Reproducing Skilled Operators’ “Master Techniques” with AI and Jointly Verifying Their Effectiveness in the Field
Wevnal Inc. (Head Office: Shibuya-ku, Tokyo; CEO: Hirofumi Isoyama), which operates the BX platform “BOTCHAN,” is pleased to announce that it has begun offering the beta version of its telephone AI agent “BOTCHAN AICALL” in September 2025. This solution automates telephone procedures such as inquiries, cancellations, and changes.
Prior to the official launch of this service, it has been introduced on a trial basis at five companies—Oshima-ya Co., Ltd., Orico Car Life Co., Ltd., Clear Inc. (Men’s Clear), Kenko Kazoku Co., Ltd., NR Co., Ltd., and Yashirobe Gihee Co., Ltd. (listed in Japanese syllabary order, titles omitted). Together with these companies, we are verifying the effectiveness of the service in addressing call center challenges within each company’s operational environment.

Challenges Facing the Call Center Industry
The quality of call center responses is a critical factor that directly affects customer satisfaction, yet much of it depends on the skills of individual, highly experienced operators. Passing on this expertise—knowledge that could be described as the work of a master craftsman—and securing the personnel who can carry it forward have long been major challenges for the industry as a whole.
In fact, according to industry surveys, roughly 30% of call centers record an annual turnover rate of 30% or higher (*1), which is about twice the average for all industries in Japan (*2).
In situations where it is difficult to retain personnel, the more complex the procedures required for telephone support, the greater the burden on operators becomes, and training costs continue to rise.
To address this deep-rooted issue of “personnel dependence,” our company has adopted an approach that clearly differs from simple automation. Specifically, we aim to use AI to replicate the very “master craftsmanship” of top operators, so that anyone, at any time, can receive customer support of the highest quality. It was with this concept in mind that BOTCHAN AICALL was developed.

Comment from Satoshi Asano, Corporate Executive Officer and Senior Managing Executive Officer, General Manager of the Enterprise Services Division and General Manager of the Partner Business Division, Microsoft Japan Co., Ltd.
We sincerely welcome this initiative with wevnal Inc.
While call centers are a critical customer touchpoint, they also involve a high human workload, and for many years a key challenge has been the reliance on a limited number of experienced operators and individual skills, leading to excessive dependence on specific personnel.
By combining Wevnal Inc.’s sophisticated solutions for the e-commerce and retail industries with Microsoft’s cloud technologies, including AI, we expect to be able to contribute to resolving these challenges.
Comment from Kento Kajitani, President of POSTS Inc.
While supporting wevnal Inc. as a consultant, I listened to a demo of the conversational voice for the in-development “BOTCHAN AICALL.” The moment I experienced its remarkably natural conversational quality—far surpassing other Japanese-language voice AI solutions—and its seamless integration with core systems, I became convinced on the spot that it would succeed.
wevnal has exceptional vision and execution capabilities, accurately capturing the major technological wave of AI and creating outstanding products while valuing dialogue with customers above all else. The newly released “BOTCHAN AICALL” is truly a product that embodies and concentrates these aspirations and commitments.
For companies and brands, high-quality customer communication is the lifeline of the business.
"BOTCHAN AICALL" has the potential to deliver a top-tier customer experience, 24 hours a day, 365 days a year, that is virtually indistinguishable from interacting with a human. I am confident it can truly be a "game changer" for many brands and companies. I have high expectations that this product will bring innovation to how Japanese companies and brands communicate with their consumers.
Tomotaka Morikawa, Head of the “BOTCHAN AICALL” Business, wevnal Inc. – Comment
We are greatly honored that, ten months after beginning research and development on BOTCHAN AICALL, leading companies from various industries have chosen to participate.
In call centers, issues such as declining response rates and labor shortages are becoming more serious year by year.
At the same time, the ability of experienced operators to provide customer-centric support is an extremely valuable asset that directly contributes to preventing cancellations and improving customer satisfaction. By reproducing this “craftsmanship” with AI, we aim to transform individualized, person-dependent knowledge into a shared foundation that anyone can leverage.
Through this PoC, we will rigorously verify its effectiveness in an actual business environment and work together to build a framework that enhances the quality of the customer experience, going beyond simple automation.
Looking ahead, we aim to provide companies with customer touchpoints that are reliable 24 hours a day, 365 days a year, and thereby contribute to improving productivity and customer satisfaction across the entire call center industry in Japan.
