First Accounting Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Keitaro Mori; hereinafter “First Accounting”), a company dedicated to achieving “Accounting Singularity,” and JAPAN BUSINESS SYSTEMS TECHNOLOGY (Headquarters: Torrance, California; President: Kosuke Minaki; hereinafter “JBS USA”), the U.S. subsidiary of Japan Business Systems, Inc., are pleased to announce that they have entered into a partnership agreement.
Through this partnership, the two companies will establish a collaborative framework in which JBS USA, with its extensive experience in implementation and operations in the United States, will bring First Accounting’s AI solutions specialized for accounting operations to the U.S. market.

Background
Since its founding in 2016, First Accounting has been developing and providing AI solutions specifically designed for accounting operations. JBS USA, meanwhile, was established in 1997 and has built a strong reputation as a trusted IT solutions provider, serving numerous Japanese companies operating in the United States.
First Accounting established its U.S. office in 2025. Through this partnership with JBS USA, the company will accelerate its global expansion by collaborating with a partner that has extensive knowledge and experience in both the Japanese and U.S. markets.
Future Outlook
As an initial step, First Accounting and JBS USA will work together to provide implementation support to U.S. subsidiaries of companies that have already adopted First Accounting’s products in Japan.
The partnership will then gradually expand its reach across the broader U.S. market. Through these efforts, First Accounting aims to further strengthen its global sales and delivery capabilities.
Comment from Kosuke Minaki, President of JAPAN BUSINESS SYSTEMS TECHNOLOGY
AI is evolving at a pace beyond what we could have imagined, transforming the very way businesses operate. Since our establishment in 1997, JBS USA has continued to support the digital transformation of numerous Japanese companies operating in the United States.
We see tremendous potential in First Accounting’s solutions. We believe they can play a key role in addressing challenges faced by many Japanese companies, including workforce shortages and rising costs.
Together with President Mori, we look forward to bringing this value to as many Japanese companies as possible and supporting their sustainable growth in the United States.
