Comment from Kenzo Hattori, Representative Director of SEVENRICH CAPITAL
I am very pleased to welcome AHS Japan Corporation, a pioneer in infant cranial deformity treatment in Japan, as a new member of the SEVENRICH GROUP.
In my repeated discussions with President Koga, I was very impressed by the company's stance of consistently valuing "trust in customers" and "employee happiness" since its founding. This naturally overlaps with our core value of "making the people involved happy," and I feel great significance in being able to work together.
I decided on this partnership with the hope of contributing to firmly connecting the wonderful organizational culture and world-class technology that President Koga has built to the next generation and expanding them further.
I feel that the strength of AHS Japan Corporation lies in the high-level technology and dedicated attitude of the staff on the ground who sincerely face each infant and their family, in addition to the product power of the world-standard "Starband®." Cranial deformity treatment is a field that affects a child's future and is a business with great social significance. I believe that the track record of spreading such treatments in Japan in cooperation with medical institutions is of great value.
Moving forward, we will firmly support President Koga's vision of a "second founding." As the SEVENRICH GROUP, we will provide support in areas such as marketing, recruitment, organizational development, and IT/DX to create an environment where the staff can focus even more on their services.
As a result, we hope to lead to an expansion of affiliated medical institutions and follow-up facilities, creating a state where information reaches more families.
We believe that M&A is not merely a transfer of capital, but the beginning of a partnership that shares the same aspirations. While respecting the corporate culture and the thoughts of the employees that have been cherished until now, we will combine the power of the group to create new growth together.
We hope to continue working with business owners who are thinking, "I want to take the business to the next level while cherishing its current strengths" and "I want to entrust the next generation to a reliable partner with peace of mind."
Comment from Hidetoshi Koga, Representative Director of AHS Japan Corporation

Through our discussions, I became convinced that they would value our employees and corporate culture, and I felt that with this partner, we could build a solid management foundation where each employee can demonstrate their abilities while spreading our strengths nationwide.
I view this partnership as a "second founding" for our company.
