Thank you for writing to us at Amazon.co.jp.
Unfortunately, "【Amazon.co.jp限定】パシフィック・リム ブルーレイ スチールブック仕様(完全数量限定) [Blu-ray]" isn't currently available for placing an order on our website. However, we'll be happy to let you know when we start accepting orders for it.
We provide the option to sign up for e-mail notification when the item is available. You can see a box labeled "Alert Me" on the product detail page, with a "Sign up" button underneath.
We make this option available only when we believe we'll be able to obtain the item in the future. If we're not sure whether the item will be available, you'll see the message "Currently unavailable. We don't know when or if this item will be back in stock."
I hope this helps. We look forward to seeing you again soon.
Best regards,
K.Yoshida
