"Riken" is anacronym of the formal nameRikagaku Kenkyūsho (理化学研究所), and its full name in Japanese isKokuritsu Kenkyū Kaihatsu Hōjin Rikagaku Kenkyūsho (国立研究開発法人理化学研究所) and in English is theInstitute of Physical and Chemical Research.

In 1913, the well-known scientistJokichi Takamine first proposed the establishment of a national science research institute in Japan. This task was taken on by ViscountShibusawa Eiichi, a prominent businessman, and following a resolution by theDiet in 1915, Riken came into existence in March 1917. In its first incarnation, Riken was a private foundation (zaidan), funded by a combination of industry, the government, and theImperial Household. It was located in the Komagome district ofTokyo, and its first director was the mathematician BaronDairoku Kikuchi.[citation needed]
In 1927, ViscountMasatoshi Ōkōchi, the third director, established the RikenConcern (azaibatsu). This was a group of spin-off companies that used Riken's scientific achievements for commercial ends and returned the profits to Riken. At its peak in 1939 the zaibatsu comprised about 121 factories and 63 companies, including Riken Kankōshi, which is nowRicoh.[citation needed]
After the war, the Allies dissolved Riken as a private foundation, and it was brought back to life as a company called Kagaku Kenkyūsho (科学研究所), or Kaken (科研). In 1958 the Diet passed the Riken Law, whereby the institute returned to its original name and entered its third incarnation, as a public corporation (特殊法人,tokushu hōjin), funded by the government. In 1963 it relocated to a large site in modern dayWakō then until 1970 inSaitama Prefecture, just outsideTokyo.
Since the 1980s Riken has expanded dramatically. New labs, centers, and institutes have been established in Japan and overseas, including:
in 2000, the Yokohama Institute, which now contains four centers for research in the life sciences
in 2002, the Kobe Institute, which contains the Center for Developmental Biology
In October 2003, Riken's status changed again, toIndependent Administrative Institution. As such, Riken is still publicly funded, and it is periodically evaluated by the government, but it has a higher degree of autonomy than before. Riken is regarded as the flagship research institute in Japan and conducts basic and applied experimental research in a wide range of science and technology fields including physics, chemistry, medical science, biology and engineering.[citation needed]
The Riken Super Combined Cluster is one of the world's fastestsupercomputers. In January 2006, Riken set up the Next-Generation Supercomputer R&D Center, with the purpose of designing and building the fastest supercomputer in the world, and in June 2006, it announced the completion of a one-petaFLOPS computer system designed specially for molecular dynamics simulation.Currently a new system, theK computer is being installed at Riken[needs update] and despite it being still not finished, it topped theLINPACK benchmark with the performance of 8.162 petaFLOPS, or 8.162 quadrillion calculations per second, with a computing efficiency ratio of 93.0%, making it the fastest supercomputer in the world at the time.[9][10][11][12] The complete project entered service in November 2012.[13]
