Jin Sato, who served as mayor of the town of Minamisanriku, in Miyagi Prefecture, for 20 years, has been traveling across Japan to deliver lectures since stepping down in November, hoping to share lessons on disaster preparedness and mitigation.

¡°It¡¯s my way of repaying the support we received from people across the country after the Great East Japan Earthquake,¡± said Sato, now 74.

Soon after the massive earthquake and tsunami struck in March 2011, Sato was on the rooftop of the building housing the town¡¯s disaster management office, together with municipal employees and local residents.
