Timeline of the COVID-19 pandemic in Japan

The following is a timeline of the COVID-19 pandemic in Japan.

Background
The COVID-19 pandemic in Japan can be divided into five waves based on the genome sequence of the country's COVID-19 virus. The National Institute of Infectious Diseases (Japan) (NIID) has determined from its genetic research that the COVID-19 variant of the first wave is derived from the Wuhan type that is prevalent in patients from China and East Asia. After entering Japan in January through travellers and returnees from China, the virus resulted in numerous infection clusters across the country before moving towards its disappearance in March. Japanese medical surveillance confirmed its first case of the virus on 16 January in a resident of Kanagawa Prefecture who had returned from Wuhan.

The first wave was followed by a second one that originated from a COVID-19 variant of the European type that is traced back to early patients from France, Italy, Sweden, and the United Kingdom. Japanese medical surveillance detected the second wave on 26 March when the government's expert panel concluded the likelihood of a new outbreak caused by travellers and returnees from Europe and the United States between 11 and 23 March. The NIID has established that the majority of viruses spreading in Japan since March is the European type. This has led it to conclude that the data "strongly suggests" that the Japanese government has succeeded in containing the Wuhan variant and that it is the European variant that is spreading across the country.

Local media, including NHK, also pointed out that "in large cities such as Tokyo, where the number of infected people is increasing, there are voices concerned that the population movement will increase and spread." Legal circles are recruiting plaintiffs and lawyers for class action suits against the project under the name of "Stop Go To Travel." As the controversy grew, Yastoshi Nishimura, Minister of Economic revitalization in charge of COVID-19 response, held a press conference on 12 July and explained, "We must proceed with the campaign while paying attention to the spread of the infection.

Meanwhile, with the number of COVID-19 confirmed in Japan soaring recently, the Japanese government and Tokyo are engaged in a heated debate over who should be responsible. Japan's Chief Cabinet Secretary Yoshihide Suga said in a lecture in Hokkaido on the 11th, "It is no overstatement to say that the issue is obviously a 'Tokyo problem' and that Tokyo accounts for more than half of the new infections recently." In response, Tokyo Governor Yuriko Koike said at a press conference on the previous day, "Those who are in bad shape are appealing not to go out of Tokyo, but the government is trying to launch a 'Go To Campaign.' The response is a matter of the government." The 'Go-To campaign' is a tourism revitalization project actively pursued by the Abe government to promote domestic tourism demand, since Japan's tourism economy have been damaged by COVID-19 pandemic.
