Shukuhaku Ryoyo/宿泊療養　n.

(Lodging recuperation) 

A method to quarantine patients of COVID-19 with mild or no sympton. In this approach, the patients stay in a hotel or other accommodation that local government provides. Although accommodation and meals are provided for free, cleaning and washing should be done by the patients themselves. Patients are prohibited from smoking and drinking. Catering from outside (including care packages from their family) are not accepted. Services provided to the patients may vary by prefecture.
