Ultra Q (ウルトラQ, Urutora Kyū) is a 1966 Japanese tokusatsu kaiju television series created by Eiji Tsuburaya.

After a survey, the TBS network convinced Tsuburaya Productions to add more giant monsters, as children were intensely interested in them, since Godzilla (Gojira) and Gamera were all the rage at the time (the first "Kaiju Boom" took off after Ultra Q became an enormous hit).

[1] Much like The X-Files, the series features continuing characters who investigate strange supernatural phenomena, including giant monsters, aliens, ghosts, and various other threats.

Tsuburaya provided translated scripts, plus English language opening and closing credits, and a custom, swirling title-card.

At some point, CBS Films backed out of licensing the series, and it was picked up, along with Ultraman, by United Artists Television, producers of The Outer Limits.

[2] In the years following the show's original run, a live action film called Ultra Q The Movie: Legend of the Stars was released in 1990.

[citation needed] In 2013, Tsuburaya Productions and Bandai Visual released the series on Blu-ray, in monochrome and colorized editions.

[3] In 2018, Tsuburaya released four episodes in individual Blu-ray and DVD sets with newly produced special features, as part of their Ultraman Archives project.

Factory announced to have struck a multi-year deal with Alliance Entertainment and Mill Creek, with the blessings of Tsuburaya and Indigo, that granted them the exclusive SVOD and AVOD digital rights to the Ultra series and films (1,100 TV episodes and 20 films) acquired by Mill Creek the previous year.
