The Korean War breaks out in 1950 (Showa 25) with clashes between the Peoples Democratic Republic of Korea and the Republic of Korea around the 38th parallel, and ends with the Korean Peninsula partitioned into north and south. This war is fought with U.N. forces from 16 nations, primarily the U.S., using bases in Japan which bears the role of a source of materials and supplies. This 'special demand boom' rapidly revitalizes the postwar industry and economy, providing Japan with a new industrial structure. The need for metals and machinery spurs the heavy chemical industries. Toyota Motor Co., soon to become the symbol of Japanese industry, receives manufacturing orders for huge numbers of trucks. Shortages in many areas are eradicated. The streets of Tokyo are suddenly animated and there is a building boom. Buildings, naturally, require telephones. Despite intensive mass production, "We can't get you the phones right away," is a common refrain.
