Little Twins is a short series that was produced ten years ago by Oh Production, the studio that produced Gauche the Cellist ten years before that. Oh Pro was one of the main animation supports of the World Masterpiece Theater for the first few years of its existence, when Takahata and Miyazaki were working there, and then focused on work for Ghibli after T & M made that their base of operations. Between the two they took several years to create their own self-produced Gauche as the studio's calling card.

This series is essentially inspired from the Gnomes world, with little people with pointy hats and realistically portrayed animals. Many of the same staff who were involved in Gauche were involved in this series, including veteran animation director and Oh Pro co-founder Kazuo Komatsubara (Nausicaa, Galaxy Express 999), here the character designer, who helped see the earlier project to completion; and Toshitsugu Saida, Oh Pro's most famous animator, here the animation director, who was the character designer and main animator of the earlier classic. This series shares with Gauche the same soft, etched look and calm, storybook atmosphere. It's one of the studio's most distinctive productions. Numerous interesting figures were involved, including art director Tsuchida Isamu, who was previously involved in another similar show with Komatsubara, Memol in the Pointed Cap; Takashi Nakamura, who animated the op/ed; and Manabu Ohashi, who in the movie provided "special animation" similar in style to that he provided for Junkers Come Here immediately afterwards, plus a nice sequence in the first winter episode. Apparently it was technically a Toei production, because Kimio Yabuki, who thirty years earlier was assistant director on Little Prince & the 8-Headed Dragon, was here as the producer. The movie even boasts a truly spectacular bit of animation at the climax, a strangely out-of-place, ultra-detailed portrayal of a house falling apart, which was probably animated either by the studio's representative, Koichi Murata, or by Masahiro Ando or Shigeto Tsuji, two of the studio's main animators.

There are 3 episodes for each season, plus the movie between summer and fall. The order seems arbitrary: The OVA version started with summer; the rental version started with winter; and the TV broadcast started with spring.
