Please, don't ruin this by saying wishing wont do anything. This is to show are support to those in need. If you don't want to do this, don't post.
If you have anyone in Japan that you miss, or are worried for, or have lost, for every crane you make an post write their name. <3 You don't have to if you don't want to, but it's nice to show your support to loved ones.
