Tokyo City. World War II wreaked widespread destruction of most of the city due to the persistent Allied air raids on Japan and the use of incendiary bombs. The bombing of Tokyo in 1944 and 1945 is estimated to have killed between 75,000 and 200,000 civilians and left more than half of the city destroyed. The deadliest night of the war came on March 9–10, 1945, the night of the American "Operation Meetinghouse" raid; as nearly 700,000 incendiary bombs rained on the eastern half of the city, mainly in heavily residential wards. Two-fifths of the city were completely burned, more than 276,000 buildings were demolished, 100,000 civilians were killed, and 110,000 more were injured. Between 1940 and 1945, the population of Japan's capital city dwindled from 6,700,000 to less than 2,800,000, with the majority of those who lost their homes living in "ramshackle, makeshift huts". 1945–present After the war, Tokyo became the base from which the United States under Douglas MacArthur administered Japan for six years. Tokyo struggled to rebuild as occupation authorities stepped in and drastically cut back on Japanese government rebuilding programs, focusing instead on simply improving roads and transportation. Tokyo did not experience fast economic growth until the 1950s. After the occupation of Japan ended in 1952, Tokyo was completely rebuilt and was showcased to the world during the 1964 Summer Olympics. The 1970s and the 1980s brought new high-rise developments. In 1978, Sunshine 60 – the tallest skyscraper in Asia until 1985, and in Japan until 1991 – and Narita International Airport were constructed, and the population increased to about 11 million in the metropolitan area. The Edo-Tokyo Open Air Architectural Museum has historic Japanese buildings that existed in the urban landscape of pre-war Tokyo. Tokyo's subway and commuter rail network became one of the busiest in the world as more and more people moved to the area. In the 1980s, real estate prices skyrocketed during a real estate and debt bubble. The bubble burst in the early 1990s, and many companies, banks, and individuals were caught with mortgage-backed debts while real estate was shrinking in value. A major recession followed, making the 1990s Japan's "Lost Decade", from which it is now slowly recovering. Tokyo still sees new urban developments on large lots of less profitable land. Recent projects include Ebisu Garden Place, Tennōzu Isle, Shiodome, Roppongi Hills, Shinagawa (now also a Shinkansen station), and the
