Fast Accounting Announces Strategic Collaboration with TKC
Integration of “FAManager” and Accounting AI Agent to Accelerate Compliance with Japan’s New Lease Accounting Standard
TOKYO–Fast Accounting (TOKYO:5588), a company advancing the realization of “Accounting Singularity,” today announced the launch of a strategic collaboration with TKC Corporation.
Through the integration of TKC’s fixed asset management system “FAManager” and Fast Accounting’s proprietary Accounting AI Agent for the new lease accounting standard, the two companies will support mid-sized and large enterprises in Japan in efficiently responding to the new lease accounting requirements, enabling high-speed and high-quality fixed asset management operations.

Strategic Background
Japan’s new lease accounting standard, which will become mandatory for fiscal years beginning in April 2027, requires companies to reassess lease contracts that were previously treated as operating expenses and determine whether they must be recognized on the balance sheet.
This transition is expected to significantly increase operational workload, as companies must:
- Review all relevant lease contracts
- Determine balance sheet recognition requirements
- Manage newly recognized right-of-use assets and lease liabilities
With implementation less than one year away, many enterprises face increasing compliance pressure and resource constraints.
To address these challenges, Fast Accounting has developed the Accounting AI Agent – New Lease Accounting Standard Edition.
Leveraging AI technology trained on more than 200 million processed accounting documents, the system applies optimized judgment logic to automatically determine lease classification, substantially reducing manual workload.
TKC’s FAManager, already adopted by more than 800 companies, has long supported fixed asset management operations. However, the new lease accounting requirements introduce additional complexity, including contract assessment and accounting–tax reconciliation.
This collaboration combines:
- TKC’s extensive client base and accounting domain expertise
- Fast Accounting’s proprietary AI judgment engine
to build a comprehensive solution covering lease classification, asset management, accounting entries, and tax adjustments in an integrated workflow.
Scope of Collaboration
By linking TKC’s FAManager with Fast Accounting’s Accounting AI Agent – New Lease Accounting Standard Edition, the companies aim to deliver enhanced value characterized by Speed × Quality.
Accounting AI Agent Capabilities
- Automated lease classification based on contracts (PDFs, image files, etc.)
- Presentation of decision-support documentation (flowcharts explaining judgment rationale)
- Export of lease asset data compatible with FAManager
FAManager Capabilities under the New Standard
- Centralized management of right-of-use assets and lease liabilities
- Automatic generation of journal entries for accounting system integration

Together, the integrated solution enables end-to-end processing from lease determination to asset registration, accounting system linkage, and tax reporting.
