The 225-issue Nikkei average ended up 376.21 points, or 1.21%, from Thursday at 31,524.22, its highest finish since July 25, 1990, when Japan experienced an asset price economic bubble.

The broader Topix index finished 33.41 points, or 1.55%, higher at 2,182.70, its highest close since Aug. 2, 1990.
