Kairyuoji Temple Five-Story Pagoda

The Temple Behind the Treasure

Kairyuoji Temple is a Shingon Risshu sect temple, founded in a location that was once part of the grand residence of Fujiwara no Fuhito, one of the most powerful statesmen of the early eighth century. After his death, the estate was inherited by his daughter, the revered Empress Komyo, consort of Emperor Shomu. Because the temple stood in the northeastern corner of the empress's palace complex, it became known affectionately as "Sumidera," meaning "the corner temple."

According to temple tradition, the temple was established in 731 through the vows of Empress Komyo, with the monk Genbo serving as its first abbot. Genbo had been sent to Tang China as a scholar-priest and returned to Japan with more than five thousand volumes of Buddhist scriptures. Legend holds that on his perilous sea voyage home, his ship was caught in a violent storm in the East China Sea. Chanting the Kairyuo-kyo sutra (Sutra of the Ocean Dragon King) with all his heart, he survived against impossible odds. The temple was named after this very sutra, and to this day Kairyuoji continues to hold ceremonies praying for safety at sea.

Why a Small Pagoda Was Built

To appreciate why this diminutive pagoda exists at all, visitors must understand the conventions of Nara-period Buddhist architecture. Major temples of the era were expected to follow a prescribed layout that included a full-sized pagoda, often towering more than 30 meters high. However, the grounds of Kairyuoji, located within the empress's private palace compound, simply did not allow for such a massive structure.

The solution devised by the temple's founders was ingenious. Rather than abandon the traditional temple layout, they constructed smaller-scale pagodas to be enshrined inside the East and West Golden Halls. In this way, the temple could maintain the formal architectural grammar of a major Buddhist complex while respecting the spatial constraints of the imperial residence. Only the West Hall's pagoda survives today, and it has been preserved continuously in its original indoor location for some thirteen centuries.

Why This Pagoda Is a National Treasure

The Kairyuoji Five-Story Small Pagoda was designated an Important Cultural Property in 1901 and elevated to National Treasure status on June 9, 1951, registered as National Treasure No. 18. The designation recognizes the structure not as a miniature craft model, but as a genuine work of architecture, the smallest such pagoda in Japan to hold this rank.

Its value rests on several exceptional qualities. Stylistically, scholars place its construction in the first half of the eighth century, with architectural details closely paralleling those of the famous East Pagoda of Yakushiji Temple. Features such as the use of ordinary rather than specialized corner brackets, the absence of diagonal support panels under the eaves, and the flat horizontal ceiling beneath the roof are all archaic elements that link the small pagoda to the very earliest phase of mature Japanese pagoda design. At the same time, certain details suggest it was built slightly later than Yakushiji's East Pagoda of around 730 but earlier than the Late Nara-period East Pagoda of Taimadera. Because so few Nara-period timber structures survive at all, the small pagoda is an irreplaceable document of how Japanese pagoda architecture evolved.

Two additional objects are jointly designated as National Treasure attachments: two scrolls of the Lotus Sutra housed in a wooden box, and two metal fittings originally used on the rafters of the pagoda itself.

Architectural Highlights to Look For

Standing at 4.01 meters including its bronze finial (2.85 meters without), the pagoda is a complete five-story structure faithful in every detail to full-scale counterparts. Because it was designed to be viewed up close indoors, the craftsmen paid extraordinary attention to visual finesse. Each successive story is subtly narrower than the one below, giving the tower a harmonious, tapering silhouette that is pleasing from any angle.

The ground floor is remarkable for having no doors or walls; all three bays on each side are left open, allowing visitors to peer into the interior structure. From the second level upward, the pagoda is encircled by handrailed walkways with central door bays (though the doors themselves are only simulated). The roof tiles, though small, are rendered in the hongawara style of authentic ceramic roof tiles using thin wooden boards shaped to resemble them.

One fascinating technical detail distinguishes this pagoda from its sister small pagoda at nearby Gangoji Temple. While Gangoji's small pagoda is constructed by assembling individual timber members piece by piece, exactly as a full-scale pagoda would be, the Kairyuoji pagoda uses a different method: box-like structures are stacked in tiers, with the finer ornamental brackets and details applied to the exterior. Despite this simplification, the visible craftsmanship from the outside is breathtakingly precise.

An inscription on the stone base dates to 1297, indicating that restoration work was performed in the Kamakura period. The current bronze finial was replaced in 1906 during the Meiji era.

Visiting Kairyuoji Temple

The small pagoda is enshrined within the Saikondo, or West Golden Hall, which is itself a designated Important Cultural Property. The hall dates back to the Nara period, though it underwent extensive restoration during the Kamakura era. Together with the small pagoda, it represents the only surviving Tenpyo-era architecture within the former palace grounds of Empress Komyo.

Kairyuoji is a small, contemplative temple, and visiting it feels very different from visiting Nara's more famous attractions. The grounds are intimate and quiet, and during late March through mid-April the compound is covered in the delicate white blossoms of yukiyanagi (thunberg spirea), for which the temple is locally famous. In spring the principal image, a Kamakura-period statue of the Eleven-Headed Kannon (also an Important Cultural Property), is put on special display. Autumn brings another special opening from late October through early November.

The temple is a short walk from Hokkeji-mae bus stop and can be combined easily with visits to neighboring Hokkeji Temple, which was once the chief nunnery of the nation under Empress Komyo's patronage.
