Selected as one of Japan’s “100 Most Famous Cherry Blossom Viewing Spots” and “100 Famous Japanese Castles,” this representative park of Okazaki attracts numerous visitors throughout the year, cherished not only by history enthusiasts but also by tourists seeking to enjoy nature in all seasons.
History and Overview of Okazaki Castle Park
Historical Significance as Tokugawa Ieyasu’s Birthplace
Okazaki Castle is said to have been built in 1452 (Kyōtoku 1) by Saigō Tsuguyori and later became the residence of the Matsudaira clan. On December 26, 1542 (Tenmon 11), Tokugawa Ieyasu (then known as Matsudaira Takechiyo) was born at Okazaki Castle. Ieyasu spent his childhood at Okazaki Castle and later founded the Edo Shogunate, establishing a peaceful era lasting over 260 years, making him one of the most important figures in Japanese history.
Okazaki Castle earned the title “Most Famous Castle in the Tōkaidō” and flourished as the political and economic center of Mikawa Province. Even after Ieyasu achieved national unification, Okazaki remained important as a land connected to the Tokugawa clan, with successive castle lords being daimyo from hereditary Tokugawa vassal families.
Establishment and Development of Okazaki Castle Park
Following the Meiji Restoration, Okazaki Castle was abandoned and its structures, including the tenshu, were demolished. However, the castle grounds were developed into a park, and in 1959 (Showa 34), the tenshu was reconstructed. The current Okazaki Castle Park has been developed as a historical park centered on Okazaki Castle, with remnants such as castle walls, inner moats, and stone ramparts evoking memories of the past.
In 2023, the Okazaki Castle tenshu underwent renovation and reopened as an interactive facility utilizing the latest exhibition technology. This new Okazaki Castle Park, where history and modern technology merge, has become a place communicating the history of Ieyasu and Mikawa warriors to more people.
Main Attractions of Okazaki Castle Park
Okazaki Castle Tenshu
The Okazaki Castle tenshu, the central attraction of Okazaki Castle Park, is characterized by its beautiful white exterior. Following its renovation in 2023, the interior features enhanced exhibitions allowing visitors to experience Ieyasu’s life using the latest digital technology.
Inside the tenshu, visitors can learn about Ieyasu’s dramatic life—from his birth and childhood through the unification of Mikawa, the Battle of Sekigahara, and the opening of the Edo Shogunate—via video, dioramas, and interactive displays. From the observation room on the top floor, one can overlook Okazaki’s cityscape and the flow of the Otogawa and Igagawa rivers, imagining the landscape Ieyasu once beheld.
The stone ramparts surrounding the tenshu remain, allowing observation of various construction techniques from different eras. Visitors can study the evolution of castle architecture through coexisting stone-laying methods: nozura-zumi (rough-faced), uchikomsegi (dressed stone), and kirikomiSegi (closely fitted stone).
Mikawa Warriors Residence Ieyasu-kan
The Mikawa Warriors Residence Ieyasu-kan is a historical museum where visitors can deeply learn about Tokugawa Ieyasu and the history of Mikawa warriors. The museum displays the lives of the “Tokugawa Four Heavenly Kings”—Honda Tadakatsu, Sakakibara Yasumasa, Ii Naomasa, and Sakai Tadatsugu—who supported Ieyasu, along with the samurai spirit they embodied.
The museum features dioramas recreating the Battle of Sekigahara and exhibits actual artifacts including weapons and armor from the period, allowing visitors to experience the vividness of the Warring States era. It also provides detailed explanations of how the characteristic Mikawa warrior spirit of “honest integrity” and “loyalty” was cultivated and became the foundation of the Edo Shogunate.
Regular special and themed exhibitions are held, with visitors able to learn Okazaki’s history from multiple perspectives, including findings from excavations at the Shingū site. Exhibitions on themes such as the 50th anniversary of designation as a National Historic Site vary by season, offering new discoveries with each visit.
Ryūjō Shrine
Ryūjō Shrine, enshrined within Okazaki Castle Park, has been revered as the guardian deity of Okazaki Castle. “Ryūjō” (Dragon Castle) refers to an alternative name for Okazaki Castle, derived from a legend that when Ieyasu was born, a golden dragon appeared in the sky above the castle.
The shrine enshrines Tokugawa Ieyasu and Honda Tadakatsu, believed to grant blessings for success and advancement, warding off misfortune, and safe childbirth. Particularly during exam season, many test-takers visit to invoke Ieyasu’s spirit of “perseverance and effort.”
The grounds contain ancient sacred trees with centuries of history and various historic sites connected to Ieyasu, allowing visitors to pay respects in a serene atmosphere. Commemorative stamps (goshuin) are popular, and seasonal special stamps are sometimes issued.
The Ubuyu (Birth) Well and Ena Mound
Within Okazaki Castle Park stands the birth well, said to be where water was drawn for Ieyasu’s birth bath. This “Ubuyu” (Birth Well) is preserved as an important historic site symbolizing the location of Ieyasu’s birth.
The Ena Mound (えな塚), where Ieyasu’s placenta was buried, also remains in the park. These historic sites, commemorating Ieyasu’s birth and infancy, serve as popular destinations for history enthusiasts.
Tatsumi-kaku and Tea Rooms (Aoi-shouan and Jōnan-tei)
Okazaki Castle Park includes facilities where visitors can experience traditional Japanese culture. Tatsumi-kaku was relocated from the former residence of Honda Tadatsugu and showcases distinguished Japanese architecture.
The tea rooms Aoi-shouan and Jōnan-tei offer experiences of authentic tea ceremony. At Jōnan-tei’s standing tea counter, visitors can casually enjoy matcha, with green tea also available for purchase. Time spent quietly enjoying tea in this historical park is a luxurious moment to appreciate the depth of Japanese culture.
Noh Theater and Cultural Facilities
Maruno Noh Theater stands within Okazaki Castle Park, hosting regular performances of Noh, a traditional performing art. Watching Noh in this historic atmosphere offers a special charm.
These cultural facilities demonstrate that Okazaki Castle Park is not merely a historical tourist site but a place where visitors can comprehensively experience Japanese traditional culture.
