There are various types of organizations in Japan; however, in the measurement standard field, which provides a platform for industry, they are not always strategic, cooperative and effective. Our goal is to brake down these barriers of each organization, and be able to provide comparable size of services to U.S. NCSLI.

The mission of NCSLI Japan is to support technical and managerial improvement in the field of Measurement Standards, Instrument Calibration, and Test and Measurement. The mission consists of 6 items.

1． 　Providing forums (technical exhibitions) for information exchange
2． 　Development of standard and recommended guidelines
3． 　Issuing publications on Measurement Technology and its management

5． 　Enlightening and promoting of Measurement Technology, and supporting for related organization
