The 2011 off the Pacific coast of Tohoku Earthquake of Mw=9.0 with a huge source region of about 500km by 200km caused extensive damage of various structures. Damage caused by tsunami was tremendous and a lot of lives were lost. Besides the damage of concrete structures, seawalls were seriously damaged probably due to scouring. On the other hand some reinforced soil walls were found to be damaged little, though they were inundated with tsunami. Such reinforced soil walls are introduced in this report. One has concrete facing panels and the other tree have metal mesh facing panels. They were not seriously damaged with limited sucking out of backfill owing to vegetation and protection sheet. However, some damage was found at the backfill and facing panels where the soil was not properly covered and protected against erosion.
