Kawaharadera Temple Site: The Marble Foundations of a Lost Imperial Sanctuary
Twenty-eight pale stones lie in formation on the south side of Asuka village, their surfaces marbled in soft grey and white. They are foundation stones of a vanished seventh-century temple, and they are made of actual marble. No other temple in Japan used such material for its base. The site is Kawaharadera, designated a National Historic Site in 1921, and it covers roughly 73,839 square metres of the old capital district where the Japanese state took shape.
Today only the platforms and stones remain in the open precinct, with a small successor temple called Gufuku-ji standing on the original Middle Hall foundation. The site belongs to the candidate property "Asuka-Fujiwara: Archaeological Sites of Japan's Ancient Capitals and Related Properties," currently under review for UNESCO World Heritage inscription.
A Temple Tied to Three Emperors
The founding date of Kawaharadera remains contested. Five different theories have been proposed, ranging from the reign of Emperor Bidatsu in the sixth century to the year 774 in the late eighth. The most widely repeated tradition holds that Emperor Tenji built the temple to pray for the soul of his mother, Empress Saimei, on the site of her Kawahara Palace. Archaeology has supported part of this story: excavators found earlier structural remains beneath the temple, and some scholars identify these with the palace itself.
What can be stated with confidence is that the temple existed by the early 670s. The Nihon Shoki, Japan's oldest official chronicle, records an event in the second year of Emperor Tenmu's reign (673): scribes were gathered at Kawaharadera and began the first copying of the complete Buddhist canon ever undertaken in Japan. The temple thus holds a quiet but extraordinary place in religious history as the country's first scriptorium for Buddhist texts.
Tenmu maintained an unusually close relationship with the temple. When he fell gravely ill, sutras were chanted here for his recovery. When envoys arrived from the Korean kingdom of Silla, gigaku dance performances were dispatched from Kawaharadera to entertain them. After Tenmu's death in 686, his widow Empress Jitō held a great memorial assembly at five temples, and Kawaharadera was among them.
The Kawaharadera Plan: A Layout Found Almost Nowhere Else
Systematic excavation between 1957 and 1959 revealed that Kawaharadera was built to a plan unlike any contemporary monastery in the capital region. Most major Asuka-period temples placed a single main hall on the central north-south axis, with a pagoda either in front or to one side. Kawaharadera did something stranger.
From a southern gate, a corridor extended around a rectangular precinct. The Middle Hall stood at the centre of the corridor's north side. Within the enclosed courtyard, two structures faced each other across the open ground: a five-storey pagoda to the east, and a smaller West Hall to the west. The West Hall did not face south as a Japanese main hall normally does. It faced east, turning towards the pagoda across the courtyard. Behind the Middle Hall stood a lecture hall, ringed on three sides by monks' quarters.
This arrangement, with two halls and one pagoda inside a single roofed corridor, became known as the Kawaharadera-style temple plan. Only a handful of other sites are thought to have followed it, including Minamishiga-haiji near the short-lived Ōtsu capital and Kanzeon-ji in Kyushu. Within the Asuka heartland the design is unique.
The temple's southern boundary stretched some 300 metres north to south and over 200 metres east to west, placing it among the largest religious complexes of its day, on a scale comparable to nearby Asuka-dera.
Marble, Lotus Tiles, and Clay Buddhas
The most distinctive surviving feature is the Middle Hall foundation. Each of its 28 column bases was cut from white marble, a material later temples in Japan never repeated. Temple tradition long described the stones as agate, but petrographic study has confirmed they are marble. The Middle Hall itself measured three bays across the front and two deep at its core, surrounded on all four sides by open eaves with no doors or walls between the columns, an unusually airy design for a major hall.
The roof tiles excavated at the site are equally important. They carry a pattern called fukuben renge-mon, a compound double-petal lotus design with eight petals each split into two lobes. This pattern, first developed at Kawaharadera, became the dominant template for Japanese roof tiles for the following century.
The hill behind the temple, known as the Kawaharadera Urayama site, has produced some of the most striking finds. Excavations there recovered well over a thousand senbutsu, small clay tablets pressed with images of triad Buddhas, along with several hundred fragments of unfired clay statues. Some bear traces of gold leaf. These pieces, now central to displays at the nearby Asuka Historical Museum, suggest that the interiors of the seventh-century halls were brilliantly decorated with gilded reliefs covering the walls.
Decline, Rebirth, and What Remains
Of the four state temples of Asuka, three (Asuka-dera, Daikandai-ji, and Yakushi-ji) were moved north when the court relocated to Heijō-kyō, the new capital at Nara, in 710. Kawaharadera alone stayed where it was. The reason has never been fully explained.
The temple suffered a major fire in the ninth century and was rebuilt by the Shingon monk Shōbō, who later founded Daigo-ji in Kyoto. A second fire late in the twelfth century reduced it further, and the great precinct gradually fell from prominence. The small temple of Gufuku-ji that occupies the Middle Hall site today preserves the older name as an alternate reading and continues to function as a place of practice, holding sutra-copying sessions for visitors that echo the temple's role thirteen centuries ago.
Inside Gufuku-ji are wooden standing images of Jikoku-ten and Tamon-ten, two of the Four Heavenly Kings, both registered as Important Cultural Properties. Tradition attributes them to Kūkai, although their actual date is harder to pin down. A set of Twelve Heavenly Generals from the early Heian period is also enshrined.
Walking the Site Today
The site is laid out as an open archaeological park. Visitors can walk among the platform mounds and read panels showing the original plan, then enter Gufuku-ji to see the marble foundations preserved beneath the current hall. Across the road to the south sits Tachibana-dera, said to be the birthplace of Prince Shōtoku, and the famous Ishibutai burial mound lies a short walk to the east. To the north, the small Asuka Historical Museum displays many of the senbutsu and tiles recovered from the precinct.
The flat fields around the site once held the residences and offices of the Asuka court. Walking the lanes between rice paddies, with the gentle outline of Mount Amanokagu visible to the north, gives a clearer sense of the seventh-century landscape than almost anywhere else in Japan.

Q&A
- Is the temple actually visible, or just an empty field?
- The original buildings are gone, but the stone platforms, foundation stones, and the layout of the precinct are clearly preserved and signposted. Gufuku-ji, the successor temple, stands on the Middle Hall foundation and can be entered for a small fee.
- What is special about the marble foundation stones?
- No other temple in Japan is known to have used marble for its column bases. Twenty-eight stones survive, all from the Middle Hall. They were once thought to be agate, but later analysis confirmed they are marble.
- How long should I plan for a visit?
- Allow forty-five minutes to an hour to walk the precinct, view the foundation stones, and visit Gufuku-ji. A sutra-copying experience can be arranged in advance and takes a further hour.
- How do I get there from Kyoto or Osaka?
- Take a train to Kintetsu Asuka or Kashiharajingu-mae station, then board the Akakame loop bus and alight at Kawahara. The site is two minutes on foot from the stop. Rental bicycles are available at Asuka station for those who prefer to combine the visit with other Asuka sites.
- Is this part of a UNESCO World Heritage Site?
- Not yet. Kawaharadera is one of the component sites of the candidate property "Asuka-Fujiwara: Archaeological Sites of Japan's Ancient Capitals and Related Properties," which is currently under UNESCO review with a decision expected at the 2026 World Heritage Committee.
