New Tech Economy Japan

Japan was once seen as a pioneer when it comes to innovation. However, the country which is famous for Nintendo and the bullet train has now fallen behind some of its economic rivals. The government wants Japan to be at the forefront of high-tech and announced it would tap into its huge pension fund to assist local entrepreneurs. The BBC's Mariko Oi travels across Japan to see what impact the fund will have and explores whether it has the potential to be Asia's Silicon Valley.
