A Park in the Heart of Anan
The park occupies an area known locally as Shiroyama, in Tonomachi, Tomioka-cho, the central district of Anan City. The former castle grounds were developed into a public park in 1970. In 1998, an industrial exhibition facility was built here; today, it is open to the public as Ushiki Castle Ruins Museum, known in Japanese as Ushiki Jōshikan.
Visitors can explore the green park during the day, learn about the area’s castle history, and return after sunset to enjoy the illuminations. This contrast between historical remains and contemporary light displays gives the park its distinctive character.
The History of Ushiki Castle
From a Medieval Stronghold to a Public Park
The exact date when Ushiki Castle was built is unknown, but one widely accepted theory attributes its construction to Shingai Saneshige during the Shitoku era, from 1384 to 1386. The castle occupied a strategic position in Awa Province and played a role in the region’s turbulent medieval history.
In 1582, Shingai Sanetsuna was reportedly killed by Chosokabe Motochika, after which the castle came under the control of the Chosokabe clan. In 1585, Hachisuka Iemasa took control of Awa Province, and Kashima Mondo Masayoshi entered the castle as its deputy lord.
The castle was abandoned in 1638 following the shogunate’s one-castle-per-domain policy. Although little of the original structure remains, the site has been preserved as a public park where visitors can learn about the area’s past.
Other Names: Tomioka Castle and Ukigame Castle
Ushiki Castle was also known as Tomioka Castle and Ukigame Castle. The name Tomioka became associated with the site after Kashima Mondo Masayoshi, who served as the castle’s deputy lord, renamed the surrounding area Tomioka. The castle subsequently became known by the same name.
Remaining Traces of the Castle
The original castle stood on a hill surrounded by moats, wetlands, and deep waterways that provided natural defenses. Road construction in 1913 divided the hill from north to south, leaving only a small portion of the former castle grounds intact.
An octagonal observation room now stands near the top of the southern section of the hill. Archaeological excavations have also uncovered stone walls built using the nozurazumi technique, in which naturally shaped stones are stacked without extensive cutting. Similar masonry can be seen at Tokushima Castle, offering a glimpse of the construction methods used in the region’s historic fortifications.
Highlights of the Park
Ushiki Castle Ruins Museum
The Ushiki Castle Ruins Museum, formerly an industrial exhibition facility, introduces visitors to the history of the castle and its surrounding area. Displays include historical materials and a section of the stone walls discovered during archaeological investigations.
The stonework is especially interesting for visitors with an interest in Japanese castles, as its construction technique is also associated with Tokushima Castle. Although the surviving remains are limited, they help convey the character of this former stronghold.
Kirakira Dome: A Spectacular Display of Lights
The park’s signature attraction is Kirakira Dome, an illuminated structure that glows after dark. The lights create a dreamlike atmosphere throughout the park, making the site particularly popular for evening visits and romantic walks.
Illuminations are presented throughout the year, with decorations and themes changing according to the season. The displays offer opportunities for photography and create an inviting setting for couples, families, and other visitors.
Lovers’ Sanctuary Monument
A monument marking the park’s designation as a Lovers’ Sanctuary serves as a symbolic meeting place for couples. Visitors often take photographs here against the backdrop of the nighttime illuminations, making it one of the park’s most recognizable features.
The combination of historic surroundings, illuminated scenery, and the monument’s romantic theme makes Ushiki Castle Ruins Park an appealing stop for couples exploring Anan.
Seasonal Events
Summer Festival in July
The park hosts seasonal events, including a popular summer festival in July. One of its main attractions is the collaboration between Awa Odori, Tokushima’s famous traditional dance, and illuminated objects decorated with hundreds of thousands of LED lights. The lively combination of dance, music, and colorful displays creates a festive atmosphere for visitors of all ages.
Christmas Illuminations in December
In December, a Christmas tree decorated with LED lights becomes the centerpiece of seasonal celebrations. Various activities are held around the tree, adding a festive touch to the park during the winter season.
Event dates, programs, and illumination displays may vary from year to year, so visitors planning a trip around a particular event should check the latest local announcements.
