquarters on this Toba Yama when attacking Futagashi Castle, which was under Takeda clan control.
At that time, Futagashi Castle was an important stronghold of the Takeda clan. Ieyasu made strategic use of Toba Yama, this natural fortress, and surrounded Futagashi Castle. He ultimately succeeded in recapturing Futagashi Castle. This historical event has given deep historical significance to the site of present-day Toba Yama Park.
Remains of the Mountain Castle and Excavation Surveys
Recent excavation surveys have revealed that Toba Yama Castle contains many precious remains. The main structures include the following:
- Kuruwa (enclosures): Flat sections of the castle grounds, with multiple terraced kuruwa confirmed
- Koguchi (castle gates): Defensive entrances to the castle
- Masugata gate: A bent gate structure designed to prevent enemy intrusion
- Ote-do (main road): Road leading to the main castle entrance
- Dorui (earthen wall): A defensive wall made of piled earth
- Horikiri (moat cut): A moat cut through the ridge
These remains are extremely important materials for understanding the structure of Sengoku-period mountain castles, and explanatory plaques are installed throughout the park. You can enjoy a historical walk while imagining what the castle looked like at that time.
Nationally Designated Historic Site “Toba Yama Castle Ruins”
In 2018 (Heisei 30), Toba Yama Castle ruins were officially designated as a national historic site. This is testament to its highly valued academic and historical significance as a Sengoku-period mountain castle.
With the designation as a nationally designated historic site, further preservation and enhancement efforts are being advanced, strengthening initiatives to convey this historical heritage to future generations. For history enthusiasts, it is certainly a highly worthwhile spot to visit as a place connected to Tokugawa Ieyasu.
Seasonal Attractions｜Cherry Blossoms, Autumn Foliage, and Night Views
Spring Cherry Blossoms｜One of Hamamatsu’s Premier Cherry Blossom Viewing Locations
The spring cherry blossom season is when Toba Yama Park shows its most spectacular appearance. Approximately 1,000 Somei Yoshino cherry trees are planted throughout the park, and during the bloom season, the slopes from the middle of Toba Yama to its summit are painted pink in an awe-inspiring scene.
Peak Viewing Period
Late March to early April (typical years)
Ways to Enjoy the Cherry Blossoms
- Viewing from the observation deck: The contrast of cherry blossoms with the Tenryu River and Enshu Plain is spectacular
- Cherry blossom picnic at the Honmaru Plaza: Enjoy the blossoms leisurely on the lawn
- Walking the scenic paths: A walk surrounded by cherry blossoms throughout the entire mountain is exceptional
- Evening cherry blossom viewing: While there is no illumination, viewing the cherry blossoms by moonlight has its own charm
During cherry blossom season, the park is busy with local residents and tourists, but since the entire mountain is expansive, it is not overly crowded, allowing for leisurely flower viewing.
Autumn Foliage Season
As autumn arrives, Toba Yama Park is also known as a location for viewing autumn foliage. The cherry trees turn color for fall, and the broad-leaved trees such as Japanese maple display red and yellow hues—a different kind of beauty from the spring blossoms.
Peak Viewing Period
Mid-November to early December (typical years)
The autumn foliage season is relatively quiet, allowing visitors to enjoy walks in a calm atmosphere. The contrast between the Tenryu River and the autumn colors is ideal for photography.
