Japan bear market: 'Third big dip in three weeks'

13 June 2013 Last updated at 11:41 BST

Japanese shares have tumbled after the yen hit a 10-week high against the US dollar, triggering concerns of a drop in exporters' profits.

The Nikkei 225 index fell 6.5% on Thursday. The drop put the market in bear territory, often defined as a 20% fall from a stock index's recent peak.

The index has fallen 22% since hitting a five-and-a-half-year high in May.

The BBC's Rico Hizon said there had been "a lot of volatility in the market."

"This is the third time in three weeks the Nikkei has plunged more than 5%," he added.
