The 2011 Tohoku Earthquake was huge damage to Japan, especially, along the coasts of Miyagi, Iwate, and Fukushima. There was catastrophic damage by tsunami created by this earthquake. Japan frequently has been affected by strong earthquake before Tohoku Earthquake. Much has been emphasized about the impacts of human and physical visible damages since disasters struck and there are a lot of studies about disaster in terms of seismology, meteorology, geology, structural mechanics, etc. But, the invisible damages, such as supply chain network, production system has been obstructed, not revealed. In spite of our experiences in huge disasters, we haven?t tried to unveil these invisible damages. In fact, the automobile industries also suffered a great loss due to this disaster. Supplies of assemblies/products from Japan had stopped, and interrupted other production activities in the world. In order to unveil invisible damages, this paper describes the affects to the supply chain network, production system in Japanese automobile manufacturers by two disasters - the 2011 Tohoku Earthquake and the 2007 Niigata Chuetsu-offshore Earthquake-. In addition, to unveil fundamental issues of their damages, there are the research questions; "Why did automobile manufacturers immediately decide all assembly plants? shutdown", "What?s the difference of the impacts by disaster and depression" and, "Is the limitation of the JIT really exists, or not".
