TOKYO, Feb 17 (Reuters) - Japan's Nikkei share average fell on Friday with the market wary of a stronger yen and financials weakened as U.S. bond yields fell after comments by a senior U.S. Federal Reserve official were viewed as relatively dovish.
The Nikkei ended down 0.6 percent at 19,234.62 points. For the week, the benchmark index fell 0.7 percent.
Toshiba Corp sank 9.2 percent, after rating agency S&P Global said it could slash the conglomerate's rating if financial support from lenders includes any form of debt restructuring.
The broader Topix dropped 0.4 percent to 1,544.54 and the JPX-Nikkei Index 400 shed 0.5 percent to 13,855.47. (Repoting by Ayai Tomisawa; Editing by Kim Coghill)
