Tokyo - Saba:
Japan's Nikkei index retreated on Monday, reversing early gains as investors booked profits after a strong rally and shifted their focus to anticipated corporate earnings.
The Nikkei index fell 0.8 percent to 41,115.60 points, after rising 0.2 percent earlier in the session.
Conversely, the broader Topix index fell 0.45 percent to 2,938.55 points.
