Ueda Castle is a flatland castle (hirajiro) originally constructed by Sanada Masayuki in 1583. Located in the center of the Ueda Basin, it is famously known as the 'unconquerable castle' for its role in successfully repelling the massive armies of the Tokugawa clan during the first and second battles of Ueda. Today, the castle ruins have been developed into a scenic park, serving as a peaceful retreat for locals and tourists alike. Visitors can experience the atmosphere of the Sengoku (Warring States) period by exploring the stone walls, earthen ramparts, and the beautifully reconstructed watchtowers and gates.
While the Sanada clan's direct rule lasted approximately 40 years, the site remained a crucial stronghold for their influence. The castle is a major subject in Japanese novels and period dramas, drawing huge interest from history enthusiasts. Although the structures were once destroyed following the Battle of Sekigahara, the site was rebuilt and maintained by the Sen own and Matsudaira clans. Key historical features include the West Watchtower (a Prefectural Treasure from the Edo period) and the reconstructed towers and gates that allow modern visitors to visualize the castle's former grandeur.

The park grounds are filled with diverse historical sites. Essential stops include the Higashi-koguchi Gate, the Ueda City Museum, and the Ueda Castle Watchtowers (North, South, and Central). Another significant site is Sanada Shrine, a place of worship for success and victory, which deeply connects visitors to the spirit of the Sanada clan. The well-preserved stone walls and earthen embankments provide a clear visual understanding of traditional Japanese fortification structures.
Ueda Castle offers a different charm in every season. It is most famous for the 'Ueda Castle Senbonzakura Festival' in spring, when approximately 1,000 cherry trees bloom across the park. The night-time illuminations during this period create a magical, dreamlike atmosphere. Visitors can also enjoy the lush greenery of early summer, the vibrant autumn foliage, and the serene, quiet atmosphere of winter. While the park grounds are open 24 hours a day, it is best to visit during daylight hours to explore the museum and watchtowers.

Beyond sightseeing, visitors can engage in seasonal activities. For example, during the spring festival, 'Ninja Experience' programs are sometimes held at the Sanada Ninja Training Ground. Exploring the surrounding area, such as the nearby Yanagimachi district, is another excellent way to enjoy the local culture. You can walk through historic streets while learning about the regional history and enjoying local delicacies.
The castle serves as a perfect starting point for a historical walking tour. The nearby 'Yanagimachi' area retains the charming atmosphere of the old Hokkoku Kaido highway, offering beautiful traditional streetscapes and delicious local food. With many other seasonal flower-viewing spots in Ueda city, the castle is a central hub for a deep dive into Japanese history and culture.

As the grounds are quite extensive, we highly recommend wearing comfortable walking shoes. Please check the operating hours before visiting the museum or watchtowers. To preserve these precious historical remains, please respect all signs and avoid climbing on stone walls or entering restricted areas. For facility entrance fees (museum/towers), both cash and credit cards are generally accepted. While some English signage and exhibits are available, preparing basic historical context in advance will enhance your experience.
