TOKYO, Sept 4 ― Tokyo stocks opened lower today on fears that the global economy may be slowing, after US data pointed to weakness in the manufacturing sector.

The benchmark Nikkei 225 index was down 0.19 per cent or 40.07 points at 20,585.09 in early trade, while the broader Topix index was down 0.32 per cent or 4.77 points at 1,506.02.

"Japanese investors are reacting to a trend in the US market and the US manufacturing data,” Mizuho Securities said in a note to clients.

"A wait-and-see attitude is seen dominating the market” it added.

Wall Street stocks tumbled Tuesday as new tariffs in the US-China trade war took effect, while US data suggested weakness in the manufacturing sector.

Washington and Beijing imposed new levies on September 1, with the US now levelling 15 per cent tariffs on an assortment of consumer goods and China responding with its own duties.

Meanwhile, "against expectations for an unchanged outcome, the US ISM manufacturing index contracted in August clipping the wings of a rising US dollar, (and) also dragging equities,” Rodrigo Catril, senior strategist at National Australia Bank, said in a note.

The dollar fetched ¥105.86 (RM4.20) in early Asian trade, against ¥105.94 in New York.

In Tokyo, losses were led by exporters, with the auto giant Toyota sliding 0.68 per cent to ¥6,957 and its rival Nissan trading down 1.20 per cent at ¥648.4.

Some electronics were also lower, with Panasonic trading off 1.17 per cent at ¥809.7 and Sharp down 0.80 per cent at ¥1,111.

On Wall Street, the Dow ended down 1.1 per cent at 26,118.02. ― AFP
