TOYO Kensa Center Co., Ltd.

TOYO Kensa Center Co., Ltd. is a Japanese testing, inspection and analysis company based in Izunokuni, Shizuoka Prefecture. It operates as a specialist laboratory services provider within the Asahi Kasei Group, offering environmental, industrial and health-related analytical testing to corporate and public-sector clients across Japan. Its official web presence is hosted under the Asahi Kasei domain, reflecting its position as a group company rather than an independent listed entity. The company's service portfolio is broad and technically oriented. On the environmental side it conducts environmental conservation and survey work, water quality analysis, exhaust gas and atmospheric analysis, soil, sediment and waste analysis, work environment measurement, odor measurement, sick-building-related investigation and asbestos measurement. On the industrial materials side it performs testing and analysis of chemical substances and materials, including RoHS-related and ELV-related analysis, BDF-related analysis, hazardous material classification testing, thermal property and calorific value analysis, organic elemental analysis, inorganic element (metal and halogen) analysis, organic analysis and micro-foreign-matter analysis. It also provides health-related testing such as hematological and biochemical testing, drinking water testing, Legionella testing, food poisoning and food-related testing, and Cryptosporidium and Giardia testing. The laboratory has continued to invest in capability and accreditation. It has obtained ISO/IEC 17025 testing laboratory accreditation for halogen analysis compliant with IEC standards, and it has introduced a desktop electron microscope (SEM-EDS) at its Ohito business office. It has also expanded its analytical menu, including new analysis services at its Nobeoka office. Its staff hold recognized qualifications, including labor hygiene consultants (sanitary engineering) and registration on the chemical substance management expert roster maintained by the Japan Association for Working Environment Measurement (JAWE). Regulatory developments shape its business. The company highlights PPWR regulation compliance and heavy metal analysis services, and it notes that 112 substances have been added to the concentration baseline values set by the Minister of Health, Labour and Welfare, and that mask fit testing has been mandatory since 1 April 2024. These themes indicate a positioning around regulatory compliance support for industrial and workplace safety. A significant corporate change occurred on 1 April 2026, when the company changed its trade name to Asahi Kensa Center Co., Ltd. (株式会社旭検査センター). The change aligns the legal and trading name more closely with the Asahi Kasei parent brand. Prior to that, in April 2025, its supervising department changed from the Corporate Planning Department to the Fundamental Technology Research Laboratory. The company remains active and continues to publish news and service updates through its official site.
