John Manjiro: How Experience Across the Ocean Became Knowledge

A fisherman from Tosa was shipwrecked, learned about navigation abroad and returned to explain overseas affairs. The outline is familiar as an adventure across the sea. This account follows the less easily compressed question of what happened after he was rescued.

Education in a town, experience aboard ships and the work of putting experience into words belonged to different settings. Each helped create circumstances in which what one person had learned could become useful to others. Rescue alone does not explain those later activities.

The connection between these stages is the article’s interpretive thread. It follows the institutional accounts without presenting knowledge transfer as one formal programme or a policy designed in advance. Manjiro’s later role becomes visible through several kinds of learning and communication.

The whaling ship’s captain was Whitfield. Rescue did not mean that the castaways were immediately delivered back to Japan. Their next destinations differed from the fishing community they had left, and eventually differed from one another.

The companions left the ship in Hawaii, while Manjiro travelled on with the captain to the American mainland. The men who had shared a shipwreck and rescue did not thereafter share exactly the same route. This is one point where a collective experience became a distinct individual biography.

For Manjiro, time at sea was followed by schooling in Fairhaven. That transition matters to what he later brought home: he encountered a town and its daily life as well as a ship. The surviving accounts therefore lead beyond the island and the rescue vessel.

After school, Manjiro again sailed aboard whaling ships. His first experience aboard an American vessel had begun as a rescued castaway. Later voyages followed a period of education, linking life on land with further experience at sea.

The institutional accounts thus describe more than information acquired from books. English and mathematics were part of his learning, while living and working among different people aboard a ship supplied another setting in which knowledge and experience could meet.

This distinction helps explain the returning witness. When asked about overseas affairs, he was someone who had lived in foreign ships and towns. It does not follow that every story later attributed to him was independently verified; the narrower point is the combination of settings in his biography.

Manjiro’s experiences also reached people through someone who listened and wrote. The Tosa artist Kawada Shoryo compiled Hyoson Kiryaku. The Sakamoto Ryoma Memorial Museum explains that in 1852 he heard the returned Manjiro describe voyages and overseas affairs.

There are two roles in this account: the person who experienced the events and the person who arranged what he heard into writing and illustrations. Treating the work as Manjiro’s own diary would erase the recording process between the journey and the surviving text.

That process is part of the history of transmission. Experience did not become a book without another person’s work. This article follows the museum’s account of the compilation and does not claim a new complete decipherment of the original manuscript or a comparison of every surviving version.

Another form of knowledge associated with Manjiro is the English conversation book Eibei Taiwa Shokei. In the Kochi University copy, the conversation examples are accompanied by small phonetic writing, including katakana, and corresponding Japanese text.

The adopted script’s observation of image twelve includes a short expression concerning how a person is feeling. The article uses that limited observation to discuss the arrangement of the page. It does not turn one inspected page into a verified transcription of the whole book.

Knowing a language and preparing something from which another person can learn it are different activities. The book makes that distinction concrete. Its arrangement offers a way to follow the passage from one speaker’s experience to a form that could be consulted beyond a face-to-face conversation.

In 1860, Manjiro crossed the Pacific again aboard Kanrin Maru as an interpreter. A role list in a travel record reproduced in the 1938 compilation Bakumatsu Gunkan Kanrin Maru distinguishes him as interpreter from Katsu Rintaro, also known as Katsu Kaishu, as commander.

The treaty-ratification delegation travelled aboard the American warship Powhatan. That vessel and Kanrin Maru had different roles. The latter carried Japanese participants, including Katsu, and Americans, including Brooke; communication between people aboard was one of the tasks for which Manjiro’s experience mattered.

The role list establishes a distinction in titles, not a complete account of who carried out each task throughout the crossing. The article does not transform an assessment of practical assistance into an official command appointment. Daily navigation and decisions would need to be followed through additional records.
