Unfortunately, I don't think so. In my experience, Japan is notorious for never explaining things like this in English. They probably don't expect a target audience to be non-Japanese? What you can do is right click the page, and it might say "Translate to English", and it's not a terrible translation. I'm looking at it right now. Hopefully it will provide sufficient information for you. Beware though, a lot of Japanese websites require a log-in from a Japanese mail.com or at least a gmail. I hope you don't run into that problem.
Actually Dolk provided English pages (Chinese pages as well) for Black Butler character dolls but it seems that they don't do it all the time...I am not sure why, maybe it has something to do with the copyright thing of that particular anime? (for example the publisher of Tokyo Ghoul is unwilling to sell their character doll overseas) I think you can wait for a while and see if they do a international pre-order.
