Well, I can only tell what I saw with my own eyes. I went to a town named Tomioka last year to see the newly reopened train station. I think it's about 10 km from Dai-ichi plant. The evacuation order was lifted in March 2017. Anyway, the area around the station, which used to be the downtown, was completely washed away. After cleanup it's now just a giant parking lot as far as eyes can see, except for a few post-tsunami buildings. I walked uphill and there were also many heavily damaged buildings. Even if you can't see the damage, flooding often makes the entire building unsafe due to mold growth or whatever. Some areas might not have been damaged much, but like I said, they depended on infrastructure in the destroyed areas, which is only now being restored.
