Asuka-dera

Asuka-dera is a Buddhist temple in the village of Asuka in Nara Prefecture. It was built between 588 and 596 by Soga no Umako, the most powerful minister of the Yamato court, and is considered Japan’s first Buddhist temple with a full set of monastery buildings. Its early names were Hōkō-ji (“temple where the Dharma flourishes”) and Gangō-ji; people also simply called it Asuka-dera, “the temple of Asuka”.

Before Asuka-dera, Buddhist images in Japan were kept in private houses or small shrines. Asuka-dera was something new: a planned complex of large wooden buildings on stone foundations with tiled roofs, laid out around a pagoda that held relics of the Buddha. It introduced to Japan not only a religion but also a whole package of technology — surveying, foundation-building, carpentry, roof tiles and bronze casting.

Most of the original temple disappeared long ago. What survives on the site is a small hall, rebuilt in the Edo period, standing where the central golden hall once stood, and inside it the bronze Asuka Great Buddha. Around it, archaeologists have traced the foundations of the original buildings under the fields.

Buddhism began in India in the fifth century BCE and spread through Central Asia to China and then to the kingdoms of the Korean peninsula. From Baekje, in south-western Korea, it reached Japan. According to the Nihon Shoki (Chronicles of Japan), King Seong of Baekje sent a gilt-bronze image of the Buddha, banners and sutras to the Yamato ruler Kinmei. The Chronicles date this to 552; other early sources give 538.

The Yamato court was divided. The Soga clan, which managed foreign relations and many immigrant craftsmen, wanted to accept the new faith; the Mononobe and Nakatomi clans, who were tied to the worship of the native gods (kami), warned that the gods would be angry. When an epidemic broke out, the opponents blamed Buddhism and threw an image into a canal. The quarrel ended in 587, when Soga no Umako and his allies defeated Mononobe no Moriya in battle.

Buddhism had also arrived privately earlier: a later chronicle says that an immigrant named Shiba Tatto (Shiba Tatsuto), grandfather of the sculptor Tori, was already worshipping a Buddhist image in Yamato in 522. After 587, Umako could build a temple on a scale never seen before, and Asuka-dera was the result.

The Chronicles give an unusually detailed building record. In 588 Baekje sent Buddhist relics, monks and a team of specialists: two temple carpenters, one master of metal fittings for the pagoda top (rohan hakase), four tile masters (wa hakase) and one painter. The site chosen was the house of a man named Konoha, which was torn down. In 590 workers went into the mountains to cut timber; in 592 the Buddha hall and corridors were raised; in 593 relics of the Buddha were placed in the foundation of the pagoda’s central pillar; in 596 the temple was declared complete, and Umako’s son was put in charge.

The same year, two foreign monks came to live there: Hyeja (Eji) from Goguryeo and Hyechong (Eso) from Baekje, who together were called the “pillars of the Three Treasures”. Hyeja was also the Buddhist teacher of Prince Shōtoku, so Asuka-dera was a meeting place for the court, immigrant craftsmen and monks from two Korean kingdoms.

Roof tiles are the best evidence of Baekje’s role. The Korean Encyclopedia explains that the wa hakase (tile master) was a Baekje title for specialist tile makers, and that the tiles of Asuka-dera, with their lotus-petal designs, introduced tiled roofing to Japan and trained Japanese potters as tile makers. Two families of early tile designs have been found at the site, both in a style linked with Baekje.

Excavations in 1956–57 revealed an unusual plan. A pagoda stood at the centre. Around it were three golden halls (kondō): one to the east, one to the west and one to the north, the northern one on the main axis. A roofed corridor enclosed this group, with the middle gate to the south and a lecture hall behind the corridor to the north. This “one pagoda, three golden halls” plan is not found in later Japanese temples and differs from the usual Baekje plan of one pagoda and one hall in a line.

The central position of the pagoda tells us what mattered most. A pagoda is a monument that houses relics of the Buddha’s body, so placing it at the centre, surrounded by image halls, made the relics the heart of the temple. Over the next century, Japanese temples gradually moved the image hall to the centre and the pagoda to the side — at Hōryū-ji the hall and pagoda stand side by side, and at later temples in Nara the pagodas were placed outside the main enclosure.

Korean scholars have compared the three-hall layout with temple sites of Goguryeo; the Korean Encyclopedia entry on Asuka-dera describes the plan as reflecting Goguryeo influence rather than a direct copy of Baekje practice. This matters because it shows that Asuka-dera was not simply the product of one Korean kingdom: Baekje builders, a Goguryeo monk, and perhaps plans known through Goguryeo all contributed.

In 605, according to the Chronicles, Empress Suiko ordered large images to be made in bronze and embroidery, and the king of Goguryeo sent 300 ryō of gold to help. The bronze Shaka (Śākyamuni) Buddha was installed in 606, or in 609 according to another temple record. Its maker was Kuratsukuri no Tori (Tori Busshi), from a family of saddle makers descended from the immigrant Shiba Tatto. His skill in casting and lacquer, learned in the saddle workshop, served him in making Buddhist images; later, in 623, he made the Shaka Triad of Hōryū-ji.

The seated Buddha is 275.2 cm high. It has suffered greatly: the golden hall burned in 1196, the statue later sat in the open for a time, and it was repaired many times. A survey in 1973 concluded that only part of the face — from the forehead to above the nose — and three fingers of the right hand were original. Later studies in 2015–2017 extended this somewhat, but still found that most of the body is later repair. Even so, because it has stayed on its original site for over 1,400 years, it is treasured as the oldest datable Buddha image in Japan in its original location.

Its style, where it survives — the long face, almond-shaped eyes and faint smile — resembles the Tori style of the Hōryū-ji triad, which art historians trace back to Buddhist sculpture of the Northern Wei in China, transmitted via the Korean peninsula.

For the Soga and the court, a temple was at once a religious foundation, a political statement and a technological showcase. Buddhism promised merit for the patron and his ancestors, healing from illness and protection for the state. The Chronicles repeatedly connect temple building with vows made in times of danger: Umako is said to have vowed to build a temple if he defeated the Mononobe, just as Prince Shōtoku vowed Shitennō-ji in the same campaign.

A tiled hall on stone foundations towering over the Asuka valley also displayed power in a new language. For three centuries Japanese elites had shown their status by building great burial mounds. Asuka-dera moved that display from the tomb to the temple: instead of a mound for one leader, a permanent complex where monks performed rituals for the living and the dead. Within a few decades dozens of clan temples appeared around Asuka and Ikaruga, and the building of giant keyhole-shaped tombs came to an end.

Finally, the temple was a school. Monks taught Chinese writing and Buddhist texts, craftsmen trained apprentices, and the court learned how to plan and finance large projects. The skills developed at Asuka-dera — laying out buildings on an axis, making tiles in quantity, casting large bronzes — were later used for palaces and capitals such as Fujiwara-kyō and Heijō-kyō. In that sense, the first Japanese state capitals were built partly on lessons learned in the first temple.

Asuka-dera was part of a wave of temple building across East Asia. In Baekje, King Wideok founded Wangheungsa at Buyeo in 577, in memory of a dead prince; a relic container dated to that year was found in its pagoda foundation in 2007. Baekje’s capital, Sabi, had been built by King Seong, the king whom the Chronicles credit with sending Buddhism to Japan. In Silla, Buddhism had been officially accepted in the 520s after the martyrdom of Ichadon, and the great temple of Hwangnyongsa was being built in the capital, Gyeongju.

In China, the Sui dynasty reunited the country in 589, the year after Asuka-dera was begun. Its founder, Emperor Wen, was a great patron of Buddhism and had relics distributed to pagodas across the empire in the early 600s — a Chinese parallel to the relic deposit in Asuka-dera’s pagoda. In India, the monastic university of Nalanda was flourishing and would soon attract Chinese pilgrims.

Further west, Justinian’s Hagia Sophia in Constantinople, finished in 537, was already the largest church in the Christian world, and in 597 Pope Gregory the Great sent missionaries to the Anglo-Saxons in England. In Arabia, Muhammad was born around 570, and in the Maya lowlands the city of Tikal was in its so-called hiatus after a defeat in 562. Across Eurasia, rulers were sponsoring great religious buildings that displayed both faith and new building technology — and Asuka-dera was Japan’s first contribution to that story.

Asuka-dera stood at the centre of court life in the seventh century. According to the Nihon Shoki, it was at a kickball game at this temple that Prince Naka no Ōe first met Nakatomi no Kamatari, and in the coup of 645 Naka no Ōe used the temple as his stronghold against the Soga. After the fall of the Soga, the temple became an official state temple rather than a clan foundation.

When the capital moved to Heijō-kyō (Nara) in 710, the temple’s institution followed: in 718 Gangō-ji was established in the new capital, where it became one of the great temples of Nara. The original site remained as “Hon-Gangō-ji” (the original Gangō-ji) but declined. In 1196 a fire started by lightning destroyed the pagoda and the golden hall; by 1447 the Great Buddha was sitting in the open air, exposed and damaged.

The present small main hall was rebuilt in 1826, in the Edo period, with help from patrons in Osaka, and the temple, now called Angoin, belongs to the Shingon school. The site was designated a National Historic Site in 1966. It is now one of the component sites of the “Asuka–Fujiwara” group of ancient capitals, which Japan has nominated for World Heritage status.

The excavations of 1956–57 were among the first large-scale excavations of an early temple in Japan. They established the three-hall layout, measured the corridors and gates, and uncovered the foundation stone of the pagoda. The eastern and western halls stood on two-tier stone platforms, ranked below the finer platforms of the pagoda and central hall — a hierarchy of foundations that shows careful continental-style planning.

The pagoda foundation held ritual deposits: beads of jade and glass, metal ornaments, horse trappings, pieces of armour and other objects. Many of these are of the same kinds found in kofun burial mounds. Archaeologists read this as evidence of continuity: the Soga honoured the relics of the Buddha with the same prestige goods that elites had placed in tombs. Asuka-dera thus stands at the meeting point of the Kofun period and the Buddhist Asuka period.

Recent work has refined the chronology of the roof tiles, the construction sequence and the history of the Great Buddha. The finding that most of the statue is later repair has not reduced its importance; rather, it has made the Great Buddha a case study in how damaged objects carry memory across centuries.

The date of Buddhism’s arrival is the first point of disagreement. The Nihon Shoki gives 552; the Jōgū Shōtoku Hōō Teisetsu and the temple history of Gangō-ji give 538. Many scholars now prefer 538, because the Nihon Shoki’s chronology for this reign has problems and because 552 may have been chosen for its significance in Buddhist calculations of the decline of the Dharma. Others point out that both dates are uncertain and that the real process was gradual, beginning with immigrants like Shiba Tatto before any official gift.

Korean and Japanese narratives emphasise different actors. Korean scholarship, such as the Korean Encyclopedia’s entry, stresses that Asuka-dera was built by Baekje craftsmen, housed Goguryeo and Baekje monks and received Goguryeo gold, making it a key monument for understanding how Korean Buddhist culture was transmitted to ancient Japan. Japanese scholarship accepts these contributions but tends to emphasise the Soga clan’s role as organiser and patron, the training of Japanese craftsmen, and the continuity with native Kofun traditions seen in the pagoda deposits. Both are supported by the evidence; they differ mainly in which part they put in the foreground.

The origin of the plan is also debated. The three-hall layout does not match the one-pagoda-one-hall plan of excavated Baekje temples such as Wangheungsa, and has been compared with Goguryeo sites. Some scholars therefore see a Goguryeo model, perhaps brought by Hyeja’s circle; others suggest that Baekje itself may have had such plans that have not yet been found, or that the plan was a local adaptation. Until more early temple sites are excavated in Korea and China, the question remains open.

Finally, the word “transmission” itself has been questioned. Rather than imagining culture flowing one way from a “source” to a “receiver”, many historians now describe a network: Chinese Buddhist models, Korean kingdoms competing for allies, immigrant families in Japan and a Japanese elite choosing what to adopt. Asuka-dera is best understood as the product of all of them.
