(Small Notes for the issue)
The Antarctic Treaty System (ATS), regulating utilization of Antarctica, was ratified by 12 countries including Japan, USA, Great Britain, France, and Former Soviet Union (Russia) in 1959 for the purpose of peaceful usage, freedom of scientific investigation, and implementation of international cooperation. This year marks 50th anniversary since ATS came into force in 1961.
