Japan stocks continued to rise for fourth-straight-day Friday due to weaker yen against dollar. Investors eased fears over the U.S. economic situation but are still waiting for a number of companies to report their earnings.

The 225-issue Nikkei Stock Average increased 78.15 points, or 0.58 percent, from the previous day to 13,476.45. The broader Topix index of all First Section issues on the Tokyo Stock Exchange was up 10.74 points, or 0.83 percent, to 1,304.06. Among all the TSE first section issues, 969 increased and 606 decreased. The trading volume reached 1,576.06 million stocks or 1,913.3 billion yen. The Japanese currency is being traded in the level of first half of 102 yen per a U.S. dollar.

Key Japanese stocks such as Toyota, Nissan and Nippon Steel Corporation led upward trends Friday while trading firms like Marubeni and Mitsui declined.

Traders said, there is no directionality of Japanese stocks trend these days, so there is not much flow of money from overseas investors, according to Kabushiki Shimbun.
