*The eight days are set based on a document issued on 16 March 2022 by the MHLW's Headquarters for the Promotion of Countermeasures to Combat COVID-19 Infections to each prefecture and other authorities (based on the characteristics of the B.1.1529 strain (Omicron strain) while it was the predominant strain and the number of infected persons in each location.)
**Under current MHLWstandards, there is no quarantine period for those who have returned or entered the country other than the designated countries/regions and have received three doses of vaccine. The same policy is adopted for the Komaba Festival entry.
