I still don’t know how widely used Ivermectin was in Japan, but he also did not push for mandatory lockdowns and the prefecture governments followed his example and did not impose their own. There were retail and hospitality businesses that closed, but they were offered monetary compensation first. They were never forced to close. The closest thing Japan had to a vaccine mandate for entry was shortening the 2 week quarantine period by 4 days if you were vaccinated. Abe went against the coordinated global plan and instead did what seemed best for Japan at the time.
