BestSign Japan, Inc. (Headquarters: Chiyoda-ku, Tokyo; hereinafter 'the Company') has been preparing Japan-focused initiatives under the leadership of Country Manager Tetsuya Koyama, who was appointed in January 2026, to strengthen its business development in the Japanese market.
As part of these related initiatives, the Company is pleased to announce the completion of Japanese UI localization and a website renewal to optimize the user experience (UX), increase utilization, and maximize business outcomes for its e-signature and contract management SaaS in the Japanese market.
■ Country Manager Appointment and Japan Strategy
The Company appointed Mr. Tetsuya Koyama as Country Manager in January 2026 and has since been developing its growth strategy and building an execution framework for the Japanese market.
Mr. Koyama has a track record of success as a sales professional at global IT companies, has served as a sales leader at multiple firms driving business growth, and has experience in global strategy formulation and execution as the APJ (Asia Pacific & Japan) Head of Sales in Singapore for a global IT company focusing on the Microsoft 365 ecosystem.
Most recently, as VP of Sales at a security company, he led the expansion of the Japanese market and has extensive experience in the enterprise market.
Under his leadership, the Company has been steadily preparing its strategy and various initiatives for the Japanese market.
■ UI Localization for Japan
To meet the business requirements of Japanese companies, the following localization measures have been implemented for our intelligent e-signature and contract management platform:
・Optimization of the Japanese UI (adaptation to legal and business terminology)
・Implementation of features based on Japanese business requirements
This will simultaneously achieve efficiency in contract operations for both legal and business departments and strengthen internal controls.
■ Website Renewal
To enhance information provision and acquire potential customers in the Japanese market, the official website has been completely renewed.
・Strengthened content for legal and IT departments
・Expanded application scenarios and solution case studies for Japanese companies
・Optimized pathways for inquiries and free trial sign-ups
■ Background
While the adoption of e-signatures is progressing among Japanese companies, issues such as contract management, internal controls, and audit responses have become apparent.
In particular, companies are demanding higher requirements for integrated functions covering everything from contract creation and execution to storage and analysis, and related needs are evolving from single tools to systematized capabilities.
To meet these needs, the Company is committed to further enhancing its value proposition in the Japanese market.
■ The Value of the BestSign Contract Network and Legal AI
BestSign is not just an e-signature service but a contract execution infrastructure built on the foundation of a company's contractual relationships and authority structure.
During the contract execution process, the platform integrates the corporate entity, signing authority, and internal approval flows into a verifiable and traceable system. This ensures that each contract accurately reflects the company's intent and maintains consistency and control in inter-organizational collaborations.
Furthermore, by embedding Legal AI into the entire contract process on this foundation, contracts evolve from static documents into a data platform linked to business operations. The AI goes beyond understanding contract content and identifying risk clauses; it works in conjunction with the company's actual business processes to analyze contract performance and related business data, supporting advanced risk management and improved operational efficiency.
Moreover, as contract and transaction data are continuously accumulated on the platform, the accuracy and usefulness of the AI will further improve. As the number of user companies expands, the overall value of the platform will increase, and contract operations will evolve from a point tool to an infrastructure.
