Clinic Highlights

Situated in central Tokyo, Nakashima Dental Office in Roppongi, Minato-ku has been resolving the dental troubles of Japanese and foreign patients from over fifty countries for nearly three decades. A member of several U.S. and Japanese dental organizations—including both the American Dental Association and Japan Dental Association —Dr. Kazuya Nakashima is also bilingual, having attended high school and university in the U.S. before earning his dentistry degree from Tohoku Dental University. “I am a comprehensive general practitioner,” says Dr. Nakashima, “which means I provide advanced treatment in cosmetic dentistry, endodontics, periodontics, laser dentistry and adult orthodontics, among other services.” He is well versed in the use of lasers for dental treatment on both soft and hard tissue to kill bacteria, eliminate stains on tooth enamel and eradicate bad breath, and says the latter stays effective for a few months. Dr. Nakashima also does dental implants, and is a certified Gore-Tex bone regeneration specialist. He calls on a talented dental technician in California named Hatada to craft the implants he provides. Dr. Nakashima is a Johns Hopkins private patient referral dentist in Japan. Although he does treat children, he prefers to work on adults. More than half of his patients are foreign, and he welcomes more.
