Yayoi Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President, Executive Officer & CEO: Kenichiro Muto; hereinafter 'Yayoi') is pleased to announce that the number of registered users*1 for its 'Yayoi Series' business software has surpassed 4 million.
### The Journey of Yayoi
Yayoi is a company that develops, sells, and supports 'Yayoi Series' software to assist back-office operations, with a mission to 'Create a virtuous cycle in Japan by energizing SMEs.' In 1978, when the predecessor of Yayoi was established, accounting work in SMEs was generally done by hand-writing slips and calculating with calculators. Although PCs gradually spread into the business scene in the 1980s, they were expensive and required specialized bookkeeping knowledge, making them out of reach for SMEs.
In 1987, Yayoi launched 'Aoiro Shinkoku Kaikei Yayoi,' the first desktop accounting software designed specifically for SMEs. Since then, the company has consistently launched various services to support the back-office domain of small businesses.
### Background of Surpassing 4 Million Users
The 'Yayoi Series' is approaching its 40th anniversary since its launch. While being cherished by customers as a traditional and reliable software with No.1 sales in business software*2, Yayoi began providing cloud services in 2014. Furthermore, in 2023, it launched the 'Yayoi Next' series as a completely new cloud service, expanding its offerings in line with the trends of the times and technological evolution.
Driven by the desire to be a guidepost for SMEs by providing value half a step ahead, Yayoi offers not only software but also extensive customer support to assist in its utilization. In recent years, in response to major legal reforms such as the Invoice System and the revised Electronic Book Storage Act, Yayoi has not only updated its products but also provided useful information. This attitude of staying close to the reality of SME users has been supported by many, leading to the milestone of 4 million registered users.
### Future Outlook
Yayoi will continue to strive to realize its mission of 'Creating a virtuous cycle in Japan by energizing SMEs.' The company aims for a society where everyone can benefit from technology. Therefore, it will continue to provide both the familiar desktop products for long-time users and cloud services that generously incorporate the latest features including AI, expanding services to meet user needs.
Yayoi aims to revolutionize customer experience and realize operational efficiency and management decision support for all businesses by combining its strengths—'customer base,' 'professional networks,' 'data,' and 'customer support'—accumulated with customers so far, with its original AI technology.

### Comment from Kenichiro Muto, President, Executive Officer & CEO
'As we approach the 40th anniversary of the birth of the Yayoi Series, I am truly honored to have reached the major milestone of 4 million registered users. This is not just a number, but a history of trust built together with the users who love our products and the partners who share our aspirations. I would like to express my heartfelt gratitude once again.
We are now in the midst of a major transformation called Generative AI. While there are voices of anxiety about jobs being taken away, Yayoi aims to stay close to users and provide 'liberation' from the hassle and anxiety of work. On the other hand, we understand that on the actual front lines, there are those who actively embrace technology and those who are hesitant because they are unfamiliar. We will turn the precious voices and data entrusted to us by 4 million people into power and aim for a world where everyone can benefit from the latest technology without even being conscious of it. Yayoi will continue to be the closest companion for SMEs.'
