Japan's Nikkei ended an eight-day rally on Friday after U.S. President Donald Trump said he is ready to quickly ratchet up a trade war with China, rattling Asian markets.
The Nikkei share average shed 0.1 percent to 22,842.18 points by midmorning.
The benchmark index hit the psychologically important mark of 23,000 this week, but has failed to stay above that level at the market close.
The Nikkei looked set for a 1.0 percent gain for the week and a little more than that for the month. The broader Topix dropped 0.2 percent to 1,735.84.
