That's according to the Nikkei Asian Review (the media company that bears the same name as the stock index). Here's what it had so say:

The Nikkei index on Thursday logged 10 straight trading days of gains for the first time in over 27 years, as the yen's continued weakening against the U.S dollar helped export-related issues and strong performances by European and U.S. stocks overnight boosted investor sentiment.

Japanese stocks have been boosted by a weak yen, which fell to a 12-year low against the dollar in trading on Thursday.
