Service URL: https://www.yayoi-kk.co.jp/products/romusodan-ai/ Background of the Launch In many small and medium-sized enterprises (SMEs), there is no dedicated person in charge of human resources and labor, and it is a reality that business owners, general affairs, or accounting staff handle labor issues while concurrently performing their primary duties. According to a survey conducted by Yayoi*, approximately 85% of the companies have fewer than 50 employees, and furthermore, 61.9% revealed that they do not have a primary person in charge of HR and labor. On the other hand, there is a high need to "check accurate information right now, even if it's not something to consult a corporate labor attorney about." The results also showed that when actual labor-related questions arise, 83.1% rely first on internet searches. However, regarding those search results, 63.2% responded that they "feel anxious about the accuracy of the information," making the balance of convenience and reliability a major issue. Against the backdrop of these challenges, Yayoi will utilize the knowledge and technology of HRbase, which has developed AI solutions specialized in the labor domain, to provide "Yayoi's Anytime Labor Consultation AI," responding to the worries and questions of SMEs' labor operations at any time. By utilizing various data accumulated so far and combining it with technologies such as AI, Yayoi aims to be a presence that illuminates the path for SMEs by providing value looking a half-step ahead. We will continue to support Japanese small businesses and contribute to improving the vitality of the entire Japanese economy. * Questionnaire survey conducted among 880 subscribers of Yayoi Payroll and Yayoi Payroll Next.
