The Group of Seven (G7) countries intervened jointly to stem the yen's strength on Friday -- their first coordinated currency intervention in more than a decade -- after the yen soared to a record high of 76.25 yen per dollar.

The U.S. Federal Reserve, Bank of England, Bank of Canada and European Central Bank, which represents all 17 countries that use the euro, each separately confirmed they intervened to keep the yen's value from climbing.

The Ministry of Finance will announce on March 31 how much it spent on currency market intervention in March. ($1 = 81.045 Japanese Yen)
