We were in the Sendai area in October 2007 with our son, his wife and many of her family, their daughter, and my wife's mother. We stayed at the Pension Mirai in Shichigahama.
Much of the Sendai area was beautiful but I assume much of what we saw was destroyed because it was so close to the water. According to Google Earth, the pension was only three meters above sea level, even if the beach was at least a five-minute walk away.
