Gunma Prefecture issued guidance to a social welfare corporation operating a disability support facility following an investigation into an accident in which a male high school student (17 at the time), who attended a disability support facility in Ōra Town, Gunma Prefecture, fell ill and died during a sea swimming outing. The prefecture cited a “delay in transporting him to a hospital” as a contributing factor and pointed out that countermeasures against aspiration of seawater had not been discussed, stating that “risk management was not in place.”
