HRbase Provides OEM Labor Consultation AI to Yayoi: 'Yayoi's Anytime Labor Consultation AI' to Launch for SME Users.

HRbase Co., Ltd. (Headquarters: Chuo-ku, Osaka; CEO: Hiromichi Mita) has announced that its new service 'Yayoi's Anytime Labor Consultation AI,' realized through an OEM provision of its specialized labor AI 'HRbase' to Yayoi Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; CEO: Kenichiro Muto), will be available starting April 23, 2026. This service is a 24/7 labor assistant AI that provides reliable answers based on expert-supervised information regarding legal changes and daily HR/labor inquiries.

### Background of Provision In small and medium-sized enterprises (SMEs), there are often no dedicated HR or labor staff, leaving business owners or general affairs/accounting staff to handle labor issues alongside their primary duties. A survey by Yayoi revealed that approximately 85% of its users are companies with fewer than 50 employees, and 61.9% do not have a dedicated person in charge of HR/labor. While there is a high need for verifying correct information without necessarily consulting a professional labor attorney, 83.1% rely on internet searches first, and 63.2% of them feel anxious about the accuracy of those results. To bridge the gap between convenience and reliability, Yayoi has leveraged HRbase's expertise and technology.

### Key Features of 'Yayoi's Anytime Labor Consultation AI' 1. **Reliable Answers Supervised by Experts:** The generative AI produces answers based on a database of materials supervised by social insurance labor consultants and lawyers, as well as the latest information from public institutions. Each answer includes grounds and sources. 2. **24/7/365 Availability:** Users can consult anytime regarding legal changes, definitions of terms, how to write forms, and procedures for various tasks. 3. **Integration with Yayoi Products:** The AI can explain operation and setting methods for 'Yayoi Payroll Next,' 'Yayoi Attendance Next,' and 'Yayoi Labor Next' from a legal and institutional perspective, fitting seamlessly into the user's workflow. 4. **Continuous Learning Content:** The service regularly distributes articles explaining legal changes and practical tips to help HR staff improve their knowledge.

### Comments from Representatives **Hiromichi Mita, CEO of HRbase:** "By having our technology adopted as an OEM by Yayoi, who has supported Japanese small businesses for many years, we are taking a big step toward making our tech the next business standard. Our goal is to realize a 'Labor Expert AI Agent' that provides value comparable to a dedicated HR staff member within a few years."
