Taiwan Governor-General Keelung Quarantine Station

The Taiwan Governor-General Keelung Quarantine Station (台湾総督府基隆検疫所) was a critical public health facility established at the Port of Keelung during the Japanese colonial period (1895–1945). As Taiwan's principal northern gateway and the island's busiest international harbor, Keelung was the primary point of entry for passengers and goods arriving from Japan, China, and Southeast Asia, making effective maritime quarantine essential to the colony's disease prevention strategy.

Following Japan's acquisition of Taiwan in 1895, the colonial government confronted severe epidemic threats including bubonic plague, cholera, malaria, and dysentery that ravaged the island's population. Governor-General Kodama Gentaro appointed Goto Shinpei — a physician trained in Germany who had previously served as chief administrative officer of the Temporary Army Quarantine Department — as head of civilian affairs. Goto implemented a comprehensive public health infrastructure modeled on European and Japanese systems. In 1899, the Office of the Governor-General promulgated the Regulations for Quarantine at Taiwan Seaports (臺灣海港檢疫規則), establishing permanent quarantine stations at Keelung and Tamsui based on Japan's domestic quarantine laws.

The Keelung Quarantine Station conducted systematic inspections of all incoming vessels, crew, and passengers. Ships arriving from plague- or cholera-affected ports were subject to mandatory quarantine periods, fumigation, and rat-proofing measures. The station maintained isolation wards for suspected cases, disinfection facilities, and bacteriological testing capabilities. As part of Keelung's broader port modernization, anti-rat walls were constructed along the harbor, and gas fumigation was employed to prevent rodent-borne plague transmission.

The quarantine system proved remarkably effective. Combined with the broader public health reforms — including the baojia mutual surveillance system for disease reporting, mandatory vaccinations, and a network of public physicians (公醫) stationed throughout the island — the colonial government achieved significant reductions in epidemic mortality. The Keelung station continued operations throughout the Pacific War, when the port's strategic military importance made disease control even more critical for troop movements and supply logistics.

After Japan's surrender in 1945, the quarantine facilities were taken over by the Republic of China government. The modern Taiwan Centers for Disease Control continues to maintain a quarantine office at Keelung Port, carrying forward the public health mission first established during the colonial era. The original quarantine station buildings have not survived, but the legacy of the institution endures in Taiwan's robust maritime quarantine infrastructure.
