high of 38,600 yen after it said it planned to buy back up to 20
billion yen ($221 million) of its own shares, or 1.4 percent of
its issued stock.

from a previous estimate of between 173.30 billion and 177.00
billion yen, citing stronger advertising sales. It also raised
its annual dividend forecast to a range of 382-387 yen per share
