(Updates prices after BOJ policy decision)

TOKYO, Dec 19 (Reuters) - Japan's Nikkei share average rose more than 1% on Friday and ?the 10-year government bond yields hit a 19-year ?high at 2% after the Bank ?of Japan raised interest rates ?to a ?three-decade high and signalled more policy tightening to come.

The ?10-year yield extended ?an earlier rise, following the central bank's as-expected rate hike to ?0.75%, hitting the 2% ?mark ?for the first time since May 2006.

The level acted as a symbolic ?ceiling during Japan's decades-long struggle with deflation.

Equity investors took cues from an overnight U.S. session, where a rally in chip stocks lifted all ?three ?major Wall Street indexes.

The Nikkei extended its rally slightly after the BOJ's policy ?announcement, rising 1.3% to 49,629.26 as of 0400 GMT.

The broader Topix rose 0.8% to 3,382.59.

Ten-year JGB futures fell as much as 0.5 yen to 132.84 yen, ?the lowest since June 2008. Bond prices move inversely to yields. (Reporting by Kevin Buckland; Editing by ?Sumana Nandy, Rashmi Aich and Subhranshu Sahu)
