Former Manchukuo Embassy Site (Moto-Azabu, Tokyo)

The former Manchukuo Embassy (旧満洲国大使館) stood at what is now 3-4-33 Moto-Azabu, Minato-ku, Tokyo — the present site of the Embassy of the People's Republic of China in Japan. The building's history reflects the complex diplomatic and imperial dynamics of prewar and wartime Japan.

The site was originally the private residence of Viscount Goto Shinpei (後藤新平, 1857–1929), one of Japan's most influential statesmen who served as Foreign Minister, Mayor of Tokyo, Minister of Home Affairs, and Chief of Civil Administration of the Taiwan Government-General. The residence was designed by the renowned Czech-American architect Antonin Raymond in 1922, representing an early example of Western modernist architecture in Tokyo's diplomatic quarter.

Following Japan's establishment of Manchukuo (満洲国) on March 1, 1932, the puppet state required a diplomatic presence in Tokyo to maintain the fiction of its sovereignty. The former Goto residence was converted into the Manchukuo Embassy, and a series of ambassadors were appointed to represent the nominally independent state. Manchukuo, carved from China's northeastern provinces (Manchuria) following the Mukden Incident of September 18, 1931, was recognized by Japan and a handful of Axis-aligned nations but rejected by the League of Nations and most of the international community. The embassy in Tokyo served as a key node in the diplomatic architecture that Japan constructed to legitimize its continental empire.

The embassy building was destroyed during the catastrophic Tokyo air raid of May 25, 1945, one of the final major firebombing raids on the capital by the United States Army Air Forces. With Japan's surrender on August 15, 1945, Manchukuo itself ceased to exist, and its last emperor, Puyi, was captured by Soviet forces in Manchuria.

After the war, the site was allocated to the Republic of China (ROC) embassy. Following the normalization of diplomatic relations between Japan and the People's Republic of China (PRC) in 1972, the site was transferred to the PRC, which constructed a new embassy complex that occupies the location today. The transition from Manchukuo embassy to Chinese embassy encapsulates the dramatic arc of 20th-century East Asian geopolitics — from Japanese imperialism through Cold War realignment to the rise of modern China.
