The Port and Airport Research Institute (PARI) is a National Research and Development Agency and part of the National Institute of Maritime, Port and Aviation Technology. Since the launch of the Port and Harbour Laboratory, the predecessor of PARI, as a part of the Railway Technical Research Institute of the Ministry of Transport (MLIT, currently the Ministry of Land, Infrastructure, Transport and Tourism) in 1946, we have been dedicating research and development for ports and airports in order to contribute smooth and efficient construction, and improvement of related technologies.

PARI formulated the medium-to-long term plan in order to achieve the targets set by MLIT, focusing on ways to maximize our achievements in research and development as below.

Located in Yokosuka city, Kanagawa prefecture approximately fifty kilometers to the south of Tokyo, PARI operates multiple experimental facilities including a Large Hydro-Geo Flume that is the world's largest experimental wave flume capable of generating wind waves of maximum 3.5m and tsunami waves of maximum 2.5m. In addition to the facilities, almost eighty researchers, sixteen administrative personnel, and two administrators hold to the highest standards in order to maximize research output for actual projects.
