Japanese agency giant Dentsu has reported a modest rise in revenues for its fiscal year.

The holding company -- the world's fourth-largest ad group -- posted a 3% sales increase to Y1,749 billion ($15.3bn; €12.8bn; £8.7bn) for the twelve months to March. Dentsu was lifted by the improving economy in Japan, where it controls 25% of the advertising market.

Net profits jumped 35% to Y30.8bn thanks to a one-off Y12.7bn gain linked to the company's pension fund. Operating profits, however, slipped 0.7% to Y46.6bn.

Dentsu expects revenues to climb 6% in its current fiscal year, reflecting the continued economic upturn and the effect of the Olympic Games this summer. It is predicting a 2% rise in pre-tax profits.
