What SATO does
SATO社会保険労務士法人 is a licensed Japanese social insurance and labor consulting (社労士) professional services firm headquartered in Sapporo, Hokkaido, operating under the umbrella of SATO INTERNATIONAL GROUP. Founded in 1977 (with the core entity later incorporated) and described as the largest dedicated labor consultant firm in Japan — ranked #1 by office scale for 10 consecutive years — it delivers social insurance and labor administration BPO to 5,600+ client companies through six regional offices (Sapporo, Tokyo, Nagoya, Osaka, Fukuoka, Okinawa) staffed by 940+ specialists. Services span full outsourcing of employment, health, and pension insurance procedures; on-demand spot filings; subsidy and grant application support; local-government-oriented outsourcing; payroll calculation; 36-agreement (overtime labor agreement) reporting; and personal inquiry response. Technology is positioned around information security — EDR + SOC, PrivacyMark, SRPⅡ certification, surveillance, and metal-detector access control — rather than as a SaaS or AI product.
