Features of our health checkups

The physician in charge of comprehensive medical check-ups (ningen dock) holds medical licenses in both Japan and the United States. Examinations and tests are conducted with a thorough understanding of disease susceptibilities specific to Japanese people—which can often be difficult for American physicians to fully grasp.
The physician places a strong emphasis on the early discovery of gastrointestinal diseases, personally performing procedures such as upper endoscopies (stomach cameras) and abdominal ultrasound examinations.
X-ray-related examinations are first interpreted by board-certified radiologists with official U.S. credentials who create formal reports, which are then re-checked at our clinic.
Test results are comprehensively evaluated based on extensive clinical experience as a board-certified internal medicine physician in both Japan and the U.S. The attending physician has spent many years in Japan evaluating ningen dockresults and explaining health check-up findings, and provides detailed reports written in Japanese.
If any abnormalities are found during the check-up, we follow up them by subsequent specialized testing, follow-up observations, and treatment.

Please download the application form and medical questionnaire, fill them out, and bring them with you on the day of your check-up.
We provide a private waiting room exclusively for comprehensive medical check-up (ningen dock) patients, so you can bring your children with you with complete peace of mind. You can enjoy live Japanese television, video games, and more.
We will conduct a medical interview, physical examination, blood draws, and various tests.
For those who undergo an upper endoscopy (stomach camera), we will provide a detailed explanation of the findings while reviewing the recorded footage together.
The total duration is about two hours per person, even with an endoscopy included. If two people are visiting, the entire process will be completed by noon.
Your check-up results will arrive in about two weeks. For those in whom any issues are found, we provide appropriate advice regarding specialized testing and follow-up observations.
The time required for the check-up varies depending on the selected plan. Please feel free to ask if you have any questions or concerns.
