Dr. Akiko Matsuda
Medical Director, Hada no Clinic Kojimachi
(Kojimachi: Mon, Wed & Thu)
Hello, my name is Dr. Akiko Matsuda.
I began my medical career as a nephrologist. After completing my training at a university hospital, I worked at a general hospital where I cared for patients in the acute, chronic, and dialysis stages of kidney disease. In addition to treating illnesses, I have always valued paying close attention to my patients’ feelings and personal backgrounds, striving to provide care that is compassionate and supportive.
At the same time, as a woman, I found aesthetic dermatology to be a particularly fascinating field. While continuing my work in internal medicine, I also began working part-time in aesthetic dermatology and gradually gained experience. In 2015, I was appointed director of an aesthetic dermatology clinic in Tokyo, marking the beginning of my second career dedicated to the field of aesthetic medicine.
In aesthetic dermatology as well, I place great importance on listening carefully to my patients. By sincerely understanding their concerns and what they hope to achieve, I strive to help brighten the way they see themselves and their daily lives.
Our clinic offers specialized skin-quality treatments focused on acne, along with a full range of advanced medical devices. Although aesthetic medicine has become more accessible today, I understand that visiting a clinic for the first time can feel intimidating. Please feel free to consult us about any concerns, no matter how small.

Dr. Yoko Wakimizu
Medical Director, Hada no Clinic Koenji
(Koenji: Mon, Fri & Sat)
Hello. My name is Dr. Wakimizu, vice director of the clinic.
I entered medical school after graduating from pharmacy school, so I am licensed as both a pharmacist and a physician.
I have a long experience as a cosmetic dermatologist, and in addition to acne and AGA treatment, I have been involved in anti-aging treatments such as treatment with various lasers and injection of hyaluronic acid and Botox.
In recent years, the demand for cosmetic medicine has been increasing for both men and women, and the cosmetic medicine market is rapidly expanding. Medical devices and treatments are evolving daily, and it is believed that they are contributing to the resolution of many people’s skin problems.
However, it cannot be said that patient satisfaction has improved in response to the evolution of cosmetic medicine. This is because, while cosmetic medicine contributes to the resolution of patients’ problems, it is also a business that makes money from patients’ problems.
Some patients may have had the experience of being aggressively recommended expensive surgeries or treatments at beauty clinics. However, I myself am not comfortable recommending unnecessarily expensive cosmetic procedures to my patients and cannot force myself to advertise, etc. I gradually became conflicted about the situation I was in.
Cosmetic practice was interesting and I found it rewarding to be able to solve patients’ problems. However, although I had a passion to study more deeply, I was thinking of stepping back from cosmetic medicine after worrying about various issues.
Just at that time, I had the opportunity to talk to Director Iwahashi of this clinic. Witnessing his sincerity in his practice, his wealth of knowledge, and his insatiable inquisitiveness, I was able to make up my mind to continue practicing cosmetic medicine. I feel that it was a fortunate event that determined my way of life as a doctor.
We are constantly updating our practice by incorporating the latest findings from research and clinical experience into our evidence-based treatments. We do not recommend any treatment forcibly, and we will choose a treatment together with you according to your symptoms.
Because I have suffered through the lights and shadows of cosmetic medicine, I strongly feel the sincerity of our clinic, and I feel a mission to continue this sincere medical system in the future.
It would be my greatest pleasure as a physician if I could support your smile. Please feel free to contact us for consultation as we will make every effort to provide responsible and wholehearted medical care.
As for English, we still have a lot to learn and there are many things that we are not perfect in. We appreciate your understanding.

Dr. Taishi Sakima
(Koenji: Sun & Thu / Kojimachi: Tue, Wed & Sat)
Hello, my name is Dr. Sakima. I have recently joined the HADA NO CLINIC.
I specialize in radiology, with expertise in anatomy, CT, MRI, ultrasound, and image-guided interventional procedures (IVR). I have extensive experience in diagnosing diseases, including cancer, performing catheter-based vascular treatments (excluding the brain and heart), and conducting biopsies on various organs.
For eight years, I served as a medical officer in the Japan Air Self-Defense Force, including two years in a remote island clinic, providing comprehensive care across dermatology and internal medicine. Having struggled with sensitive skin myself, I have always pursued the latest dermatological treatments.
I was drawn to Hada Clinic’s pioneering approach in introducing isotretinoin therapy for severe acne in Japan. I strongly resonate with its commitment to evidence-based, high-quality care in private practice.
I provide personalized treatments for acne and acne scars, including isotretinoin, hormonal therapy, lasers, and subcision. For AGA, I offer standard treatments such as finasteride, dutasteride, and minoxidil. With my expertise in anatomy and percutaneous procedures, I prioritize safety in injectable treatments like Botox and fillers. I also apply my knowledge of radiation physics to ensure safe and effective laser treatments for pigmentation and mole removal.
Beyond our clinic’s treatments, I am happy to advise on other procedures and general medical concerns. Feel free to reach out with any questions.

Dr. Yurie Yamazaki
(Kojimachi: Fri, Sat & Sun)
Hello, my name is Dr. Yurie Yamazaki.
I have worked as a cardiologist, focusing on precise catheter-based procedures, always placing the highest importance on accuracy and patient safety. One of the greatest rewards of my work has been seeing my patients regain their quality of life and watching their expressions and demeanor brighten over time.
I am also deeply drawn to aesthetic medicine because of its potential to improve not only appearance but also overall well-being and quality of life. Through aesthetic treatments, I hope to help patients live richer, more fulfilling lives.
In fact, I personally struggled with acne during my student days. I visited dermatology clinics and tried countless skincare products in search of effective solutions. Because of this experience, I understand how challenging skin concerns can be, and I am committed to offering compassionate care and effective treatments tailored to each individual.
During consultations, I take time to listen carefully to each patient’s concerns and work together to find the best treatment plan. By leveraging my background in internal medicine, I aim to approach aesthetic care from a comprehensive perspective, always staying updated on the latest knowledge and techniques. My goal is to support lasting beauty and health for every patient.
I strive to provide care that makes patients feel, “I’m glad I came here,” and “I want to come back again.” Please feel free to consult me about anything, no matter how small it may seem.

Dr. Nahoko Matsui
(Koenji: Tue & Wed / Kojimachi: Mon)
Hello, my name is Matsui, and I am a physician.
For more than ten years, I have worked as an internal medicine specialist at both university hospitals and community hospitals.
My philosophy as a doctor is: “Treat the person, not just the disease.”
Doctors sometimes become so focused on treating illnesses that we forget to truly see the person in front of us.
When I was younger, I once believed that if the test results improved, the patient must be satisfied as well—only to realize that what the patient truly wanted was something entirely different.
Each patient has their own background, family, work, and personal wishes.
While I always strive to respect those wishes, there are certain limitations within Japan’s public health insurance system.
Due to restrictions such as insurance coverage and patient volume, it is not always possible to fully meet every patient’s expectations, and medical appropriateness does not always align with patient satisfaction.
Skin concerns also vary greatly from person to person.
In particular, acne is something that most Japanese people experience at some point in their lives, and many have likely received insurance-based treatment for it.
However, even when those treatments achieve their intended results, they may not always fulfill every patient’s desired outcome.
At our clinic, acne treatment is provided based on clear medical evidence and a vast number of clinical cases accumulated since our opening, resulting in high patient satisfaction.
In our private (non-insurance) treatments, physicians conduct the counseling sessions directly.
By speaking with each patient personally, I aim to understand their concerns sincerely and work together toward the most suitable treatment.
Please feel free to reach out for a consultation.

Dr. Yosuke Iwahashi
Medical Advisor
(Kojimachi: Sun, Mon & Thu)
Hello, I am Yosuke Iwahashi, founder of Hada no Clinic.
Since opening the clinic in 2015, I have been dedicated to the practice of cosmetic dermatology, with a particular focus on acne treatment. Drawing not only on medical evidence but also on my own experience as a patient, I have always valued providing careful, evidence-based care while remaining closely attuned to each patient’s concerns.
At Hada no Clinic, I have worked with patients facing a wide range of concerns, including severe acne, acne scarring, AGA, pigmentation, dullness, warts, moles, and medical weight-loss treatment. At the same time, I have also been committed to building a strong clinical system and mentoring the next generation of physicians.
Our leadership structure has now evolved, with Dr. Matsuda serving as Director of the Kojimachi Clinic and Dr. Wakumizu serving as Director of the Koenji Clinic. Going forward, in addition to my role as founder, I will continue to support the clinic as a medical advisor, helping to pass on the clinical philosophy and expertise we have developed over the years.
Thank you for your continued trust and support of Hada no Clinic.
From Yosuke Iwahashi, MD
