TOKYO, Sept. 26 (Xinhua) -- Tokyo stock were mixed Tuesday morning as U.S. shares retreating overnight set a weak tone here in early trade, while a firmer yen against the U.S. dollar amid escalating tensions on the Korean Peninsular also inhibited buying.
The 225-issue Nikkei Stock Average edged down 20.29 points, or 0.10 percent, from Monday to 20,377.29.
The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, crept 1.17 points, or 0.07 percent, higher to 1,673.99.
Electric appliance, real estate and machinery-oriented stocks comprised those that declined the most by the morning break.
