I'm writing this in hope's that you all will find it in your hearts to help! Anything helps!
Though I am not on mainland Japan. I am in Okinawa, Japan which is a small island an hour plane ride to mainland. We were blessed enough not to be hit this time during the 8.9 and so on that mainland was hit by. We did have a few big waves but nothing to be concerned about. Many families have lost loved ones or haven't found them yet. I ask that you pray for them to whomever you pray to and ask that Peace shall get these families through these hard times. I also ask that you pray for our troops who are stationed there or being sent there to help with recovery.
