Active Dermatologist Achieves 85% Private Care Ratio, Systematizes Know-How to Launch Beta Version of 'Moco-style Management OS'

String Inc. (Headquarters: Musashino, Tokyo) officially released the beta version of its management support package for insurance-covered clinics, "Moco-style Management OS", in April 2026. This service is a systematized template collection of the "model for introducing private medical care" built and proven by Dr. Yui Takabatake, an active dermatologist and clinic director, through a 4-year management reform at her inherited clinic (achieving over 3x annual sales and an increase in private care ratio from 4% to 85%). Designed as a lightweight service starting at 30,000 yen per month, it provides a mechanism to directly utilize an active director's management knowledge without requiring heavy initial investments like consulting contracts. The company is recruiting the first 30 doctors as beta founding members.

■ Background: The "Management Wall" Faced by Insurance Clinics

Japanese insurance-covered clinics face structural management challenges:

- Continuous reduction in medical remuneration (effectively a negative trend with revisions every two years)
- Continuous increase in personnel and tenant costs
- Intensifying competition for patients due to an increase in the number of competing clinics

Under these circumstances, many insurance clinics are forced to respond by "increasing the number of patients treated per day," resulting in "the normalization of 3-minute consultations," "staff exhaustion," and "director burnout."

Introducing private medical care is attracting attention as a means to break out of this structure. However, for a clinic primarily based on insurance to fully commit to private care, it requires the systematization of management, such as designing counseling flows, staff education, price design, repeat management (CRM), and visualizing management figures. The reality is that a single doctor lacks both the time and knowledge to tackle this alone.

On the other hand, existing medical management consulting has a high unit price of hundreds of thousands to millions of yen per month, which poses a high barrier to entry, especially for directors of newly inherited or small-scale clinics.

■ What is Moco-style Management OS?

"Moco-style Management OS" is a management support program that systematically installs the mechanisms necessary for insurance clinics to introduce private medical care, divided into three levels:

- Level 1 (Month 1) | Defensive OS: Operational standardization, building the foundation for business efficiency
- Level 2 (Month 2) | Offensive OS: Counseling standardization, CRM, improving closing rates
- Level 3 (Month 3) | Organizational OS: Personnel evaluation, recruitment, management dashboard

[Resources Provided]
- 36+ types of templates and tools (counseling sheets, evaluation system sheets, KPI management tables, etc.)
- Step-by-step SETUP GUIDE (introduction manual for each level)
- Management dashboard (medical receipt integration, automatic KPI aggregation)
- 3 types of members-only Web products (beta founding member privilege)

Everything is provided in a versatile format, originally used in practice by the developer, Dr. Takabatake, at her own clinic, "Moco Skin Clinic Kichijoji Main Branch."

■ Developer: Dr. Yui Takabatake (Director, Moco Skin Clinic Kichijoji Main Branch)

Dr. Takabatake inherited an insurance dermatology clinic in Nishi-Ogikubo, Suginami-ku, Tokyo, in 2022 (at age 29). Before the succession, annual sales were approximately 43 million yen, and the private care ratio was a mere 4%. She started with zero management knowledge.

From there, she gradually introduced private medical care systems, achieving the following results in 4 years:

- Annual sales: Expanded to more than 3x the time of succession
- Private care ratio: 4% -> 85%
- Number of daily consultations: Unchanged since succession (about 40 people)
- Director's working hours: 40 hours/week -> 32 hours/week (20% reduction)
- Overtime hours: Completely eliminated

Notably, she "more than tripled annual sales without increasing the number of daily patients and without falling into a low-margin, high-volume trap." It is a case of realizing "management that increases productivity per hour," which is the exact opposite of "volume-based management."

In 2025, along with business expansion, the clinic also successfully relocated to Kichijoji Honcho. Currently, it operates as "Moco Skin Clinic Kichijoji Main Branch," maintaining a work style of a single doctor system, short consultation hours (10:00-17:30), and zero overtime.

■ Service Features: Providing a "Model" rather than "Consulting"

"Moco-style Management OS" features a lightweight design that sets it apart from traditional medical management consulting.

[Differences from Traditional Consulting]
- Price: Hundreds of thousands to millions of yen/month -> From 30,000 yen/month
- Format: Individual consulting contract -> Template provision format
- Period: 6 months to years -> Minimum 6 months
- Deliverables: Individual customization -> Proven templates
- Target: Medium to large clinics -> Compatible with small and individual clinics

"Moco-style Management OS" specializes in providing a "model" that doctors can introduce at their clinic's own pace. Instead of a heavy consulting contract, it is designed so that a collection of templates proven by an active director at her own clinic can be utilized on a monthly subscription basis.

[Expected Targets]
- Doctors whose main focus is insurance care and who want to start private care
- Clinics that have recently been inherited or opened
- Doctors who want to systematize management but feel consulting is too high a barrier
- Doctors with little experience in private care who want to build case experience

■ Combination with Hands-on Seminars

In parallel with providing the management OS, hands-on seminars for doctors with little experience in private medical care are also held twice a month.

- Botox injection
- Skin development injection hands-on
- Short threads (thread lift)
- Counseling & Assessment
- LP (Landing Page) creation

By supporting both management systems (Moco-style Management OS) and treatment skills (hands-on seminars), the probability of success in introducing private medical care is increased. Seminar information is provided with priority to registered LINE Official Account users.

■ Developer's Comment

When I inherited and opened the insurance dermatology clinic in 2022, I had zero management knowledge and spent my days groping in the dark. Even so, sales gradually grew, and we saw a 'model for introducing private medical care' that produced results while we put it into practice.

I want dermatologists who continue to provide the same insurance treatments to use this model.

And, hoping to improve the industry situation of 'treating over 100 people a day in an assembly-line fashion' even slightly, I packaged it as the Moco-style Management OS.

As a doctor, I hope to spread options in the industry that can balance the quality of medical care with the quality of management.
