TOKYO, Oct 6 (Reuters) - Japan's Nikkei average inched up 0.2 percent in see-saw trade on Tuesday as bank shares such as Mitsubishi UFJ Financial Group climbed after Goldman Sachs upgraded the U.S. banking sector.
The benchmark Nikkei rose 17.31 points to 9,691.80. At one stage, it fell as far as 9,628.67, its lowest since July 22.
The broader Topix added 0.5 percent to 871.63.
Mazda Motor shot up 7.6 percent after it said it would raise up to $1.1 billion in a share sale to invest in hybrid and other technologies in what analysts said was a long-overdue bid to close the gap with rivals. It also halved its net loss forecast for the year to March. (Reporting by Aiko Hayashi)
