WIKILEAKS published evidence of the United States spying on its ally Japan yesterday, including a list of government and business targets.

The whistle-blowing website published its “Target Tokyo” list of 35 of US National Security Agency (NSA) targets — the Cabinet Office, the Bank of Japan and corporate giants Mitsubishi and Mitsui among them — going back at least eight years.

The latest release of leaked documents includes five NSA reports showing that Washington was keeping tabs on the Japanese cabinet’s discussions on climate change and trade policy.
