A magnitude 9.0 earthquake occurred on March 11, 2011, 14:46 at the epicenter about 130 km off the coast of Sanriku Northeast. The earthquake caused an onslaught of tsunami up to 15 m or more, had significant damage the coastal areas in the Tohoku region. After nine months of the tsunami, 15,842 deaths were reported, 3,481 missing, and about 18,000 people were spending their lives in the shelter]. Majority of those who lived in the shelter would end up living in the temporary housing later, where the huge environment and lifestyle changes are predicted to cause a great distress to the victims. The stress of the victims are not only limited to the immediate disaster stress response, but also after disaster stress response, which is chronic, and is predicted to leave an impact towards psychological and physical health. The death of stroke and cardiovascular events at one municipality were reported to be doubled than the previous year after three months of the Great Hanshin-Awaji Earthquake in 1995. Therefore it is thought that while considering the health issues of the disaster victims, the management of hypertension and dyslipidemia is essentially important as these are the major risk factors for cardiovascular events.
