States Parties

Currently, 123 states are parties to the Convention with a further five having signed but not yet ratified.

The CCW seeks to prohibit or restrict the use of certain conventional weapons which are considered excessively injurious or whose effects are indiscriminate. It contains a framework treaty, which sets out procedure and the basic agenda, and five protocols that regulate specific conventional weapons (Japan is a state party to the framework treaty and protocols I to IV, including Amended Protocol II).   
Protocol I: restricts weapons with non-detectable fragments (entered into force in 1983)
Amended Protocol II: restricts landmines and booby-traps (entered into force in 1998)
Protocol III: restricts incendiary weapons (entered into force in 1983)
Protocol IV: restricts blinding lazar weapons (entered into force in 1998)
Protocol V: sets out obligations and best practices for explosive remnants of war (entered into force in 2006)
