Looking at some of the online discussions there seems to be a lot of confusion about this release. Shout! licensed the series from Golden Media Group, an American company that handles licensing deals for companies in Japan. Golden Media was involved in the Americanized KAMEN RIDER DRAGON KNIGHT, the Gamera DVDs from Shout! Factory, and the Gamera and Daimajin Blu-rays from Mill Creek. They are also affiliated with GooHead, the online video service that streams Gamera and Sonny Chiba movies. The company has contributed to a number of articles we've run on SciFi Japan.
Months ago, the owner of Golden Media told me they were negotiating for ULTRA SEVEN with UM Corporation, which is a Japanese company affiliated with the Thai company Chaiyo, who has been in a legal dispute with Tsuburaya Pro over the rights to some of the early Ultra series. The legal battles have been fought in multiple countries with Tsuburaya winning in court... except in Japan. Based on the rulings in the Japanese courts, Golden Media licensed ULTRA SEVEN from UM/Chaiyo.
The good news is that this series will finally get released on DVD and, knowing Shout, they'll do a great job with the materials they were given. The downside is Tsuburaya is not involved, no one who made ULTRA SEVEN is involved, and Shout does not have access to any of the original TPC materials from this show.
I wish this was a fully authorized Tsuburaya release but that won't happen until Chaiyo is defeated in the Japanese courts... orTPC chooses to fight Chaiyo/UM's efforts in the US and deal directly with American distributors themselves.
