Letters from an Emperor Who Wanted to Become a Monk
Around 1307, a man who had once ruled Japan sat down to write to a Buddhist priest. He was not issuing an edict. He was asking a favor, and he kept asking, in his own hand, with rising urgency. The writer was Go-Uda, by then a retired and newly ordained emperor; the priest was Kenjun, an esoteric master at Daigo-ji in the wooded hills southeast of Kyoto. Three of those private letters survive. Long ago they were remounted together onto a single handscroll, and that scroll now carries Japan's highest cultural ranking.
The full title reads Go-Uda Tennō Shinkan Tōryū Shōryū Kyōkai. Shinkan means an autograph written by an emperor's own brush, a category Japanese collectors prize above almost any other manuscript. The remaining words point to the subject of the correspondence: the carrying-on and flourishing of a particular esoteric lineage. The Agency for Cultural Affairs classifies the work as komonjo, historical documents, dates it to the Kamakura period, and records its author plainly as Emperor Go-Uda.
One of Only Two Emperors to Take Up the Esoteric Path
Go-Uda lived from 1267 to 1324. He came to the throne as a child, stepped down at twenty, and spent the rest of his life drawn ever deeper into Shingon esoteric Buddhism. His posthumous name is itself a clue: it means "the later Uda," chosen in homage to Emperor Uda, who four centuries earlier had become a practicing esoteric master. In the whole sweep of Japanese history, only these two emperors went so far as to train as ajari, fully qualified masters able to perform the rites and pass the teaching on.
In 1307, after the death of his empress Yūgimon-in, Go-Uda took religious vows. The following winter he received an advanced initiation in the Hirosawa branch of Shingon and the religious name Kongōshō. But he wanted more. He had set his heart on the Sanbōin lineage transmitted at Daigo-ji, and on a goal that few clerics would have dared name aloud: to reunite the two great streams of Shingon, the Ono and Hirosawa branches, and so restore the religion to something closer to its founding shape under Kūkai. The three letters are where he made that case, in private, to the one teacher who could grant it.
What the Three Letters Actually Say
The correspondence reads like a negotiation conducted under emotional pressure. In the first letter Go-Uda writes to Kenjun, who had fallen ill, saying that should the priest not recover he himself hopes to inherit the lineage, and asking to call on him while there is still time. He states that he has already mastered the secret rites of the Hirosawa branch and that, admitted to the orthodox succession, he might bring the divided teaching back into one.
Kenjun did not simply agree. He set conditions, including that Go-Uda hold himself to the proper discipline of an esoteric practitioner. In the second letter the cloistered emperor accepts those terms and goes further, promising to take up residence at Daigo-ji's Hōon-in. The third letter closes the matter with a vow to devote himself wholly to the prosperity of the lineage. The phrase he uses there, tōryū shōryū, the flourishing of this school, is what later gave the whole scroll its name. Read in sequence, the letters move from plea to pledge, and Kenjun, persuaded, transmitted the innermost teachings of the Sanbōin lineage.
Where to See It and What Else to Find There
The scroll belongs to Daigo-ji, a temple founded in 874 by the monk Shōbō and now a UNESCO World Heritage Site spread across a whole mountainside in the Fushimi ward of Kyoto. Its holdings run past 100,000 objects, and fragile komonjo like these letters are rotated into view only on occasion, during the special exhibitions held each spring and autumn at the temple's Reihōkan treasure hall. Anyone hoping to see the actual documents should check the current exhibition schedule before setting out, since on most days they rest in storage.
There is plenty to fill a visit regardless. The lower precinct holds a five-story pagoda completed in 951, the oldest surviving building in Kyoto, and a Kondō main hall that Toyotomi Hideyoshi had moved here from Wakayama. The Sanbō-in, the temple's administrative cloister, fronts a garden Hideyoshi is said to have designed himself. Daigo-ji sits about ten minutes on foot from Daigo Station on the Kyoto Municipal Subway Tōzai Line, an easy ride from the city center.

Q&A
- Who wrote these letters, and to whom?
- Emperor Go-Uda wrote them in his own hand after he had abdicated and taken Buddhist vows. The recipient was Kenjun, an esoteric priest of Hōon-in at Daigo-ji, from whom Go-Uda hoped to receive the Sanbōin lineage.
- What does the title mean?
- Shinkan marks the work as an imperial autograph. The rest of the title refers to the carrying-on and flourishing of the lineage, drawn from a phrase Go-Uda himself used in the third letter when he vowed to support the school.
- Why is it counted as one scroll when there are three letters?
- The three separate letters were remounted together onto a single handscroll, which is why the official record lists the quantity as one scroll while the title notes three documents.
- Can visitors actually see the documents?
- They are kept at Daigo-ji and shown only during occasional special exhibitions at the Reihōkan, generally in spring and autumn. Check the temple's exhibition listings in advance, as the scroll is usually in storage.
- What made an emperor's request so significant?
- Go-Uda was one of only two emperors in Japanese history to train as a Shingon master. His letters record both a personal religious devotion and an ambitious plan to reunite the two main branches of Shingon, making them valuable to historians as well as calligraphers.
