NSA whistleblower Edward Snowden warned the people of Japan that their government is allowing the US to operate a mass surveillance program in their home country.

In a teleconference with more than 200 individuals, including journalists and lawyers, Snowden explained that almost all information people enter into their cellphones and computers is being gathered by the NSA in order to build a “pattern of life”.

Snowden was a contracted employee of the NSA working on a US airbase in Fusso Tokyo from 2009 to 2011. During that time he worked on a surveillance program for the US government.

In a separate interview Snowden highlighted US involvement in Japanese surveillance with the Act on the Protection of Specially Designated Secrets.

According to Snowden, this act was created at the request of the US and was designed by them. It allows Japanese government agencies and ministries the ability to classify information relating to defence and diplomacy. Anyone found leaking these secrets is subject to 10 years in prison and anyone who instigates leaks, like journalists, can face up to 5 years.
