Connecting contract management, lease asset management, and business operations—previously fragmented—through AI-based lease classification to provide end-to-end support

TOKYO–Fast Accounting (TOKYO: 5588), headquartered in Minato-ku, Tokyo, and led by Keitaro Mori, President and CEO, announces that its “Accounting AI Agent for the New Lease Accounting Standard,” which it develops and provides with a focus on responses to the new lease accounting standard, will integrate with “ProPlus / ProPlus+” provided by Pro-Ship Inc. (TOKYO: 3763) (headquartered in Chiyoda-ku, Tokyo; President: Motoshi Suzuki; hereinafter “Pro-Ship”), the Operations Center of Deloitte Tohmatsu LLC (headquartered in Chiyoda-ku, Tokyo; Representative Executive Officer): Kenichi Kimura; hereinafter “Deloitte Tohmatsu”), and the electronic contract service “GMO Sign” provided by GMO GlobalSign Holdings K.K. (TOKYO: 3788) (headquartered in Shibuya-ku, Tokyo; President and CEO: Mitsuru Aoyama; hereinafter “GMO GlobalSign HD”).

Under the new lease accounting standard scheduled to take effect in April 2027, almost all lease contracts will be recognized as assets and liabilities on the balance sheet.

As a result, while there are concerns about impacts on financial indicators, accounting departments are also expected to face increased workloads and will need to significantly review operational workflows, including contract management and lease asset management, which is often referred to as part of the so-called “2027 Issue.”

Through this collaboration, Fast Accounting will build an “ecosystem” centered on its AI-based lease classification, connecting contract management, lease asset management, and business operations that are currently fragmented within accounting operations, thereby enabling end-to-end responses and supporting the resolution of practical challenges faced by Japanese companies in complying with the new lease accounting standard.

Ecosystem Concept: Addressing the New Lease Accounting Standard

The essential challenge in responding to the new lease accounting standard lies in “how to apply consistent, continuous, and accurate lease classification to a large volume of contracts and incorporate it into a practical workflow that can be operated in practice.”

To address this challenge, by providing a solution as a “connected framework” that combines the respective strengths of each company—reliable digital management of contracts, integration with lease asset management systems capable of meeting the advanced operational requirements of large enterprises and listed companies, operational design leveraging accounting expertise, and highly accurate lease classification using Fast Accounting’s AI—we believe that we can comprehensively support companies in resolving the practical challenges they face, which has led to this collaboration.

Collaboration Between Our Accounting AI Agent and Each Company

1. Collaboration with Pro-Ship’s Lease Asset Management Solution
Fast Accounting and Pro-Ship are advancing the development of a solution that integrates the accounting AI domain and the fixed asset management domain.1

Through collaboration between Fast Accounting, which possesses advanced technological capabilities in the field of accounting-specialized AI and promotes the “Accounting Singularity Vision,” and Pro-Ship, which aims to provide “the world’s most advanced fixed asset management solution,” the companies aim to significantly reduce the practical operational burden faced by Japanese companies in responding to the new lease accounting standard.

As a first step, toward the new lease accounting standard scheduled to take effect in April 2027, the companies will deploy a joint solution that automates and streamlines the massive amount of contract data entry work and on-balance / off-balance classification operations, while also aiming for business growth through the mutual utilization of their respective customer bases.

In the future, the collaboration will go beyond responding to the new lease accounting standard and will also work toward creating new value through the development of a management platform centered on “physical assets,” linking accounting data with information on on-site assets such as factories and stores.

2. Expanded Collaboration with Deloitte Tohmatsu
Fast Accounting will also begin collaboration with Deloitte Tohmatsu, an existing partner and one of the largest professional firms in Japan, on projects related to responding to the new lease accounting standard.

Deloitte Tohmatsu operates Operations Centers in Maebashi City, Gunma Prefecture, and Sapporo City, Hokkaido, which not only provide Business Process Outsourcing but also promote process transformation of corporate operations.

At these Operations Centers, AI is used for lease classification of each contract; cases that are difficult for AI to determine are reviewed by personnel with accounting expertise, and cases requiring more advanced judgment are handled by certified public accountants. A practical operating model based on a division of roles between AI and humans has been introduced, and the use of this model is expected in this initiative.

3. Business Alliance with GMO GlobalSign HD
Fast Accounting’s Accounting AI Agent will integrate with the electronic contract service “GMO Sign,” which is developed and operated by GMO GlobalSign Holdings K.K.

Through this collaboration, it will become possible to securely manage contracts in digital form, to extract with high accuracy the necessary information such as lease payments and contract periods from contracts, and to automatically determine whether contracts qualify as leases under the new lease accounting standard. This is also expected to contribute to promoting the centralization of contract document data, which had previously been dispersed and managed in a fragmented manner.

By combining the highly secure electronic signature technology used in “GMO Sign” with advanced accounting AI technologies, companies will be able to “automate accounting and asset management through the power of AI while ensuring strict legal requirements,” thereby simultaneously strengthening governance and improving operational efficiency.

“The new lease accounting standard scheduled to take effect in April 2027 will have one of the largest impacts ever on accounting practices at Japanese companies. To overcome this challenge, we will go beyond simply introducing systems and participate in an ‘ecosystem’ that connects the entire process end-to-end—from the digitalization of contract information, to AI-based classification, and ultimately to recording in a robust fixed asset ledger—thereby supporting Japanese companies in responding to the new lease accounting standard,” said Motoshi Suzuki, President and CEO of Pro-Ship Incorporated.

Suzuki added, “Together with Fast Accounting, a pioneer in accounting-specialized AI, and with Deloitte Tohmatsu and GMO GlobalSign Holdings, leading players in their respective fields, we are confident that we can strongly support Japanese companies in strengthening compliance and improving productivity.”

“In Deloitte Tohmatsu’s 2025 Survey on Challenges in Accounting, Finance, and Tax Departments, DX and AI utilization (38.8%) and talent development and recruitment (35.7%) were identified as two of the top challenges. To address these issues, it is important not only to actively adopt digital technologies such as AI, but also to implement frameworks that leverage external expertise,” said Atsushi Iwamura, Representative Executive Officer of Deloitte Tohmatsu.

He added, “By combining Fast Accounting’s advanced accounting-specialized AI technology with Deloitte Tohmatsu’s capabilities in designing and implementing AI strategies, together with our Operations Centers staffed by diverse professional experts, we will provide a new operating model built on the premise of AI.”

“Through ‘GMO Sign,’ we provide digital infrastructure that connects trust between companies. The ecosystem announced today for responding to the new lease accounting standard goes beyond being a simple tool for regulatory compliance and represents a symbolic model case of ‘Accounting Digital Transformation,’ fundamentally transforming the way accounting operations are conducted,” said Yuichi Yamada, Managing Executive Officer of GMO GlobalSign Holdings K.K.

He added, “Automating and advancing accounting and asset management through the power of AI while ensuring strict legal requirements will be a key driver of productivity improvement for Japanese companies. Together with Fast Accounting, Pro-Ship, and Deloitte Tohmatsu, we will fully support companies’ sustainable growth and value creation through this strong partnership.”

“Responding to the new lease accounting standard is not merely a matter of complying with a regulatory change, but an important issue for the accounting and management foundations of Japanese companies. At a time when accounting talent is in short supply across many companies, addressing the new lease accounting standard requires more than standalone AI or standalone systems. It is essential to provide the necessary systems as a ‘connected framework’ that integrates contract management, classification, asset management, and operational processes without fragmentation,” said Keitaro Mori, President and CEO of Fast Accounting.

He added, “The ecosystem concept announced today is precisely aimed at realizing this vision. In addition, compared with conventional system development approaches, it can significantly reduce implementation time and costs. By accumulating operational track records, we also believe it can mitigate one of the common risks associated with system development—that systems do not always function as initially expected. Fast Accounting will continue to contribute to enhancing the corporate value of Japanese companies by integrating our accounting-specialized AI technologies with the strengths of our partners and by building an environment that enables companies to smoothly respond to the new lease accounting standard.”
