JumboKick (ジャンボキック)

JumboKick (ジャンボキック) is an enigmatic electro-mechanical pinball machine of unknown manufacturer and release date. Its existence is known only from two stills in the 1971 Japanese film Zubekô banchō: Zange no neuchi mo nai (Delinquent Girl Boss: Worthless to Confess), which show the backglass and a cabinet front bearing the single-word name 'JumboKick' in large letters. As a sports-themed game centered on kickboxing, it reflects the sport's surging popularity in Japan from the late 1960s through the mid-1970s.

Because only glimpses of the machine survive on film, its actual gameplay features, mechanics, and objectives are unknown. No designer or manufacturer has been identified, and no notable features have been documented.

While its design, art, and full theme details remain unclear, JumboKick's connection to a specific, dateable film appearance gives researchers a rare anchor point for placing it in pinball history, even as most of its story remains a mystery. It stands as an intriguing subject for further research into obscure Japanese amusement machines of the era.
