Japan’s journey to developing its own currency system is a fascinating tale of cultural exchange, economic evolution, and political necessity. It all began in the 7th century, when Japan, inspired by China’s Sui and Tang dynasties, established its own “Ritsuryō” legal system. While this system laid the foundation for Japan’s political structure, the introduction of currency marked a major milestone in the country’s economic development.

A Glimpse of Ancient Coins: The First Step

Before the establishment of the Ritsuryō system, Japan’s economy primarily relied on bartering goods. However, the introduction of coins became a game changer. Early immigrants from China, known as “Wakō” in Japan, brought with them Chinese currency such as the Han Dynasty’s “Ban Liang” and “Wu Zhu” coins. This exchange of cultural and economic practices would eventually lead to the minting of Japan’s own currency.

For many years, scholars believed that Japan’s first homegrown coin was the “Wadōkaichin,” which was minted in 708 AD, modeled after the Tang Dynasty’s “Kaiyuan Tongbao” coin. But in 1998, an archaeological dig in Asuka Village in Nara Prefecture uncovered 33 coins from the late 7th century, known as the “Fuhon Sen.” These discoveries reshaped our understanding of Japan’s early currency history.

Copper, Silver, and the Ban on Silver Coins

Both the “Wadōkaichin” and the “Fuhon Sen” were copper coins, as silver was also in use at the time. The Japanese Emperor, as recorded in the Nihon Shoki, issued a decree stating: “From now on, only copper coins shall be used; no more silver coins.” This was Japan’s first step in regulating its currency system.

Between 708 and 958 AD, Japan issued 12 types of copper coins, collectively known as the “Twelve Imperial Coins.” Although Japan also minted silver and gold coins, these were primarily for ceremonial purposes and were not used in everyday trade.

Copper Coins and Economic Growth

As Japan’s economy expanded, the demand for currency grew. However, Japan faced a significant challenge: a shortage of copper and a lack of advanced refining techniques. Over time, the quality of domestically minted copper coins deteriorated, and their value dropped. By the middle of the 10th century, Japan gradually shifted away from copper coins and entered a period where goods like rice, silk, and cloth served as currency.

During the 11th to 13th centuries, Japan began importing large quantities of Chinese copper coins, further fueling trade between the two nations. Japan’s rich gold and silver resources allowed it to export vast amounts of precious metals to China in exchange for copper coins. This trade was so robust that, during the Southern Song Dynasty, Japanese merchants purchased so many copper coins from Taizhou that they eventually disappeared from the region.

The Ming Dynasty and the Japanese Gold Rush

With the establishment of the Ming Dynasty, China initially prohibited the circulation of copper coins. However, the Ming government was quite liberal in its foreign trade dealings, frequently gifting vast amounts of copper coins to neighboring countries, including Japan. The Yongle and Xuande periods saw a flood of Chinese coins into Japan.

By the 16th century, Japan’s economy began to shift once again. As the demand for currency increased, Japan turned to precious metals. The introduction of the “kaitai” technique for refining silver allowed Japan to extract more silver, and this metal began circulating as currency. By the mid-16th century, the Takeda clan in Kai Province had developed a well-organized gold currency system, which later became the basis for the Tokugawa shogunate.

Tokugawa Shogunate: Standardizing Currency

After the unification of Japan by Oda Nobunaga, his successor Toyotomi Hideyoshi introduced the “Ten Shō Dōban” gold and silver currency system. This was mainly used for military and administrative purposes, but it laid the groundwork for the standardization of currency in Japan.

Hideyoshi’s successor, Tokugawa Ieyasu, established the Edo Shogunate and monopolized the country’s gold and silver mines. The Tokugawa government issued coins such as the “Kōō Tōbō” copper coin and set fixed exchange rates between gold, silver, and copper, effectively creating a unified currency system for the nation.

The Meiji Era and the Birth of the Yen

The Edo period came to an end in the 19th century with the opening of Japan’s borders to Western trade. With foreign merchants flooding Japan and taking advantage of the country’s gold and silver discrepancies, Japan’s economy faced an inevitable crisis. In 1871, the Meiji government, inspired by Western monetary systems, implemented a sweeping reform with the introduction of the yen as the official currency.

The yen, initially pegged to the value of gold, was a revolutionary shift. The establishment of the Bank of Japan in 1882 further stabilized the currency, ushering in the era of paper money.

Conclusion: A Modern Legacy

Japan’s journey from ancient copper coins to the modern yen is a testament to the country’s resilience and adaptability in the face of both domestic challenges and foreign influences. Over the centuries, Japan’s currency system evolved to reflect the dynamic changes in its political, social, and economic landscapes, ultimately laying the foundation for the nation’s modern economy.
