For anyone wondering, the copyright owners of Doraemon, the company Shogakukan, have made a claim on my Doraemon video. I have emailed them to ask if there's anything I can do to release the video. If you want to help out, please email Shogakukan to register your support for the video and that you'd like it to go back online. Their email is: info@shogakukan.co.jp
Long live Doraemon!
