Patient’s Voice

Dr. Kojima at Tokyo Ambassador Dental Office is a true professional. 
With extensive experience in the US and Japan and bilingual in English and Japanese, the doctor is well-versed in the latest dental developments and explains each procedure in a clear and calm manner. He and is staff are very friendly and put the patient at ease. I highly recommend Dr. Kojima and Tokyo Ambassador Dental Office.

I had the pleasure of meeting Dr.Kojima as a result of my husband's dental emergency, an angry abscessed molar.
Being far removed from the established trust and familiar rapport of your professional circle from home, it can be a daunting task to locate another professional in an environment with cultural and language differences and unnerving when it comes to locating a reputable dentist.

Presently a licensed dental hygienist from Southern California since 1984, registered dental assistant 4 years prior to hygiene, I have had the pleasure to work with dentists from USC and UCLA, graduate specialists in dental specialty fields and Continuing Education directors from accredited dental schools.

Dr. Kojima's unwavering commitment to excellence in dentistry is evident. Not only is he licensed to practice in Japan, he is multi-licensed to practice stateside as well, versed in English and Japanese, and is actively consulting with study groups to keep on the cutting edge of the latest dental technology.  He kindly took the time to consult his circle of dental specialists stateside, utilizing Endodontic Microscopy and Digital Radiography, for an exacting diagnosis which in turn not only afforded peace of mind but saved my husband's molar from extraction.

His kind and efficient ancillary staff utilize state of the art sterilization techniques, so you can rest assured you are in the best of care and in good hands with Dr. Kojima.

One fine day, an orthodontist strongly recommended me visiting Dr. Kojima.
By that time, I had almost finished my orthodontic treatment and asked that doctor what I should do with my remained cavities, and above all, I deadly needed shinning and healthy teeth !His reply was so simple that I should go to see Dr. Kojima at Akasaka Hills Dental Office.

On the first day we met, Dr. Kojima checked the conditions of all my teeth and showed his treatment plan together with cost estimation and time line. All the things were clear to me and I agreed with his reliable plan.

During the several months lasting treatment, we found many of unexpected problems which we could not find on the first day. However, Dr. Kojima and his staff coped with every single problem by providing detailed consultation and best care backed up by the state-of-the-art technology.

Finally, I got back my maximized smile in time for my son’s graduation day and now I recommend my wife to visit Dr. Kojima to regain her big smile!
