The history of CWS, Headquartered in the United States, has begun when LARA supplies were sent to Japan as relief activity after the end of World War II. CWS Japan Committee opened their office in Tokyo in 1946 and was engaged in distribution of LARA supplies until 1952. Since then, CWS Japan Committee changed the name to Church World Services and continued their support activities through CAC supplies provision until 1963. The experience led to establishment of Japan Church World Service in 1958 and continuously promotes support activities for people with disabilities today. In 2011, in order to respond with emergency relief after the East Japan Earthquake and Tsunami, the office as CWS was re-opened in Tokyo and CWS Japan was founded.
