The Bank of Japan (BoJ) has pumped another 3 trillion yen¹ ($37bn; £23bn) into the country's financial markets in a bid to ensure calm.

日本银行再次向金融市场注入3万亿日元以保持市场稳定。

The move comes as the G7 nations agreed on a joint² intervention³ in currency markets to control the yen's volatilty（挥发性） .

The central bank has been injecting funds into the markets to maintain liquidty in the aftermath of last Friday's earthquake and tsunami⁴.

The latest move has taken BoJ's total funds injection to 37tn yen.

The bank has made fresh funds avaiable every single day this week as it tries to ensure that financial institutions in disaster-hit regions do not run out of funds.

The bank has also been battling to keep the value of the yen in check（受控制） after it hit its highest level since the Second World War against the US dollar earlier this week.
