 and other fields). is a Japanese abbreviation of this.

"The Institute of Physical and Chemical Research" was formerly used as an alternative English name, or a kind of subtitle, for RIKEN. But in 2003, when it became an Independent Administrative Institution, this name was officially discarded, and the English appellation is now just "RIKEN", in capital letters. The media sometimes refer to it as "Riken" or "the Riken institute".

"RIKEN" is pronounced as a single word: /ˈrɪkɛn/ (-ken). The full Japanese name, "Rikagaku Kenkyūjo", is sometimes pronounced "Rikagaku Kenkyūjo", this may be used less often but is not incorrect as it is merely an example of abbreviation.
