Get a glimpse into Japan's warrior past and enjoy the breathtaking beauty of nature throughout the year.

Located on the former grounds of the Satomi clan's fortress, Shiroyama Park wraps around the base of Tateyama Castle, which commands panoramic views of both the southern Boso Peninsula and the Miura Peninsula. The three-story castle, built in 1982, houses the unique Hakkenden Museum, dedicated to a 106-installment epic novel series that romanticizes the Satomi warriors' legendary exploits. This colorful saga, written by Kyokutei Bakin, is considered the longest-running novel series in Japanese history and could even be considered an early predecessor to modern manga and anime.

Beyond the castle, Shiroyama Park delights throughout the seasons. Famous across Chiba for cherry blossoms in early spring, the park is also home to camellias, plums, and azaleas, all blossoming at different times of the year. At the base, a cozy café and grassy field welcome visitors. There are two paths leading from the base of the hill to the summit, and both connect directly to the castle. From the top, visitors can enjoy views of the city and Kagami-ga-Ura, a calm, mirror-like bay known for its beautiful clarity. On clear days, Mount Fuji can also be seen on the horizon. In the park, visitors will find a traditional Japanese garden and a small museum, with access to the castle available as well. The tea house hosts traditional tea gatherings several times a year.
