The Return of Ultraman (帰ってきたウルトラマン Kaettekita Urutoraman? roughly meaning "Ultraman Has Returned") is a tokusatsu SF/kaiju/superhero TV series, and is the 4th Ultra Series. Eiji Tsuburaya had originally intended for the Ultra Series to end with the 1967 series Ultra Seven (Urutora Sebun, 1967), but Ultraman (Urutoraman, 1966) proved to be too popular a character to keep down. After Eiji Tsuburaya's death in 1970, his son Hajime Tsuburaya (who took over Tsuburaya Productions until his own death in 1973) revived the Ultra Series with Return of Ultraman.
