In anger of the reason that the document failed to state clearly and exactly what had been given to Tsuburaya in exchange for these rights, Japanese and Thai courts accepted this contract as real and bonding, because of the supposed hanko of the late Noboru Tsuburaya in the document. Tsuburaya Productions insisted and maintained that the contract was a fraud (due to some errors, including the some titles of the series in the document, such as "Ultra Q" being called ""Ultraman 1: Ultra Q,"" "Ultra Seven" being called ""Ultraman 3: Ultraman Seven,"" and Tsuburaya Productions being called "Tsuburaya Prod. and Enterprises," a name the company never did business under), and repeatedly opposed the issue.
