Sotas Inc.

Sotas Co., Ltd. (Sotas株式会社) is a Tokyo-based software company building digital infrastructure for the chemical materials industry. Its product line comprises three cloud services: "Sotas化学調査" (Sotas Chemical Survey), which automates applicability/non-applicability determinations and regulatory checks against domestic and overseas chemical regulations, handles SDS creation and version control, chemSHERPA responses, and the request and distribution of documents across the supply chain; "Sotasデータベース" (Sotas Database), a search and comparison platform for chemical materials and companies that also lets customers import their own catalogues and TDS files to build a private cloud database; and "ChemMart" (ケムマート), a service that consolidates supplier information to streamline chemical raw-material procurement and trading.

The company positions its chemical survey tool as reducing survey workload by around 70% without requiring specialist knowledge, and its database as covering roughly 37,000 or more material and company records. Published customer cases include Kubota ChemiX, Koike Sangyo, Koyo Boeki and Shikoku Kako, with reported outcomes such as halving SDS distribution time. Earlier coverage also described a production/process management product, "Sotas工程管理", offering search across 89 types of equipment and 81 resin types and a patent-pending kanban-style board for sharing production line status.

Sotas is governed by representative director Hiroki Yoshimoto, with capital of JPY 60 million, headquarters in Hatchobori, Chuo-ku, Tokyo, and a branch in Hamamatsu, Shizuoka Prefecture. It belongs to industry bodies including JAMP (Article Management Promotion Consortium), the East Japan Plastic Products Industry Association, the Japanese Society for Artificial Intelligence and the Japan Chemical Industry Association for chemical products.
