Japan central bank 'will keep calm and carry on'

Japanese stock markets have been making the headlines with huge swings in recent weeks, but the country's central bank is determined to "keep calm and carry on", the BBC's Rupert Wingfield-Hayes reports.

The Bank of Japan has just finished a two-day policy meeting but announced no major shift in its economic policies. In April it unveiled a huge stimulus package, in an effort to spur growth and end years of falling prices.
