^ I'm pretty sure that Kamine Park is high enough in the mountains to not worry about the water, Pleasure Garden is probably the one that is most affected on your list, since Hasunuma Kaihin Park is sheltered a bit from the main wave by a peninsula which should have dampened the Tsunami a bit.
But I have a feeling that many of the theme parks in the Tohoku region are closed today to check-ups on the rides for structural damage.
Several train companies had shut down a lot of services yesterday, some have fully reopened, other are running at reduced capacity while others are still closed. Some train company ran all through the night just so that people could get home safely. Where as others were forced to walk home, (one guy trekked for 12 hours to get home...).
