The Western Army Infantry Regiment (西部方面普通科連隊 Seibu Hōmen Futsū-ka Rentai), is a (battalion sized) Japanese light infantry regiment that specializes in amphibious operations. Its main purpose is to defend remote islands in Japanese territorial waters, specifically to the Kyushu region, including Okinawa. The regiment is based at Sasebo in Nagasaki.

The WAIR was created on March 27, 2002 in order to defend remote islands in the western part of Japan in case of an invasion or enemy attacks, although they are also mandated to assist in search and rescue efforts in case their assistance is needed. It consists of Ranger-trained JGSDF soldiers and at the initial formation, it consisted of 600 soldiers.

In August 2010, a proposal was being considered by the Japanese government to convert a conventional [battalion strength] regiment from either the 8th Division or the 15th Brigade into a "US-style" amphibious unit, effectively giving the Western Army a battalion of marines for dealing with contingencies.

In 2013, troops from the Western Army Infantry Regiment deployed from the JS Hyuga and JS Shimokita for an amphibious warfare exercise in California.

As of June 2013, as part of an ongoing expansion of defense capabilities in the Western Army's area of responsibility, the MOD were considering creating a special "isle assault unit", whose role would be the recapture of remote Japanese islands that had been invaded by a foreign power. It would share this mission with the pre-existing Western Army Infantry Regiment, itself currently undergoing an expansion in manpower and equipment (e.g. increase in authorised strength to 680 effectives, & adding (initially 4) AAVP-7A1's to its TOE). Equipment for the new unit on the other hand, may ultimately include the Maneuver Combat Vehicle and the Light-weight Combat Vehicle (LCV) System alongside MV-22 Ospreys.
