Tokyo shares slipped Monday as market players were locked in earlier gains while overseas investors stayed away from the market due to the Christmas holidays.
The 225-issue Nikkei Stock Average ended down 31.03 points, or 0.16 percent, from Thursday at 19,396.64. The Tokyo market was closed Friday for a national holiday.
The broader Topix index of all First Section issues on the Tokyo Stock Exchange finished 5.68 points, or 0.37 percent, lower at 1,538.14.
Decliners were led by transportation equipment, oil and coal product, and mining issues.
