I'm sure Japan has. This is a normal continuity of business protocol, with a cascade down reporting lines. If one fails to respond, cascade to the next layer of reporting down. And have an actual cascade plan in-hand, at home, at work, and on mobile. All businesses should have one, and they are useful for many reasons. Test it annually or more, depending on business. And have results posted back - who responds, who doesn't.
