The city of Tokyo raised its coronavirus alert to the highest level on Wednesday. City officials acted after record-setting numbers of new infections were reported in the Japanese capital. Tokyo Governor Yuriko Koike described the situation in the city as “rather severe.” The fast spread of the virus in Tokyo could add to growing pressure on Japanese policymakers to protect the world’s third-largest economy. Some observers expect Japan’s economy to shrink at its fastest rate in many years because of the health crisis.
