TOKYO—Toyota Motor Corp is slowing production at as many as 11 plants in Japan because of rising COVID-19 infections among its workers and those at parts suppliers, it said on Thursday. That disruption, which comes amid a shortage of semiconductors that is already forcing it to curb output, could cut production plans this month by about 47,000 vehicles, a Toyota spokesperson said. Toyota on Tuesday said it expects to fall short of an annual target to build 9 million vehicles because it did not have enough chips. The company’s business year ends on March 31. There has been a surge in cases of the Omicron coronavirus variant in Japan since the start of the year. Daily coronavirus cases on Thursday rose to a record 46,199. By Maki Shiraki and Tim Kelly
