Prospira Corporation

Prospira Corporation (株式会社プロスパイラ) is a Japanese manufacturer specializing in anti-vibration rubber (防振ゴム) and related industrial rubber products. The company was established in July 2022 as a new operating entity, but it traces its technical lineage to 1937, when the anti-vibration rubber business that Prospira now operates was first started. Over more than eight decades, that business accumulated design, development and production know-how, primarily serving Japanese automobile manufacturers and other domestic customers known for demanding the world's highest standards of performance and quality. Prospira's product portfolio centers on automotive anti-vibration rubber, such as engine mounts, produced through the company's resin and rubber processing technologies. It also supplies industrial anti-vibration rubber with a standard product lineup, air springs (air bellows used in suspension and industrial applications), and pneumatic chucks used in factory automation for gripping, transferring and positioning workpieces. The company emphasizes an integrated system covering purchasing, production and logistics, together with thorough quality control and quality management. Headquartered in Kawasaki, Kanagawa Prefecture, Prospira operates as a group with production bases outside Japan in the United States, China, Thailand and India, and it holds a coordinating function over those group companies. Its corporate philosophy is expressed as contributing to society through the highest quality, and its environmental policy commits the group to reducing environmental impact across the design, development and sale of anti-vibration rubber. As a comparatively small company by headcount, Prospira presents itself as maintaining a fair and open corporate culture that encourages discussion across job levels and responsibilities. The company is led by Representative Director Junya Ono (斧 純也). It publishes statutory financial notices (決算公告) on its website, with notices for its second, third and fourth fiscal terms appearing in 2024, 2025 and 2026 respectively. Prospira remains a private, non-listed company.

The anti-vibration rubber business that Prospira Corporation now operates began in 1937. According to the company, that business spent more than 80 years building experience and know-how while meeting the expectations of Japanese automobile manufacturers and other domestic customers, who are described as having among the world's highest requirements for performance and quality. Through this period the business developed technologies and products that the company now describes as world-top-level, and it cultivated a corporate philosophy of contributing to society through the highest quality. In July 2022, Prospira Corporation was established as a new company to carry this business forward. The company describes the new-company establishment as an opportunity to deliver the various values it can offer to more customers around the world, and it has framed its mission as continuing speedy and dynamic challenges while pursuing its quality philosophy. At the time of its founding, the company already operated as a group with production bases outside Japan in the United States, China, Thailand and India, and it took on a function to coordinate those group companies. Since establishment, Prospira has continued to publish statutory financial notices on its website. Notices for the second, third and fourth fiscal terms were posted in June 2024, May 2025 and April 2026 respectively. The company also registered as a qualified invoice issuing business ahead of Japan's invoice system, which began in October 2023, and it made a donation to the Japanese Red Cross Society in connection with the 2024 Noto Peninsula earthquake. Prospira remains a private company and continues to position itself as a specialist supplier of anti-vibration rubber for automotive and industrial applications.
