Fukuoka web design and operations firm, a Kaizen Platform subsidiary, with hospital web work
About D-ZERO
D-ZERO Inc. is a web design and production company headquartered in the MG Yakuin Building in Yakuin, Chuo-ku, Fukuoka, with a Tokyo office inside the Kaizen Platform offices in Shirokane, Minato-ku. It was founded on 1 August 2000 and has capital of 45 million yen. Shinya Taniguchi is representative director, and the board includes Shusaku Yano, who led the company in earlier years. In 2021 Kaizen Platform, a Tokyo-listed company, agreed to buy 70.2 percent of D-ZERO, and it is now the main shareholder. At the time of the deal D-ZERO had 54 employees and revenue of 537 million yen for the year to July 2020.
The company plans and builds websites, smartphone sites and apps, campaign sites and landing pages. It also designs interfaces, runs promotion on social networks such as Facebook and X, produces digital signage content and offers website operation support, training and consulting. D-ZERO holds both ISMS information security certification and Privacy Mark certification, which matters to healthcare organisations that handle patient enquiries online. Kaizen Platform bought the firm to add site redesign to its UX improvement services, so D-ZERO projects can now feed into ongoing testing and optimisation.
D-ZERO does not offer a dental service page or dental SEO packages. Its most relevant work is in healthcare. In 2020 it renewed the website of Fukuoka University Hospital, a project of about eight months and roughly 400 pages. The team restructured navigation for patients, families, medical staff and job seekers, added accessibility options such as adjustable text size and background colour, moved visiting hours and access details higher on mobile layouts, and built a photo gallery to ease visitor concerns. Doctors and nurses were consulted alongside the communications team. No traffic or patient metrics were published.
In 2017 D-ZERO signed a business partnership with ASA, a Sendai content producer, to develop a model for creative production in regional cities.
For dentists, D-ZERO fits best as a builder for large dental hospitals, university dental departments, dental schools or multi-clinic groups in Kyushu that need a secure, accessible, content-heavy site and help running it. A single practice looking for local search, Google Maps work and review management would find little in their published offer aimed at that need. Prices and contract terms are not published.
