Tokyo - Tokyo stocks ended Friday morning trading slightly higher on a fall in US crude oil prices and the US dollar's advance against the yen.
The Nikkei 225 Stock Average inched up 13.37 points, or 0.1 per cent, to 12,970.17.
The broader Topix index of all first-section issues was slightly up 0.73 points, or 0.06 per cent, to 1,239.66.
While export-oriented issued were helped by a stronger dollar, gains were limited because of lingering concerns over the real-estate sector.
