Following the declaration of a state of emergency for the Tokyo area, Japan has tightened its border control measures with stricter entry requirements for Japanese returnees and a fresh batch of entry procedures for business travelers from eligible countries.

The change to the travel policy, which was announced by the health ministry Friday night, is part of the government’s new measures in response to a surge in coronavirus cases across the country and around the world. The announcement comes a day after the government declared a state of emergency for Tokyo and three neighboring prefectures: Chiba, Kanagawa and Saitama.

Under the revised rules, nonresidents, with the exception of business travelers from 11 Asian nations under a reciprocal program, are not allowed to enter.
