Enchin-Related Documents

A Patchwork of Tang Travel Permits

One scroll in this set is, quite literally, a patchwork. A certificate from the prefectural office of Taizhou, dated the third day of the twelfth month of 853, has five more permits pasted onto it end to end, each issued by a separate county office in Wenzhou and Taizhou as a Japanese monk made his way along the southeastern coast of China. The monk was Enchin (814–891), and these papers were his proof that he had leave to travel.

The eight scrolls known as the Enchin Documents, held at the Tokyo National Museum, gather records tied to one of the most consequential journeys in early Japanese Buddhism. Among them are Enchin's ordination certificate, an appointment to a court post, letters in his own hand, and the transit permits Tang officials handed him along the road. Designated a National Treasure in 1957, the group reaches back to the ninth century and survives in remarkable condition.

Enchin was a Tendai monk who trained on Mount Hiei, sailed to Tang China in 853, and returned some years later carrying scriptures and esoteric teachings. He went on to become the fifth head of the Tendai school and is revered as the founder of its Jimon branch, centered on Onjō-ji, the temple beside Lake Biwa better known as Mii-dera. The papers gathered here follow his life across ordination, court service, and his years abroad.

Why the Documents Matter

Most of what survives from ninth-century Japan is scripture or literary copy. Working administrative paper rarely lasted. That is part of what sets this group apart: it preserves real documents from both the Japanese court and the Tang bureaucracy, kept because one monk treated them as the records of his own standing and carried them home.

The transit certificates, called kugen, show how the Tang state controlled movement. A traveler entering a new district needed a document naming him and his purpose, and local clerks added their endorsements as he passed. Read together, the permits from Fuzhou, Wenzhou, and Taizhou map Enchin's route through the empire and record the actual workings of Tang transport law, a system Japan was then studying with great care.

In 2023 the museum's scrolls, joined with a far larger related group at Onjō-ji, were inscribed on UNESCO's Memory of the World register under the title Documents and Books Related to Chishō Daishi Enchin. The combined corpus runs to fifty-six National Treasures. Among the Onjō-ji holdings are the only two original kasho, full Tang travel passports, known to survive anywhere in the world; the Tokyo permits belong to the same family of road documents.

What to Look For

Several scrolls reward a close look. The ordination certificate of 833 is the formal proof that Enchin had entered the priesthood, the kind of paper a monk kept for life.

One document records his appointment in 850 as a naigubu, a cleric who performed protective rites for the emperor within the palace. An autograph note that Enchin attached explains an unusual circumstance: this style of certificate was not normally issued for such an appointment and was drawn up only through the special intervention of Fujiwara no Yoshifusa (804–872), then Minister of the Right. Enchin carried the paper to China as evidence of his rank.

His handwriting appears throughout, most directly in a personal letter dated the twenty-seventh day of the fifth month. Another scroll, a provincial report from Sanuki dated 867, opens with a petition brushed by an official named Fujiwara no Aritoshi, a passage long prized in the history of Japanese calligraphy. Standing before the ink of these ninth-century hands is the real reward of meeting the originals.

Seeing the Documents and the Wider Story

The Enchin Documents belong to the Tokyo National Museum in Ueno Park, the country's oldest and largest museum. Because ink and paper of this age are vulnerable to light, the scrolls are not on permanent view and appear only in occasional rotations, often around exhibitions on calligraphy, Buddhist history, or the museum's national treasures. High-resolution images are available year-round through the museum's e-Museum site, which lets you read individual documents far more closely than a display case allows.

To follow the rest of Enchin's story, the temple of Onjō-ji (Mii-dera) sits on the slopes above Lake Biwa in Ōtsu, an easy day trip from Kyoto. Its cultural-properties repository shows portions of the related document group, and the precinct, with its long views over the lake, ranks among the most rewarding in the region. The two surviving Tang passports are kept here.
