Jianzhen's Voyage to Japan (753): The Blind Monk's Mission

Jianzhen, known in Japan as Ganjin, was a Chinese Buddhist master who reached Japan in the winter of 753–754 after five failed attempts over ten years and the loss of his sight. Invited to bring proper monastic ordination to Japan, he set up the first regular ordination platform at Todai-ji in Nara and founded the temple of Toshodai-ji. His journey became one of the best-known stories of cultural exchange between Tang China and Japan.

Background: Japan’s search for a master

By the early eighth century Buddhism was the official religion of the Japanese court, but there was a problem. According to the vinaya, the code of monastic discipline, a monk could only be validly ordained by a quorum of at least ten fully ordained masters. Japan had no such body, and many people became monks simply to escape taxes.

In 733 the Japanese monks Yoei and Fusho went to China with an official embassy to find teachers. In 742 they visited Jianzhen at the Daming Temple in Yangzhou. Born in 688, he was then in his fifties, a respected teacher of the vinaya who had ordained tens of thousands of monks. When none of his disciples volunteered to go, he decided to go himself.

Five failed attempts

Leaving Tang China without permission was illegal, and the sea crossing was dangerous. The first attempt in 743 was stopped after a member of the party denounced the group to officials; the second was wrecked by storms soon after setting out. Two further plans were blocked by the authorities, partly because Jianzhen’s own followers wanted to keep their master in China.

The fifth attempt, in 748, was blown far to the south and ended on Hainan Island. The party spent years making its way back overland. On the way Yoei died, and Jianzhen, by then in his sixties, lost his sight to an eye disease around 750, according to his biography.

The sixth voyage

In 753 a Japanese embassy led by Fujiwara no Kiyokawa was preparing to sail home from China. Its members visited Jianzhen and offered passage. The Tang emperor Xuanzong had not agreed to let him go, so the vice-envoy Otomo no Komaro secretly took him aboard his ship.

The four ships left the Yangzi estuary late in 753. Kiyokawa’s ship, carrying the scholar Abe no Nakamaro, was driven off course to what is now Vietnam, and neither man ever returned to Japan. Komaro’s ship reached Akime in Satsuma, southern Kyushu, late in the twelfth lunar month, which fell in January 754 by the modern calendar. Jianzhen arrived in Nara in the second month of 754.

Work in Japan

The court welcomed him warmly. In 754 he set up an ordination platform in front of the Great Buddha at Todai-ji, where he administered the bodhisattva precepts to Retired Emperor Shomu, Empress Komyo and Empress Koken, and ordained some 400 people. A permanent ordination hall, the Kaidan-in, was built in 755.

In 759 he founded Toshodai-ji on land in the capital that had belonged to a prince, as a centre for the study of the vinaya. Its Golden Hall, built in the late eighth century, is one of the finest surviving buildings of the period. Jianzhen also brought Buddhist texts, relics and images, and later tradition credits him with spreading Chinese medical knowledge. He died at Toshodai-ji in 763.

Key people

• Jianzhen / Ganjin (688–763): vinaya master who founded the Ritsu tradition in Japan.
• Yoei (died 749) and Fusho: Japanese monks who invited him and accompanied his attempts.
• Otomo no Komaro: vice-envoy who carried him to Japan in defiance of the Tang court.
• Omi no Mifune (722–785): scholar who wrote his biography in 779, the main source for the journey.

Legacy

Jianzhen’s ordination system gave the Japanese state control over who could become a monk, and two further official platforms were later set up in the east and west of the country. Toshodai-ji remains the head temple of the Ritsu school and is part of the World Heritage Site of Historic Monuments of Ancient Nara.

A dry-lacquer statue of Jianzhen, seated in meditation with closed eyes, was made around the time of his death and is regarded as one of the oldest portrait sculptures in Japan. It has been taken to China for exhibition, including in 1980, as a symbol of friendship between the two countries.

Why it matters

Jianzhen’s persistence brought a fully regulated monastic system to Japan and tied Japanese Buddhism more closely to Tang practice. His story of repeated failure, blindness and eventual arrival remains a symbol of the human cost and value of the exchanges that shaped early East Asia.
