Tokyo - Stocks in Tokyo were mixed in Friday morning trading as higher oil prices sent commodity share prices up but financial issues fell as investors nervously sized up the large debts those companies still have on their books from the financial crisis.

The benchmark Nikkei 222 Stock Average inched up 18.97 points, or 0.19 per cent, to 10,257.62.

Tokyo's broader-based Topix index fell, however, by 2.96 points, or 0.33 per cent, to 901.15.

On currency markets at 9 am (0000 GMT), the dollar traded at 90.79-83 yen, up from Thursday's 5 pm quote of 89.53-54 yen.

The euro traded at 1.4954-56 dollars, up from 1.4934-35 dollars Thursday, and at 135.81-82 yen, up from 133.71-75 yen. (dpa)
