Biene Maja
What is now Nippon Animation is descended from Zuiyo Eizo (Zuiyo Enterprises), an animation studio that produced several popular series in the early and mid-1970s, including 1974's "Heidi, Girl of the Alps", an adaptation of Johanna Spyri's popular children's book "Heidi". The "Heidi" anime was enormously popular in Japan (and later in Europe, and the feature-length edit of the TV series saw a U.S. VHS release in 1985). Zuiyo Eizo soon found itself in financial trouble because of the high production costs of a series (presumably "Maya the Bee") it was attempting to sell to the European market.
