TOKYO, Feb 3 (Reuters) - Japan's Nikkei share average ended at a seven-week high on Friday, underpinned by the Nasdaq's strong performance overnight, with Sony Group and others leading the charge after reporting strong growth outlook.

The Nikkei rose 0.39% to close at 27,509.46, its highest close since Dec 16. The index rose 0.46% for the week.

The broader Topix edged up 0.26% at 1,970.26 but lost 0.6% for the week.

"Companies' outlook was clearly reflected in their share prices, like Sony," said Takamasa Ikeda, senior portfolio manager at GCI Asset Management.

"Investors wanted to confirm their outlook before making active bets."
