ACP Limited Liability Partnership

What ACP Limited Liability Partnership does

ACP Limited Liability Partnership (ACP有限責任事業組合, ACP-LLP) is a Japanese Limited Liability Partnership established on August 13, 2019 and headquartered in Akasaka, Minato-ku, Tokyo. It functions as a consortium structure for small and medium-sized consulting firms and individual IT, management, and operations consultants, addressing the regulatory risk of 偽装請負 (disguised subcontracting) that arises when Japanese SMEs engage as suppliers to major corporations. ACP-LLP centralizes contracts through a secretariat, deploys on-site supervisors to maintain labor compliance, and provides professional liability and cyber insurance to its approximately 16 corporate members, which include ACP Co., Ltd., INTLOOP Inc., and IP Partners Inc.

The organization's core product is ACP-LLP Consulting Services, supplemented by member-exclusive offerings: AI GIJIROKU (AI-powered meeting minutes, launched January 2024), YacLabo (multilingual translation), Dekisugisan (online assistant service), accounts receivable factoring, and an installment capital contribution entry support plan. Revenue is generated through negotiated consulting fees paid by clients and administrative fees paid by member companies to the secretariat. Accenture is identified as the flagship client, recognized as Best Business Partner of the Year 2025, and the organization has formalized a sister LLP (OVIP LLP, launched August 8, 2024) extending the consortium model to bridge-talent engagements.

ACP-LLP holds JIS Q 15001:2023 personal information protection certification, is governed by Representative Director Matsunaga Tetsuhiko, operates exclusively in Japan, and has no public listing or external equity investors disclosed in the input.
