The Nikkei has got the new week off to a flyer by recording a 1.5 per cent jump during today's (November 25th) trading session.
It jumped close to a new five-and-a-half year for the index, prompted by the yen falling in value compared to the US dollar.
After the gains, the Nikkei ended the session 237.41 points higher at 15,619.13, which was a new six-month high for the market, reports Reuters.
The broader Topix index was up as well, but not by as much, recording a 0.9 per cent increase to get the week off to a good start.
Today's gains follow on from the 1.4 per cent rise the Nikkei had last week, with the index now up by 50 per cent for the year.
It is now on track for its best weekly performance in more than 40 years, indicating the strength of the index in 2013 so far.
Honda and Yokogawa were among the big risers on the Nikkei during trading today.
