It has been 100 days since Prime Minister Shinzo Abe took office in Japan.

More than three months into the job, the economy is showing little signs of a turnaround.

Mr Abe is pursuing an ultra-easy monetary policy, which he hopes will urge consumers to spend, and companies to invest.

What led to the current state of these corporate giants?
