Customs Day

What Is Customs Day?

Every November 28th is "Customs Day" (税関記念日, Zeikan Kinenbi) in Japan. On November 28, 1872, the Japanese government officially adopted the name "Zeikan" (税関, customs) for the offices responsible for controlling the import and export of goods and collecting duties — replacing the previous term "Kaisho" (会所). The Ministry of Finance (大蔵省, now 財務省) established November 28th as Customs Day in 1952 to mark this anniversary and to promote public understanding of the customs system and its role in Japan's economy and security.

Japan's Customs History

Japan's modern customs system dates from the late Edo period, when the forced opening of Japan's ports under the "Unequal Treaties" of the 1850s created an urgent need for customs administration. Under these treaties, Japan initially lacked tariff autonomy — customs rates were fixed by treaty with Western nations and could not be independently adjusted, a major economic grievance that Japan worked to overcome through diplomatic negotiations finally concluded in 1911. The recovery of full tariff autonomy was a significant milestone in Japan's achievement of equal international standing.

Customs in Modern Japan

Japan Customs (日本関税局, administered by the Ministry of Finance) today manages the flow of goods through Japan's seaports and airports — inspecting imports for contraband, collecting import duties and consumption taxes, enforcing trade regulations, and facilitating legitimate commercial trade. Japan is one of the world's largest trading nations, and its customs system processes millions of commercial shipments annually, balancing efficient trade facilitation with rigorous security screening.

Customs and Security

Beyond revenue collection, Japan's customs service plays a critical role in national security — intercepting narcotics, counterfeit goods, weapons, prohibited agricultural products, and other contraband. The "narcotics dog" (麻薬探知犬, mayaku tanchiken) units deployed at major airports and seaports are highly trained and effective tools in this effort. Japan Customs also works closely with international counterparts through the World Customs Organization (WCO) to address smuggling networks that cross national boundaries.

Fun Facts

• Yokohama Customs: Yokohama Customs (横浜税関) — one of Japan's oldest and most historically significant customs offices — operates from its distinctive neo-Renaissance "Queen" building (クイーンの塔) at Yokohama's waterfront, a landmark of the port's Meiji-era history.
• Duty-free shopping: Japan's tax-free shopping system for foreign visitors — which refunds consumption tax on eligible purchases made at registered retailers — is administered through the customs framework and has become a major factor in inbound tourism retail spending.
