Trade Day

What Is Trade Day?

Every June 28th is "Trade Day" (貿易記念日, Bōeki Kinenbi) in Japan. On June 28, 1859 (the 28th day of the fifth month of Ansei 6 in the old calendar), the Edo Shogunate issued a proclamation authorizing free trade with five Western nations — Russia, Britain, France, the United States, and the Netherlands — at the ports of Yokohama, Nagasaki, and Hakodate. This date marks Japan's full opening to international commerce after more than two centuries of the sakoku (鎖国) "closed country" policy, during which foreign trade was tightly limited — with the Dutch and Chinese at Nagasaki, and through a few other channels such as Tsushima and Satsuma. The ports actually opened on the 2nd day of the sixth month (July 1, 1859), and Yokohama marks June 2 as its Port Opening Day. Trade Day was established in 1963 by the Ministry of International Trade and Industry (MITI) to promote public understanding of trade's role in Japan's prosperity.

Japan's Economic Opening: From Isolation to Integration

The Ansei Treaties of 1858 — negotiated under the pressure of Commodore Perry's 1853 "black ships" visit — forced Japan to open its ports and set tariff rates that gave Western nations favorable trading terms. The opening was traumatic for many Japanese, triggering political upheaval and ultimately the Meiji Restoration of 1868. Yet the economic integration that followed drove Japan's remarkable industrialization: Western technologies, raw materials, and capital flowed in, while Japanese silk, tea, and porcelain flowed out, generating the foreign exchange that funded modern infrastructure, manufacturing, and education. Revising the unequal treaties became a long-term goal of the Meiji government, and Japan fully regained tariff autonomy in 1911.

From Tea and Silk to Electronics and Automobiles

Japan's export profile has transformed dramatically over more than 160 years of open trade. From the end of the Edo period through the Meiji era, raw silk was Japan's largest export, followed by tea; the Tomioka Silk Mill and related sites in Gunma were inscribed as a World Heritage Site in 2014. By the postwar period, Japan became a global leader in exporting manufactured goods: steel, ships, motorcycles, cameras, television sets, and automobiles. Today, Japan's major exports include automobiles, auto parts, industrial machinery, electronic equipment, and high-tech materials — reflecting an economy built on manufacturing excellence and technological innovation.

Japan as a Trading Nation

Trade is fundamental to Japan's economy. With limited domestic natural resources — Japan imports virtually all its oil, most of its coal, significant amounts of food, and many raw materials — Japan must export manufactured goods and services to pay for what it needs to import. This dependency has shaped Japan's trade policy, industrial strategy, and foreign relations throughout the modern era.

Fun Facts

• Japan's trade balance: Japan ran large trade surpluses through much of the late 20th century, accumulating the foreign exchange reserves and overseas investments that make it one of the world's largest creditor nations.
• WTO membership: Japan is a founding member of the World Trade Organization (established 1995) and an active participant in regional trade agreements including the CPTPP (Comprehensive and Progressive Agreement for Trans-Pacific Partnership).
