Tsukuba Science City represents one of the world's largest coordinated attempts to accelerate the rate of and improve the quality of scientific discovery. The city was closely modeled on other planned cities and science developments, including Brasilia, Novosibirsk's Akademgorodok, Bethesda, and Palo Alto. The city was founded by the merger of ?ho, Sakura, Toyosato, and Yatabe.
Beginning in the 1960s, the area was designated for development. Construction of the city centre, the University of Tsukuba and 46 public basic scientific research laboratories began in the 1970s. The city became operational in the 1980s to stimulate scientific discovery. Its constituent municipalities were administratively united in 1987. By the year 2000, the city's 60 national research institutes and two universities had been grouped into five zones: higher education and training, construction research, physical science and engineering research, biological and agricultural research, and common (public) facilities. These zones were surrounded by more than 240 private research facilities. Among the most prominent institutions are the University of Tsukuba (1973; formerly Tokyo University of Education); the High Energy Accelerator Research Organization (KEK); the Electrotechnical Laboratory; the Mechanical Engineering Laboratory; and the National Institute of Materials and Chemical Research. The city has an international flair, with about 3,000 foreign students and researchers from as many as 90 countries living in Tsukuba at any one time.
Over the past several decades, nearly half of Japan's public research and development budget has been spent in Tsukuba. Important scientific breakthroughs by its researchers include the identification and specification of the molecular structure of superconducting materials, the development of organic optical films that alter their electrical conductivity in response to changing light, and the creation of extreme high-pressure vacuum chambers
