I'm just trying to figure out the release date of a dvd/blu-ray in japan, I tried with the help of rikaikun and google translate to search for the information on the official website and on japanese amazon but wasn't able to find it, hope that someone that actually knows japanese can help me. Thank you in advance if you do, sorry about my request not being as straightforward as a legitimate question about the japanese language, I hope that someone will be kind enough to help still.
