Overview

Knack Productions was a Japanese animation and film production company established in 1967 by a group of former employees of Toei Animation and Mushi Production. The studio was created during a period when Japan's television animation industry was expanding rapidly, and it initially concentrated on producing television series. Its first listed television work was Granny Mischief, which premiered in 1970 and was based on a manga by Machiko Hasegawa, the creator of Sazae-san. During the 1970s and 1980s, Knack developed a substantial catalogue of animated television programs aimed at children and general audiences. Its productions included Astroganger, Chargeman Ken!, Don Chuck Monogatari, Groizer X, The Adventures of the Little Prince, Manga Sarutobi Sasuke, Cybot Robotchi, Manga Mitokomon, and Attacker You!. Several of these titles were distributed outside Japan. Attacker You!, a volleyball drama, gained particularly strong popularity in Italy and France. Manga Sarutobi Sasuke and Cybot Robotchi were also edited and released in the United States as direct-to-video features under the titles Ninja the Wonder Boy and Robby the Rascal. The company was associated with a range of creators and industry figures, including Go Nagai, Ken Ishikawa, Kazuyuki Okasako, Masayuki Kojima, Tetsuro Amino, Shun'ichi Yukimuro, Yoshikata Nitta, and Fumio Ikeno. Its work covered original concepts, adaptations, children's comedy, science fiction, sports drama, and literary or historical subjects. Alongside conventional television production, Knack developed a reputation for producing projects quickly and economically. Critics frequently characterized the studio's animation quality as weak and accused some of its programs of borrowing premises or motifs from more successful properties. That reputation later became part of the reception history of Chargeman Ken!, which was rediscovered online and became an object of ironic appreciation because of its limited production values. In the late 1980s, Knack shifted much of its activity from television animation to original video animation. The company also operated under the Knack+ name for a series of adult-oriented direct-to-video anime releases. These included Ninja Transform Mako-Chan, Bōken Shite mo ii Koro, Yaruki Manman, Dance Till Tomorrow, Mellow, Vixens, Lunatic Night, and Slight Fever Syndrome. The studio's last animation work identified in the reference material was Slight Fever Syndrome in 1997, together with production assistance on Gainax's The End of Evangelion. The company also produced or handled non-animated video projects during this period. From the late 1990s onward, the business moved increasingly toward live-action production. In August 2008, the company formerly known as Knack Productions or Knack changed its name to ICHI Corporation. The rename marked the end of Knack as the company's principal corporate identity, although the earlier name remains associated with its animation catalogue. A 2008 television project, New Attacker You, is listed among the company's animated works despite the long gap after its earlier animation output. Knack Productions is therefore best understood as a historical Japanese studio brand whose principal legacy lies in television animation, international syndication, low-budget direct-to-video work, and the later cult circulation of titles such as Chargeman Ken!.

History

Knack Productions was founded on September 25, 1967, by former personnel from Toei Animation and Osamu Tezuka's Mushi Production. The founding group included illustrator Seiichi Hayashi, animator and director Sadao Tsukioka, former Mushi producer Sakuro Koyanagi, and Seiichi Nishino, who became a principal planner for many of the studio's projects. The company entered the expanding Japanese television-animation market rather than beginning primarily as a theatrical animation producer. Its first identified television production was Granny Mischief, which began airing in 1970 and was adapted from a manga by Machiko Hasegawa. Through the 1970s and 1980s, Knack produced a broad range of series, including superhero and science-fiction programs, children's comedies, literary adaptations, historical adventures, and sports dramas. Important titles included Moonlight Mask, Astroganger, Chargeman Ken!, Don Chuck Monogatari, Groizer X, The Adventures of the Little Prince, Manga Sarutobi Sasuke, Cybot Robotchi, Manga Mitokomon, Psycho Armor Govarian, and Attacker You!. Knack's catalogue was not confined to Japan. Attacker You! became especially successful in Italy and France, where its volleyball theme and television distribution helped it reach a large audience. Two children's comedies, Manga Sarutobi Sasuke and Cybot Robotchi, were edited for American direct-to-video release as Ninja the Wonder Boy and Robby the Rascal. The studio also participated in an American-Japanese coproduction of The Voyages of Doctor Dolittle, which was not broadcast in Japan until 1997. The company worked with several notable manga creators and animation professionals, including Go Nagai and Ken Ishikawa. At the same time, Knack developed a poor critical reputation for inconsistent animation quality and for projects perceived as following the premises of more prominent shows. This criticism did not prevent some of its programs from achieving international exposure or later cult status. Chargeman Ken!, in particular, was rediscovered online many years after its original broadcast. Online audiences treated its technical limitations and unusual presentation as sources of humor and fascination, giving the 1974 series a second life as an internet cult object. In the late 1980s, changing market conditions led Knack to reduce its emphasis on television series and move into original video animation. It released conventional OVAs such as Shibuya Honky Tonk, Korogashi Ryota, Furiten-kun, Osaka Tough Guys, Crows, Grappler Baki: The Ultimate Fighter, and Submarine 707. The company also used the Knack+ label for adult-oriented direct-to-video anime, including Bōken Shite mo ii Koro, Yaruki Manman, Dance Till Tomorrow, Mellow, Vixens, Lunatic Night, and Slight Fever Syndrome. The latter, identified as the company's most recent animation work in the reference material, appeared in 1997. Knack also provided production assistance for Gainax's The End of Evangelion. From the late 1990s, the company concentrated chiefly on live-action production. In August 2008, it changed its corporate name to ICHI Corporation, ending the formal use of Knack Productions as the company's principal name. New Attacker You is listed among the studio's later works in 2008, but the company's best-known historical identity remains tied to its television-animation period and its extensive OVA catalogue.
