Tokyo - Tokyo stocks closed lower on Thursday, with major telecom firms plunging after one company announced it would slash fees, while fresh concerns emerged over the prospects for the Chinese economy.
The benchmark Nikkei 225 index fell 1.06%, or 232.81 points, to end at 21 687.65, while the broader Topix index lost 0.85%, or 14.07 points, to 1 632.05.
Telecoms nosedived after the industry leader NTT Docomo said it would cut fees under government pressure, with its shares plunging 14.71% to ¥2 426.
Its rival KDDI plummeted 16.14% to ¥2 360 on the news, and SoftBank dropped 8.15% to ¥8 310.
The Nikkei business daily meanwhile reported KDDI would tie up with internet titan Rakuten on payment, logistics and roaming services.
Rakuten, which confirmed the report later, rose 3.01% to ¥787. The company has said it will launch its mobile service later next year.
The dollar fetched ¥112.89 in early Asian trade, almost unchanged from New York, but lower than ¥113.22 in Tokyo late on Wednesday.
Chinese factory activity slowed in October, official data showed on Wednesday, adding to a growing list of bad news for the Asian giant as it struggles to maintain economic momentum in the face of US tariffs and a weakening yuan.
The Purchasing Managers' Index (PMI), a key gauge of factory conditions, came in at 50.2 for the month, down from 50.8 in September, the National Bureau of Statistics said.
The official PMIs "were the latest downbeat indicators," Mark Williams of Capital Economics said in a note to clients.
"The Markit manufacturing PMI due on Thursday is the next indicator to watch," he said.
The fall in Japanese shares is in part a rebalancing, in "reaction to a rise of more than ¥460 in the Nikkei index yesterday," Toshiyuki Kanayama, senior market analyst at Monex said in a commentary.
In Tokyo shares, Panasonic fell 5.64% to ¥1 179 after it reported on Wednesday its first-half to September net profit fell 4.5% on-year to ¥113.6bn ($1bn).
Some carmakers were lower, with Toyota down 0.58% at ¥6 576 after it said it would recall more than 1.6 million cars due to airbag problems.
Nissan was down 0.29% at ¥1 024.5.* Sign up to Fin24's top news in your inbox: SUBSCRIBE TO FIN24 NEWSLETTER
