Nearly 1.5 million working-age people in Japan are social recluses, according to a new government survey, with a fifth citing the Covid-19 pandemic as the main reason for their withdrawal. The most common reason respondents gave for their social withdrawal was "quitting jobs" in the survey released Friday. The Cabinet Office said there was no past data directly comparable to the new figures.
