In Japan, schools must always be prepared for a potential earthquake. OYIS runs several drills a year for earthquake evacuations, including evacuating to safe zones.
OYIS runs fire drills at both campuses multiple times a year. Drills can be announced ahead of time or can be a surprise to test readiness.
Both campuses are prepared in the case of a tsunami following an earthquake. Luckily, the Tosabori campus is already quite high, and the Nakatsu campus is able to evacuate to the roof.
