Tokyo's shares soared to their highest level in more than six months Thursday as a weaker yen boosted markets amid speculation that the Bank of Japan will launch further economy-boosting stimulus.

The benchmark Nikkei 225 index at the Tokyo Stock Exchange closed 1.56 percent, or 144.28 points, higher at 9,366.80, its highest closing level since early May. The broader Topix index of all first-section issues was up 1.23 percent, or 9.42 points, at 776.43. - Sapa-AFP
