Japan stocks and sushi: What do they have in common?

Japan's main stock index hit a six-year high on Thursday.

The Nikkei 225 index has gained nearly 50% this year - although it is well under half the highs seen in the 1990s.

Investors have been betting on a recovery in the Japanese economy - the world's third largest.

The BBC's Puneet Pal Singh takes a look at the reasons behind the buoyant investor morale using a plate of the popular Japanese dish, sushi.
