Our Philosophy

Welcome to PreBeau Oral Care, an English speaking dental office in Tokyo. We aim to help you maintain your oral health in a great condition. We do not perform unnecessary procedures that may compromise your oral health. We listen to your voice, and customize treatment plans to cater to your dental needs. At our clinic, our core philosophy is centered around the “No-Drill” concept, providing minimally invasive, gentle treatments utilizing the latest global technology and knowledge.

Native-Level English Consultations & Global Standards

Effective dental care starts with clear communication. Our clinical director is a native English speaker who graduated from St. Mary’s International School in Tokyo, followed by a Bachelor of Science at the University of Washington. With extensive postgraduate training in periodontics and implantology at the University of Michigan and UCLA, as well as professional experience as a medical interpreter, you can be assured that language will never be a barrier here.
We explain all diagnoses, treatment options, and costs directly and transparently in English, allowing you to make informed decisions without the need for a third-party translator.
※We provide documentations support for travel insurance holders.

Meet the Director

Dr. Kuniyasu Mori, DDS

Nice to meet you. I am Dr. Kuniyasu Mori, the Director of PreBeau Oral Care.

Background: Advanced Dentistry & Systemic Health

My foundation as a dental professional lies in learning cutting-edge dentistry in both
Japan and the United States.

  • 2005: Graduated from the University of Washington (USA) – Bachelor of Science (B.S.) in Physiology, Minor in Chemistry
  • 2012: Graduated from Osaka University (Japan) – Doctor of Dental Surgery (D.D.S.)
  • 2012–2013: Clinical Resident (General Dentistry & Radiology), Osaka University Dental Hospital
  • 2013: Post-doctoral Scholar in Periodontics, University of Michigan (USA)
  • 2014–2015: ACT Surgical Implant Dentistry Resident, University of California, Los Angeles (UCLA)

When approaching dental care, I always prioritize the perspective of “considering systemic health starting from the oral cavity.” The origin of this philosophy comes from my physiology studies at the University of Washington. By deeply studying how the human body functions and how different organs interact, I became acutely aware of how intimately the oral environment is connected to overall health.
After returning to Japan, I honed my skills at multiple clinics and served as the Director of Kasumigaseki Dental Office starting in November 2022. In May 2026, I proudly opened “PreBeau Oral Care” here in Akasaka, Tokyo.

Message to Our Patients: Protecting Your Mouth and Body with "No-Drill" Care

Throughout my career, I have deeply pursued specialized treatments in implants and periodontics. Through this experience, I strongly realized the paramount importance of prevention—specifically, how to protect and preserve your own natural teeth.
At PreBeau Oral Care, our guiding concept is “No-Drill” dentistry. For example, our Icon treatment, which we heavily focus on, is a highly effective, non-invasive method that improves the appearance of “white spots” without drilling the tooth. As a certified instructor for this treatment, I provide care that maximizes this specialized knowledge.
“No-Drill” dentistry is not just about reducing damage to the teeth. It is the first step in preventive dentistry, and I am convinced that maintaining a healthy oral environment is directly linked to supporting your overall systemic health.
If you are thinking, “I don’t want my teeth drilled,” or “I want minimally invasive treatment that also considers my overall health,” we are here to answer your needs with advanced techniques and rich experience. I look forward to supporting your beautiful smiles and lifelong health right here in Akasaka. Please feel free to consult with us.

Minimally Invasive Dentistry: Moving Beyond Standard Insurance

Many international residents find the Japanese national health insurance system restrictive, often requiring multiple short visits or traditional treatments that involve significant tooth reduction. At PreBeau Oral Care, we operate exclusively as a private, non-insurance-covered clinic to provide uncompromised, high-quality care.
Our core philosophy focuses on minimally invasive, “no-drill” procedures designed to preserve your natural teeth. We specialize in advanced treatments such as DMG Icon resin infiltration for white and brown spots, professional whitening, and metal-free restorations. This allows us to deliver aesthetic, long-lasting results tailored to individual needs rather than standardized insurance protocols.
