What JSP does

JSP Corporation is a Tokyo-headquartered, Tokyo Stock Exchange-listed (code 79420) manufacturer of expanded polymer materials founded in 1962. The company produces expanded polypropylene (EPP), expanded polystyrene (EPS), and polyolefin foam products under proprietary brands including ARPRO/P-BLOCK (impact energy management for automotive safety components, HVAC housings, and reusable transport packaging), STYRODIA (thermal insulation with impact absorption for packaging and construction), and FOAMCORE (a process combining expansion and blow molding in a single tool for prefabricated bathrooms and automotive components). JSP also offers sheet and board products (MIRAMAT, CAPLON, P-BOARD, STYRENE PAPER, MIRABOARD, MIRAFOAM) primarily in Japan.

The company operates a B2B enterprise sales model serving five vertical segments — automotive, construction, civil engineering, packaging, and food packaging — through R&D and production facilities in major industrial centers across the Americas, Europe, and Asia, with regional sales offices in the US/Canada, Brazil, Mexico, the UK (EMEA HQ), Japan, China, Korea, Taiwan, India, and Southeast Asia. Mitsubishi Gas Chemical Company holds 47% as principal shareholder, paid-in capital exceeds 10 billion JPY, and JSP holds ISO 14001 certification with TCFD-aligned sustainability governance.

JSP monetizes through hardware sales of both upstream materials (beads for further processing by customers) and finished sheets/boards. Recent strategic activity has centered on European consolidation — full ownership of GHEPI Srl (Italy) and HAPP GmbH (Germany) completed in 2025 — alongside greenfield capacity additions in India and Mexico, the launch of a new business pillar (JSP Advance Solutions) in 2024, and a medium-term growth plan titled 'Change for Growth 2026.' Revenue model is quote-based B2B pricing, not publicly disclosed, consistent with custom-formulation engagement for industrial buyers.
