The Port of Hachinohe suffered severe damage by the 2011 off Pacific Coast of Tohoku Earthquake Tsunami. To understand the tsunami and its-induced damage, a field survey was conducted. Further, numerical simulations were also carried out to understand propagation and inundation of the tsunami. Results of the field survey and numerical simulations indicated that the tsunami of about 8 m high hit the port, and caused inundation, various debris including shipping containers, destruction of breakwaters and sea-bottom deformation in the port. It seems that the breakwaters and coastal forest contribute to reduction of tsunami impact.
