Business sentiment among large Japanese companies in the July to September period turned positive for the first time in three quarters, as progress in COVID-19 inoculations lifted expectations for an economic recovery, a government survey showed Monday.

The confidence index covering firms with capital of ¥1 billion ($9.1 million) or more registered plus 3.3, up from minus 4.7 in the April to June period, according to the joint survey by the Finance Ministry and Cabinet Office.

The figures are calculated by subtracting the percentage of firms reporting worsening conditions from those observing improvements.
