Ryūkyū Tsūhō — The Only Coin of the Ryukyu Kingdom Born Under the Shadow of Satsuma Domain

Ryūkyū Tsūhō was born in Bunkyū 3 (1863). During this period, the Ryukyu Kingdom was under Satsuma Domain's influence and was in a highly complex political position. The Ryukyu Kingdom had been under the control of the Satsuma Domain since 1609 and, while formally independent, had to advance its policies under Satsuma’s surveillance. This background is believed to have greatly influenced the birth of Ryūkyū Tsūhō. The Satsuma Domain aimed to use the Ryukyu Kingdom as a transit point for trade between Japan and China to gain economic benefits. Ryūkyū Tsūhō may have been a means to demonstrate economic autonomy while reflecting the intentions of the Satsuma Domain by the Ryukyu Kingdom issuing its own currency. However, it is also believed that the creation of Ryūkyū Tsūhō was motivated by the Ryukyu Kingdom's intention to assert its identity. By trying to preserve their culture and economy, the Ryukyu Kingdom demonstrated its presence by minting unique currency. Nevertheless, the amount minted was extremely limited, and few were actually circulated. This may have been influenced by the economic constraints of the Ryukyu Kingdom and the strict supervision of the Satsuma Domain. The minting of Ryūkyū Tsūhō was more than just issuing currency; it was a symbol of the Ryukyu Kingdom’s political and economic challenges.

The minting of Ryūkyū Tsūhō was reportedly conducted on a very limited scale. The minting location and specific methods remain unknown, with various theories suggesting that unique Ryukyuan techniques were undoubtedly used. According to historical records, Ryūkyū Tsūhō was primarily minted with copper, but much about its exact composition and minting methods is shrouded in mystery. It is thought that artisans of the Ryukyu Kingdom were involved in minting Ryūkyū Tsūhō, utilizing unique Ryukyuan skills and materials to create this coin. Ryukyuan craftsmen may have independently developed upon techniques inherited from China and Japan, leveraging these skills to the fullest in producing Ryūkyū Tsūhō. However, due to the extremely limited quantity minted, the exact scale of this operation remains uncertain. Manufactured Ryūkyū Tsūhō were strictly managed by the government of the Ryukyu Kingdom, with their circulation being limited. Consequently, while Ryūkyū Tsūhō served as the currency of the Ryukyu Kingdom, it rarely reached the hands of the general populace. It is said that artisans minted Ryūkyū Tsūhō under the surveillance of the Satsuma Domain, yet specifics remain scarce, contributing to the enigma. The minting of Ryūkyū Tsūhō was an act symbolizing the economic independence of the Ryukyu Kingdom, as well as a technical achievement.

While Ryūkyū Tsūhō was minted to demonstrate economic independence, its circulation faced numerous constraints. Ryūkyū Tsūhō was primarily used within the Ryukyu Kingdom and was also employed in trade with the Satsuma Domain and other regions. However, the circulation was extremely limited, and its economic impact within Ryukyu was constrained. Ryūkyū Tsūhō held certain value in exchange rates with other coins, but its rarity made its usage among the populace limited. Since the types of currency in Ryukyu were limited at the time, Ryūkyū Tsūhō was often used in local commercial transactions. Public reactions varied, as the perceived economic value of Ryūkyū Tsūhō differed by region and trading partner. As part of the Ryukyu Kingdom’s economic policy and reflecting the intentions of the Satsuma Domain, the circulation of Ryūkyū Tsūhō was complex for the general populace. Though its economic impact was modest, Ryūkyū Tsūhō held a certain presence as a symbol of the Ryukyu Kingdom and its uniqueness. This context means the circulation of Ryūkyū Tsūhō reflects the complex political and economic environment of the Ryukyu Kingdom and, due to its rarity, holds special value for posterity.

In Meiji 12 (1879), with the Ryukyu Disposal, the Ryukyu Kingdom was abolished, and it was incorporated as Okinawa Prefecture into Japan. Consequently, Ryūkyū Tsūhō also ended its role. Ryūkyū Tsūhō symbolized the identity of the Ryukyu Kingdom, but under the new administration, its value quickly diminished, and it became obsolete. Post-abolition, while sometimes preserved as part of history, Ryūkyū Tsūhō was no longer used in actual economic activities. The abolishment of Ryūkyū Tsūhō, alongside the dissolution of the Ryukyu Kingdom, also influenced cultural identity in the region. Though the symbolic significance carried by Ryūkyū Tsūhō signified a historical loss for the local populace, it remained a part of Ryukyu's history and culture. The abolition of Ryūkyū Tsūhō marked the end of an era in Ryukyu’s history and also impacted the subsequent currency culture in Okinawa. In the present day, Ryūkyū Tsūhō is highly valued among antiquarian coin collectors as a rare historical heritage. Its value surpasses that of mere currency, serving as an important testament to the history of the Ryukyu Kingdom.
