The nationwide state of emergency over the coronavirus outbreak has resulted in less traffic, less air pollution and, less predictably, a growing running population.

In this time of self-isolation, jogging around the neighborhood has become for many Japanese the primary motivation to get out of the house and get some fresh air. Those overseas, however, are facing stricter rules.

In Malaysia, 11 joggers, including four Japanese, were arrested for ignoring the movement control order late last month, and in Paris a ban on jogging and all physical exercise between 10 a.m. and 7 p.m. came into effect on April 8.
