The yen's latest slide came after Abe said in an interview with the Nikkei newspaper published on Friday that the BOJ should consider maximising employment as a monetary policy goal to help boost the economy.
The yen selling also gained momentum after data showed on Friday Japan logged a current account deficit in November for the first time in 10 months, as exports fell due to weak global demand and energy imports increased.

"The currency (euro) appears to be slightly undervalued vis-a-vis EZ sovereign spreads," saidRichard Franulovich, senior currency strategist at Westpac Securities in New York.
