Quick Answer: Who Was Jianzhen Ganjin?
Jianzhen (鉴真, Jiànzhēn, 688–763), called Ganjin in Japanese, was a Tang Buddhist monk who transmitted monastic precepts in Japan. He reached Japan in 753 and arrived in Nara in 754, where he conducted ordinations.[1][2]
- Before the voyage: He taught the Buddhist precepts in Yangzhou (扬州, Yángzhōu).[6]
- In Nara: He helped establish an ordination platform at Tōdai-ji and later founded Tōshōdai-ji (唐招提寺, Táng Zhāotí Sì).[3]
- In art: An early seated portrait at Tōshōdai-ji is made of hollow dry lacquer.[4]
The voyage matters because it brought a teacher qualified to confer precepts and train others.

Jianzhen (鉴真, Jiànzhēn) is remembered on both sides of the East China Sea. His journey began with an invitation to teach the precepts. In Nara it led to places where monks and nuns could formally receive and study them.[2][3]
Why Jianzhen Crossed the Sea
An early biography says that two Japanese monks approached him at Daming Temple in Yangzhou (扬州, Yángzhōu). They sought a teacher who could help establish formal ordination in Japan. Several attempts to cross failed. Jianzhen joined a Japan-bound diplomatic vessel on his sixth attempt. The accounts of the voyage belong to the wider history of maritime exchange that carried people and texts between East Asian ports.[2][6]
The two dates often given for his arrival describe different stages. He reached Japan in 753 and went on to Nara in the spring of 754. The chronology separates the successful crossing from his work in the capital.[1][2]
What He Established in Nara
At Tōdai-ji, an ordination platform gave monks and nuns a place to receive the monastic precepts formally. In 759 Jianzhen founded Tōshōdai-ji (唐招提寺, Táng Zhāotí Sì), where he established another platform and trained disciples. An ordination platform had a specific purpose within the institution, within a complex of buildings that could also contain halls for worship, as in many 佛寺.[1][3]
His work also offers a comparison with the Chinese pilgrim Yijing. Both brought Buddhist knowledge across water. Jianzhen’s legacy in Nara centered on conferring precepts and training a community that could continue the work.
What the Dry-Lacquer Portrait Preserves
Tōshōdai-ji preserves an eighth-century seated portrait with eyes closed and hands at rest. It is made of hollow dry lacquer with pigments. The image’s status as a National Treasure shows its importance in the history of Japanese Buddhist sculpture as well as the memory of a Chinese monk.[1][4][5]
