Japan's Nikkei share average rose modestly on Tuesday after the yen dropped to a six-year low against the dollar, lifting exporters such as Honda Motor Co and Sony Corp, but weak crude oil prices weighed on energy shares.
The Nikkei rose 0.4 percent to 15,774.21 points by
mid-morning, moving close to its seven-month high of 15,829.38 hit last week, Reuters reported.
Honda gained 1.2 percent and Sony added 1.3 percent, while Advantest Corp advanced 2.5 percent.

"Investors are uncertain about Japan's growth so they want to wait until good news comes out (before investing aggressively)," said Hiromichi Tamura, chief strategist at Nomura Securities, citing Monday's revised Japanese GDP report, which showed the economy contracted more than initially expected
in the second quarter.
Oil shares and trading houses underperformed, with Inpex Corp falling 1.2 percent, Mitsubishi Corp shedding 0.1 percent and Sumitomo Corp declining 0.1
percent after Brent crude fell below $100 a barrel for the first time in 16 months.
The broader Topix gained 0.1 percent to 1,299.89 and
the JPX-Nikkei Index 400 added 0.1 percent to
