World-Class Peace of Mind: Japan’s Premium Preventive Medical Care
We work closely with Interpark Kuramochi Internal Medicine Nihonbashi (Nihonbashi, Tokyo), a highly trusted medical institution in Japan equipped with advanced diagnostic facilities. Renowned, widely respected physicians, including leading authorities in preventive medicine Dr. Yasuyuki Yoshizawa and Dr. Jin Kuramochi, will warmly welcome you to provide an exceptional health checkup tailored to your individual needs.
Meet Your Guardians of Health: Japan’s Premier Medical Pioneers

Yasuyuki Yoshizawa,
吉澤 靖之
M.D., Ph.D.
Professor Emeritus & Former President, Tokyo Medical and Dental University (TMDU)
Dr. Yasuyuki Yoshizawa stands at the absolute pinnacle of Japan’s medical elite—a visionary leader whose monumentally transformative hands-on leadership has reshaped the nation’s medical landscape. Serving two distinguished terms (6 years) as the 12th President of Tokyo Medical and Dental University (TMDU), he accomplished the historic feat of securing its status as a “Designated National University Corporation,” an elite title reserved exclusively for institutions capable of world-class research and evolution.
As a world-renowned authority on hypersensitivity pneumonitis and interstitial lung diseases, Dr. Yoshizawa pioneered “Convergence Science”—the groundbreaking fusion of medicine, dentistry, and engineering. This visionary concept laid the literal foundation for the historic merger that created the Institute of Science Tokyo. During the COVID-19 crisis, his decisive leadership swiftly mobilized university hospital resources to save critically ill patients, showcasing his profound, patient-first philosophy.
Yet, what truly elevates Dr. Yoshizawa is his profound humility and compassion. Despite his global stature, he welcomes every patient with the exact same warmth, treating everyone not just as a patient, but as a cherished family member (Ohana). For international patients, his extraordinary expertise combined with his deep, unconditional care offers the ultimate, world-class sanctuary for health and healing.

Jin Kuramochi,
倉持 仁
M.D., Ph.D.
Director, Interpark Kuramochi Clinic of Respiratory Medicine
Dr. Jin Kuramochi stands as a global benchmark of clinical excellence and unwavering medical leadership. A distinguished alumnus of Tokyo Medical and Dental University, he serves as the Director of the Interpark Kuramochi Clinic of Respiratory Medicine, an institution recognized nationwide for its world-class pulmonary and respiratory care.
During the unprecedented global pandemic, Dr. Kuramochi’s clinic became an impregnable fortress of public health. Under his direct, hands-on leadership, the institution examined more than 100,000 patients and managed 800 critical inpatient admissions—spanning a diverse demographic from 3-month-old infants to 93-year-old elderly patients. Remarkably, this massive, high-stakes operation was executed with a monumental record of zero fatalities, a testament to his flawless clinical protocols and profound dedication to human life.
As a leading pioneer in post-viral care, Dr. Kuramochi currently manages the ongoing treatment and rehabilitation of over 900 long-COVID patients. His extraordinary clinical datasets and breakthroughs have garnered profound international acclaim, earned publication in the world’s most prestigious scientific journals, including Nature, and made him a frequent, highly trusted expert on national television. For international patients seeking the absolute pinnacle of safety, precision, and medical expertise in Japan, Dr. Kuramochi represents the ultimate assurance of world-class care.

Kakahiaka’s Exclusive Promise:
Your Two Pillars of Medical Care
The Nihonbashi Wellness Journey goes far beyond a standard medical checkup.
We proudly introduce a dual-layered, world-class medical support system right by your side, linking Japan and Hawaii.

Pillar 1 : Everyday Care in Hawaii
Compassionate Support by Miwako – Registered Nurse in Hawaii
From answering pre-checkup medical questionnaires to follow-up inquiries regarding your digital health reports, Miwako, a licensed professional nurse, is here for you at our local Hawaii window. We eliminate language barriers and post-retreat anxieties, ensuring absolute peace of mind in your everyday life.
A Message from Miwako
“Through my work, I deeply feel that Japanese patients are truly relieved just by having someone who speaks their language and whom they can comfortably confide in. I often hear heartbreaking stories of people who notice symptoms or feel pain but have no one to talk to as their condition worsens. It brings me immense joy when, after speaking on the phone, patients tell me, ‘You have no idea how much this helped me, thank you so much.’”

Pillar 2 : Your Medical Gateway in Japan
Advanced Pharmacological & Preventive Care by
Mr. Sakamoto
坂本 悟
(Pharmacist)
As a leading authority in preventive medicine and a trusted point of contact for pharmaceutical care in Japan, Mr. Sakamoto provides unparalleled guidance. Based on your screening results, he offers expert consultation on your current medications and proposes personalized preventive lifestyle strategies designed to maximize your vitality.
Notably, Mr. Sakamoto shares a deep historical connection with Hawaii. He is the nephew of Kyu Sakamoto, the legendary singer whose timeless masterpiece “Sukiyaki” (Ue o Muite Arukou) remains deeply cherished throughout the Hawaiian Islands. Blending this warm, multigenerational bond with Hawaii and world-class medical expertise, Mr. Sakamoto is ready to support your longevity directly from Japan.
