Japan's Nikkei share average ended a shade lower in holiday-thinned Christmas trading on Friday, as utilities and financial stocks fell.
The Nikkei closed 0.11 percent lower at 18,769.06, having oscillated between gains and losses for most of the session. Trading volumes were thin given most global financial markets were shut for the Christmas holiday.
Elsewhere, stocks in China, the only other major Asian market open for trading Friday, climbed higher.
Nikkei fell 1.1 percent during the week, extending their losing streak to four weeks.
