Chemipro Kasei Kaisha, Ltd.

Chemipro Kasei Kaisha, Ltd. (ケミプロ化成株式会社) is a Japanese specialty chemical manufacturer headquartered in Chuo-ku, Tokyo. The company describes itself as a "technology-development-oriented comprehensive chemical manufacturer" (技術開発型総合化学メーカー) that builds its business on advanced organic synthesis technologies. Its core franchise is ultraviolet (UV) absorbers, where it positions itself as a world-leading manufacturer, and it has extended that synthesis expertise into a broad portfolio of functional chemicals. The company's product range includes UV absorbers, antioxidants, rust preventives, color-developing agents (顕色剤), dye and pigment intermediates, pharmaceutical and agrochemical intermediates, photo-chemical intermediates, and organic electronic materials. In addition to its own branded chemicals, Chemipro Kasei operates a contract synthesis (受託合成) business, leveraging its accumulated synthesis technologies to serve customers in plastics additives, pharmaceutical and agrochemical intermediates, photographic chemicals, and electronic materials. Beyond industrial chemicals, the company operates a "home industry" (ホーム産業) segment focused on termite prevention and extermination agents, along with preservatives, anti-mold agents, and insecticides — developed, manufactured, and sold with a philosophy of being "not bound by wood, but particular about wood." This diversification reflects the company's strategy of applying its core chemical technologies across multiple end markets. Chemipro Kasei is listed on the Tokyo Stock Exchange Standard Market and maintains an active investor relations program, including a third medium-term management plan. Recent corporate news includes a naming-rights agreement for the CAST Advanced Science and Technology Support Center (2025), a partnership-building declaration (2025), and the selection of its perovskite solar cell material development for an AIST (産総研) renewable energy technology commercialization support program (2025). The company also publishes sustainability information and recruitment materials, indicating ongoing operations and growth initiatives.
