Tokyo stocks opened lower on Tuesday, with investor sentiment weighed down by a strong yen and a retreat from records on Wall Street.
The benchmark Nikkei 225 index fell 0.31 percent or 74.07 points to 23,555.27 in early trade, extending losses after four days of declines.
The broader Topix index was down 0.10 percent or 1.79 points at 1,878.66.
"The correction will likely continue as investors are discouraged by sharp drops in US stock prices and the strong yen," Okasan Online Securities chief strategist Yoshihiro Ito said in a note.
Wall Street fell on Monday ahead of a heavy calendar of corporate earnings reports this week, including from technology giants.
