About the building
The embassy was designed by the U.S. firm of Delano & Aldrich. EmperorHirohito allegedly approved the design personally. The United States Commission of Fine Arts approved the design of the building on September 16, 1930. Erected in 1931, the building is in the Georgian Revival architectural style, with subtle elements of Japanese architecture. As originally designed, the embassy consisted of the ambassador's residence, two chancery buildings with strong Japanese architectural influence, a tea house, and tennis, gym, and other recreational facilities. The embassy features a cobblestone courtyard and driveway in front of the building. The original embassy building is now known as the Old Ambassador's Residence, and is located at 2516 Massachusetts Avenue NW. The original embassy and the two chancery buildings are two-and-a-half stories in height, with two underground levels. The total building height is about. The chancery buildings, which front onto Massachusetts Avenue NW, are about wide. The grounds were landscaped to complement Rock Creek Park, which abuts the rear of the embassy grounds. As of 1971, the Japanese Embassy was one of the few remaining formal estates in the city. The total cost of construction was $500,000. Following the attack on Pearl Harbor in December 1941, the embassy was seized by the United States government and re-purposed to house the Far Eastern Commission. The embassy was returned to Japanese control in April 1952. In 1959, then-Ambassador Koichiro Asagai and Tatsunosuke Takasaki, a member of the House of Representatives of the National Diet, proposed creating a replica of the rock garden at Ryōan-ji at the Japanese embassy. Constructed to commemorate the 100th anniversary of the first Japanese embassy to the United States, the scaled-down garden was finished in 1960. A small teahouse named Ippakutei, built in the style found at the Katsura Imperial Villa, is in back of the rock garden. The Japanese Embassy was added to the National Register of Historic Places on February 20, 1973.
Chancery
A stark, Modernist chancery building was completed in 1986. The chancery was built after Congress passed the Foreign Missions Act in 1982, which made it easier for embassies in the District of Columbia to expand their chanceries. Oddly, the new law significantly delayed construction of the chancery. The federal government lagged in promulgating regulations for the approval of chanceries, which meant that the chancery had to be approved by the District of Columbia Zoning Commission instead. But by the time the matter arose before the Zoning Commission in February 1983, the city was already in a multi-year process to revise its zoning regulations. The delay imperiled the funding provided by the Japanese government for the new building. Under intense pressure from the United States Department of State as well as the Japanese and Saudi Arabian governments, the city enacted emergency zoning regulations on April 12, 1983. Construction of the chancery was approved on June 10. It was designed by architect Robert B. Anderson of the Benham Group. The local Advisory Neighborhood Commission and the Sheridan-Kalorama Neighborhood Council applauded the design for "retaining the historical aspects" of the embassy compound. The project consolidated chancery offices from two rented buildings elsewhere in the District into a single structure on the embassy grounds. The chancery has 250 underground parking spaces, and a tunnel from Waterside Drive lead to the underground parking garage.
