Emperor Gotoba's Handwritten Letter with His Personal Seal

A Dying Emperor's Letter, Sealed with His Own Hands

On the ninth day of the second month of 1239, on a small island in the Sea of Japan, a sixty-year-old man dipped both palms in vermilion ink and pressed them onto a letter he had just finished writing. Thirteen days later he was dead. The man was Retired Emperor Gotoba, once the most powerful figure in Japan, and the letter, known as the Gotoba Tenno Shinkan Otein Okibumi, survives today at Minase Jingu Shrine in Osaka Prefecture. It was designated a National Treasure on March 29, 1952.

The title needs unpacking for readers new to Japanese documents. Shinkan means a document in an emperor's own hand. Otein refers to the handprints. Okibumi is a set of final instructions, in practice a will. Put together: the testament of Emperor Gotoba, written himself and sealed with his handprints, dated the ninth day of the second month of Ryakunin 2.

It is a single handscroll, ink on paper, measuring 39.0 by 101.2 centimeters. Eighteen years of exile separate this sheet of paper from the throne rooms of Kyoto.

From Cloistered Rule to Exile on Oki

Gotoba took the throne in 1183 as a child of three and abdicated in 1198, but abdication in his era meant the opposite of retirement. As retired emperor he ran the court for over two decades, compiled the celebrated poetry anthology Shin Kokin Wakashu, forged swords with his own hands, and watched the Kamakura shogunate consolidate military power in eastern Japan.

In 1221 he gambled everything. The uprising he launched against the shogunate, remembered as the Jokyu War, collapsed within a month. The shogunate's forces, said to number in the tens of thousands, marched on Kyoto and won decisively. Gotoba was banished to Nakanoshima, one of the Oki Islands off the coast of present-day Shimane Prefecture. He never saw the capital again.

He spent nineteen years there, writing poetry and practicing Buddhist devotions. In early 1239, sensing that an illness would not pass, he wrote this letter to Minase Chikanari, a courtier of the Fujiwara line who had long served him and whose family kept watch over the emperor's beloved country villa at Minase, between Kyoto and Osaka. The document grants Chikanari rights over lands including Minase and Inouchi in Settsu Province, and asks one thing in return: that his memory be honored and prayers said for his soul. One line is still quoted by the shrine today, asking again and again that his afterlife be prayed for.

Why This Document Is a National Treasure

Documents written personally by Japanese emperors, called shinkan, are rare survivors, and a number of them hold National Treasure status. Within that small group, this one is exceptional for a reason you grasp the instant you see it: the two vermilion handprints pressed directly onto the text.

Handprints on imperial autographs are extraordinarily uncommon. Specialists point to only a handful of comparable examples, such as the testament of Emperor Gouda at Daikakuji Temple in Kyoto. A seal or signature authenticates a document; a pair of inked palms does something more visceral. It fixes the physical presence of the writer onto the paper at a precise moment, in this case a man within two weeks of death.

The calligraphy carries its own weight. Visitors who have seen the scroll at exhibitions often remark on the size of the hands and on the firmness of the brushwork, surprising in a text that includes a sober admission that the writer's condition is worsening by the day and that the outcome is all but settled. Gotoba was one of the finest calligraphers of his age, and his hand here remains controlled, dense, and direct. The document is also a primary source of the first order: a deathbed statement, in the principal's own words, from the central figure of the Jokyu War, the conflict that redrew the balance between court and warrior government for the next six centuries.

Seeing the Okibumi, and What It Built

Be aware before planning a trip: the original scroll is not on regular display. Minase Jingu preserves it as the founding object of the shrine itself, and the document leaves the treasury only for major loan exhibitions. It appeared at the Kyoto National Museum's National Treasures exhibition in 2017, at the Kyushu National Museum in 2018, and at the Japan National Treasures exhibition held in Osaka in 2025. Checking upcoming exhibition schedules at Japan's national museums is the realistic way to see it. A replica can be viewed at the Gotoba-in Museum on Nakanoshima in the Oki Islands, near the site of his residence in exile.

The shrine that grew from the letter, however, welcomes visitors year-round, and it rewards the short trip. In 1240, the year after Gotoba's death, Minase Nobunari and Chikanari, father and son, built a memorial hall called a mieido on the grounds of the ruined Minase villa, following the wishes set down in the okibumi. The hall enshrined the emperor's portrait and the testament itself. In 1494 Emperor Gotsuchimikado granted it the divine title of Minase-gu, and the shrine now venerates three emperors exiled after the Jokyu War: Gotoba, Tsuchimikado, and Juntoku.

The grounds hold more than history. A spring called Rikyu no Mizu, the Water of the Detached Palace, is the only source in Osaka Prefecture selected among Japan's one hundred famous waters, and locals line up daily with bottles. The Toshintei tea pavilion, an Important Cultural Property associated with the early Edo period, and a guest hall connected to Toyotomi Hideyoshi stand on the grounds. Look closely at the front gate for a dark handprint said to have been left by the thief Ishikawa Goemon, a folk legend that pairs oddly well with a shrine founded on a pair of imperial handprints.

Getting There and What Else to See

Minase Jingu sits in the town of Shimamoto, on the Osaka side of the border with Kyoto Prefecture. From Minase Station on the Hankyu Kyoto Line the walk takes about ten minutes; JR Shimamoto Station is roughly fifteen minutes on foot. Trains from Osaka-Umeda or Kyoto-Kawaramachi reach Minase in under half an hour, which made this corridor a favored retreat for Gotoba eight centuries ago and makes it an easy half-day trip now.

The Suntory Yamazaki Distillery, the birthplace of Japanese whisky, is about a ten-minute walk from the shrine; tours require advance reservation. Across the prefectural border, the town of Oyamazaki offers the Asahi Group Oyamazaki Villa Museum of Art and hiking trails up Mount Tennozan, site of the 1582 Battle of Yamazaki. Pairing the quiet shrine precincts with a distillery tour fills an unhurried afternoon along one of Japan's oldest travel corridors, the riverside route between Kyoto and Osaka.
