Our group is composed of wo sub-teams of software accreditation, and applied statistics. 　The mission of the software accreditation team is research and development about software evaluation technology in legal metrology. The area ranges from practice to theory: While we develop testing procedures according to software related OIML and JIS documents in legal metrology, we study verification tools in order to prove software correctness. The team also contributes to dissemination activities of these documents: We have published several commentary articles and given talks. We are members of the national mirror committee of OIML TC5/SC2 "Software". We also run a club for these purposes. 　The applied statistics team is researching the evaluation of measurement uncertainty and statistical methods for the interlaboratory comparisons. In addition, this team promotes the utilization of measurement uncertainty through the management of "Uncertainty Club" which is the user's club of measurement uncertainty.

1. Type evaluation tests and software inspections for legal metrology device.

2. Fundamental research on “Proof Net Calculator” for NP-Complete problem.

3. Researches on uncertainty evaluation, interlaboratory comparison, other problems on applied statistics.

4. Dissemination of uncertainty (Seminar, Commentary document, Website, Uncertainty club)
