The Nikkei index recovered its previous losses to end the day unchanged, as strong results for companies supported the market, despite the effect of the state of caution and anticipation ahead of the parliamentary elections at the weekend.
The Nikkei index fell eight points to close at 29,098.24 points, maintaining most of the gains it made in the past days, which amounted to about 500 points. The index had fallen earlier today to 28,870.25 points.
But the broader Topix index fell 0.23 percent to 2013.81 points.
Shares of Shinko Electric Industries led the gains on the Tokyo Stock Exchange, increasing 14.9 percent, and Maruwa Electronics rose 12.4 percent.
On the other hand, Canon shares fell 5.9% and Nidec Automobiles shares fell 2.9%.
