TOKYO: Tokyo stocks opened lower on Tuesday, weighed down by falls on Wall Street and a high yen against the dollar as well as concerns about rising virus cases in Japan.
The benchmark Nikkei 225 index was down 1.39 percent or 412.82 points at 29,272.55 in early trade, while the broader Topix index slipped 1.21 percent or 23.67 points to 1,932.89.

"Japanese shares are seen starting with falls as investors were disheartened by falls in US shares and a high yen" against the dollar, Toshiyuki Kanayama, senior analyst at Monex, said in a note.
Rising virus cases which have prompted calls for new states of emergency in the Osaka region and possibly Tokyo were also weighing on investors.
"Along with increased new coronavirus infections, the possibility of a state of emergency declaration is growing, which is turning on an amber light for economic recovery," Okasan Online Securities said in a commentary.
The new measures could involve tougher restrictions including asking shops and restaurants to close, local media has reported.Analysts said bargain-hunting purchases could still emerge later and support the market ahead of corporate earnings season in Japan.
The dollar fetched 108.04 yen in early Asian trade, against 108.15 yen in New York and 108.50 yen in Tokyo late Monday.
In Tokyo, Toyota was down 0.88 percent at 8,447 yen after a report the Japanese carmaker sees "cloudier" chip supply later this year.
