Located in Shinjuku, Shinjuku Ward, this clinic is a pioneer of Japan's specialized teeth whitening shops that opened in Ginza in May 1995, and will celebrate its 30th anniversary in May 2025. The clinic's whitening has been featured in over 1,000 media outlets, and dental university research has confirmed that it can whiten teeth internally without using ultraviolet rays, with the characteristic that the whiteness lasts long. This technology was developed by NASA scientists and is also recognized for its effectiveness in preventing tooth decay. Recovery whitening is also offered for those who have had whitening before but whose teeth have returned to their original color, and it can be used even if they have received treatment at other clinics. The official website also provides FAQs, information for first-time visitors, and care product information. The medical specialty is dentistry, and English is supported.
