A Diplomat's Notebook from 1420
In the spring of 1420, a Korean official named Song Hui-gyeong (1376–1446) boarded a ship for Japan. He was 45, traveling as a return envoy for the young Joseon king Sejong, and his assignment carried a quiet second purpose: to watch Japan closely and write down what he saw. The result is the Rōshōdō Nihon Kōroku, a collection of Chinese-style poems and prose notes that follows his nine-month round trip between Hanseong, today's Seoul, and Kyoto.
The single bound volume preserved in Tokyo as an Important Cultural Property is the oldest surviving travel account of Japan written by a Korean. Its title joins the author's pen name, Rōshōdō, which means roughly "Old Pine Hall," to a phrase for a record of a journey to Japan.
Song wrote in verse because that was the language of educated diplomacy in his world. The poems still carry sharp, specific observation, and read together with their prose prefaces they amount to a foreign correspondent's dispatch from a country most of his readers would never see.
Why the Journey Happened
The timing was tense. In 1419, Joseon forces had launched a naval expedition against Tsushima, the island midway between the two countries that served as a base for the wakō, the armed seafarers who raided Korean and Chinese coasts. Koreans remember the campaign as the Gihae Expedition; Japanese sources call the wider episode the Ōei Invasion. A year later, with both courts uneasy about each other's intentions, Song was sent to the Muromachi shogunate to steady the relationship and to read the mood on the Japanese side.
He left Hanseong in the spring and reached Kyoto in the fourth month, then waited. The shogun, Ashikaga Yoshimochi, was observing a period of mourning, and the audience kept being postponed. Song's diary records how he handled the delay before finally presenting King Sejong's letter in the sixth month and sailing home in the tenth. The friction and the patience are both on the page.
The work was recognized as an Important Cultural Property on 4 July 1938. What earns it that standing is less its calligraphy than its testimony. Very little survives that describes ordinary fifteenth-century Japan from an outside vantage, and almost nothing of that age comes from a Korean hand.
What Song Saw
Much of the route ran by water, threading the islands of the Seto Inland Sea, so pirates appear often. Song writes about paying for safe passage and about the constant calculation of risk on those waters. He is not a flattering guest. He notes beggars and the sale of sex in the port towns, and he passes judgment freely.
The sharper his eye, the more useful the record. Halting near Amagasaki on the way back from Kyoto, he described farmers harvesting wheat in summer where rice had grown, then sowing buckwheat to cut at the start of winter. That single passage is one of the earliest clear descriptions of triple-cropping in a Japanese field, the kind of agricultural detail that local chroniclers rarely bothered to set down.
Elsewhere the tone softens. He writes warmly of a Japanese host who guarded and looked after him during his stay, and several poems turn on the ordinary human business of parting from people he had come to like across a hard border. War sits behind almost every page, and so does a wish for it to end.
The Book's Own Journey
The volume held in Tokyo has a history nearly as eventful as the voyage it describes. Scholars including Nakamura Hidetaka and Murai Shōsuke have traced its line of descent. It is said to come from a copy that Song's descendant Song Sun reworked and collated in 1556 from the author's own manuscript. During the Japanese invasions of Korea, around 1597, the book was carried to Japan. It then passed through the Hata, a Tokugawa retainer family, and later collectors before entering the Inoue household, whose name the manuscript still bears. The national heritage database records the work's date as 1420, the year of its composition.
The designated manuscript is privately owned and is not on public display, so there is no gallery to visit. The text itself is easy to reach. A fully annotated modern edition by the historian Murai Shōsuke appears in the Iwanami Bunko paperback series, and the work has long circulated in the classical anthology Zoku Gunsho Ruijū. Kyushu University keeps a faithful traced copy within its digital collections.
For travelers, the more rewarding approach may be to follow the route rather than the object. The sea lanes Song sailed still link the same islands, and a passage through the Seto Inland Sea, a stop in Kyoto where he waited on the shogun, or a look at the farmland around Amagasaki places you inside the geography of the diary. Reading a few of his poems beforehand gives the landscape a second layer.

Q&A
- Who wrote it, and when?
- Song Hui-gyeong, a Joseon official whose pen name was Rōshōdō, composed it during a 1420 mission to Japan, when he was 45.
- Can I see the original manuscript?
- No. The Important Cultural Property copy is privately held and is not exhibited. The complete text is available in print, including a modern annotated Iwanami Bunko edition.
- Why is a Korean travel diary a Japanese cultural property?
- Because of where it has lived. This copy was carried to Japan around 1597 and has been preserved here ever since, and it offers rare outside testimony about fifteenth-century Japanese society.
- What makes the account historically valuable?
- It records everyday matters that Japanese writers of the period usually ignored, such as farming methods, port life, and the reach of pirates, all seen by a careful and candid outsider.
- Is it written in Japanese?
- No. Like most formal East Asian diplomatic writing of the era, it is composed in literary Chinese, mainly as poems with prose prefaces.
