Bannaji Temple: A Modest Temple Marked by the Crests of Three Great Houses

Bannaji Temple

(Ashikaga City, Tochigi)

【Kamon（家紋）】 are traditional Japanese family crests that signify lineage and social status. For historically prominent clans, a single crest is enough to identify which family it belongs to. In the medieval period, crests were displayed on clothing and personal belongings to signify a family’s prestige and authority. When visiting Japanese castles, temples, and shrines, you can often find these crests on gates, roof tiles, and architectural details, revealing the families with whom the site was closely connected. Understanding kamon allows you to appreciate Japanese history and culture on a deeper level.

The city of Ashikaga in Tochigi Prefecture lies at a strategic point where the northern edge of the Kanto Plain meets the surrounding foothills. The Watarase River flows along its southern side, and in earlier times the city prospered through river transport.

At the center of this city stands Bannaji Temple, surrounded on all four sides by earthen ramparts and moats—features unusual for a Buddhist temple. These fortifications were originally constructed as part of the residence of the Ashikaga clan, a powerful samurai family who ruled this region during the turbulent medieval era. The temple was established within the residence by the Ashikaga clan in 1197. Owing to this historical background, the site was selected as one of “Japan’s Top 100 Castles,” despite its present role as a Buddhist temple.

Today, the temple no longer retains the atmosphere of a medieval stronghold. Instead, it offers a calm and peaceful setting. Carp swim gracefully through the shallow moat, and the carefully maintained pines and other trees atop the ramparts add to the beauty of the surrounding townscape.

At the center of the temple grounds stands the main hall, designated a National Treasure. Its large and imposing tiled roof bears three family crests along the roof ridge. On the left is the paulownia crest, traditionally bestowed by the emperor only upon his most trusted retainers as a mark of the highest honor. In the center is the chrysanthemum crest of the Imperial Family. On the right is the Ashikaga clan’s crest, a design of two thick lines enclosed within a circle. Together, they symbolize the close connection between the Ashikaga clan and the Imperial Household.

The Ashikaga clan’s connection to the imperial family traces back to the ninth century. The clan was a cadet branch of a warrior lineage descended from Emperor Seiwa’s sixth prince. For centuries, members of this lineage gained fame through military achievements while serving the imperial court.

One of the clan’s most significant leaders was Ashikaga Takauji, who, nearly five centuries after Emperor Seiwa, helped overthrow the former shogunate through fierce conflicts across the country in support of the then Emperor Go-Daigo. He later established the Muromachi shogunate in Kyoto in the fourteenth century. Ironically, the former shogunate had also been founded by the same imperial lineage.

As you walk around the temple grounds, you will find a mausoleum enclosed by vermilion fences in the northwestern corner. On its roof appears the Tokugawa crest—the aoi (hollyhock) emblem. The structure is said to have been rebuilt and donated by the Tokugawa family, who established the Tokugawa shogunate in the seventeenth century. Their patronage is believed to reflect a desire to associate themselves with the prestigious Ashikaga lineage, whose imperial ancestry was regarded as a mark of distinction among samurai families. The multi-storied pagoda near the center of the grounds was likewise rebuilt and donated by the Tokugawa family.

Though Bannaji may appear to be a modest former residence in a provincial city, it is a truly exceptional place where the crests of the Imperial Family and the two warrior governments that unified Japan—the Ashikaga and the Tokugawa—can all be found.
