Manjirō Nakahama, at the young age of 14, was a fisherman who, along with four companions, found himself stranded on an island following a shipwreck. Their rescue arrived in the form of an American whaleship, which transported them to Honolulu. While his friends decided to stay in Honolulu, Manjirō ventured onwards to Massachusetts. This journey marked him as the first Japanese individual to set foot on the mainland of the United States.

Immediately following his arrival in Massachusetts, Manjirō embarked on a journey towards the California Gold Rush. His venture led him to San Francisco in May 1850. From there, he traversed up the Sacramento River via a steamboat and ventured deep into the mountains. After a few months, his efforts yielded a significant amount of gold, which he exchanged for approximately 600 pieces of silver. With this wealth, Manjirō made the decision to seek a path back to his homeland, Japan.

Upon his return to Japan, Manjirō was honored with the prestigious rank of a samurai. In addition to this, he pursued a scholarly career and served as a professor at Tokyo Imperial University.
