ASN

What ASN does

株式会社ASN (ASN Co., Ltd.) is a Sendai-headquartered professional services firm that delivers asbestos-related analysis, measurement, consulting, and training across Japan's Tohoku region. Founded on March 15, 2006, the company serves three principal customer segments: construction and demolition companies requiring pre-work asbestos screening, building owners and property managers assessing existing structures, and local government and public-institution clients needing advisory and testing services. The firm positions itself as an integrated "asbestos total solution" provider, with engagements delivered by certified asbestos diagnosticians and mineralogy specialists. Operations are anchored at two Sendai sites: a headquarters at LABO CITY Sendai (Aoba Ward, relocated July 2019) and an analysis laboratory at the 21 Seiki Plaza Research Center (Izumi Ward), both in Miyagi Prefecture.

ASN's analytical core combines X-ray diffraction (XRD) with phase contrast microscopy using a dispersion staining technique compliant with JIS K 3850-1. The platform identifies and quantifies all six regulated asbestos mineral types—chrysotile, amosite, crocidolite, anthophyllite, tremolite, and actinolite—through calibrated reference immersion liquids and formic-acid pretreatment for quantitative work. The methodology was jointly developed with Tohoku University under a NEDO-funded emergency asbestos reduction project, with ASN's chairman Fujimaki Hiromichi serving as Tohoku University Professor Emeritus. Three government designations gate the bulk of ASN's regulated work: an operating environment measurement institution registration (#4-15), a measurement certification business registration for concentration (#147), and a designated investigation organization license under the Soil Contamination Countermeasures Act (#2009-2-2). The firm's product surface also extends into radiation dose measurement (added 2011) and asbestos analysis training courses.

Commercially, ASN runs a sales-led, expert-consultation-driven B2B model with no published rate card. Engagements are quoted on request via phone, fax, or email, with physical sample submission processed through the Sendai analysis laboratory. Revenue is not publicly disclosed, registered capital stands at ¥23,000,000, and the firm is privately held with no parent company, no subsidiaries, and no recorded external funding rounds. The only disclosed operational performance metric is a one-week-or-better analytical turnaround on delivered samples.

Products and services

• Qualitative and Quantitative Asbestos Analysis in Building Materials (建材中アスベストの定性・定量分析) JIS K 3850-1-compliant qualitative and quantitative analysis of asbestos in building materials (spray-applied materials, insulation, and molded boards), using X-ray diffraction combined with phase contrast microscopy and dispersion staining to detect and quantify the six regulated asbestos types (chrysotile, amosite, crocidolite, anthophyllite, tremolite, actinolite). The 0.1 wt% threshold defines 'asbestos-containing' under current law. Targeted at construction and demolition firms required to survey materials before renovation or demolition.
• Asbestos Dust Concentration Measurement (アスベスト粉じん濃度測定) Airborne asbestos fiber concentration measurement at site boundaries and work areas during asbestos-containing material removal or building demolition. Uses membrane filter sampling followed by acetone vapor filter clearing, optional low-temperature ashing, and 400x phase contrast microscopy fiber counting (100 fibers/50 fields for total fibers, 200 fibers/50 fields for asbestos fibers) per JIS K 3850-1. Reports are issued with working environment measurement institution certification. Targeted at construction and demolition firms needing compliance and dust dispersal prevention.
