Disappearing Posts

I had published 3 posts as well as 2 comments about a week ago, and I just now realized that for some reason they have disappeared from our blog. I just redid the posts (as well as added a few more) so you can view them below, but unfortunately I cannot regain the comments. Sorry to those of you who wrote them. Hopefully this time Blogger won't randomly decide to erase anything! I also just noticed that they put the headers in Japanese. Anyone know why?
