Small Saitama studio building dental clinic websites with in-house treatment copy and SEO
About 03design (Zerosan)
03design is the web design brand of Zerosan Co., Ltd. (株式会社ゼロサン), a small company registered in Kasumigaseki-higashi, Kawagoe, in Saitama Prefecture just north-west of Tokyo. The company was incorporated in August 2018 with capital of one million yen, but its representative, Hiroto Mikami, has been building websites since 2007. The studio works almost entirely for dental clinics and other medical practices, and is a mobile design office that prefers to stay small and flexible.
Its portfolio counts about 85 projects, of which 63 are general dental clinics and nine are orthodontic practices, with a handful of medical clinics and hospitals. Named dental work includes Suzuki Dental and Orthodontic Clinic in Omiya, Dental Atelier Jiyugaoka, Mirai Dental and Children's Orthodontics in Yamanashi, Morimoto Dental Clinic in Kurume, Apple Dental and Orthodontics Koga EAST in Ibaraki, and a white-spot treatment clinic in Tokyo. Other dental clients include Fukutomi Dental Office, Tatsumidai Kodomo Otona Dental and Yamanaka Dental Clinic.
The process starts with a detailed hearing at the clinic, where the studio asks the dentist about each treatment and then writes the copy itself. A dental hygienist writer is among the freelance roles it recruits, and photos can be taken on site. Pages for self-pay treatments such as implants, orthodontics and cosmetic work get particular attention, and the site keeps reference pages on treatment risks to support compliance with Japan's medical advertising guidelines. Basic on-page and off-page SEO for one area keyword, such as a station name plus dental clinic, is included in a new build, and further SEO advice is sold monthly. The studio does not guarantee rankings and turns away clients who only want rankings or who want to manipulate reviews.
The fee page is unusually open. Original design costs 200,000 yen and a site of up to 15 pages costs 470,000 yen, before tax. A sample new build with five clinic pages and ten treatment pages comes to 602,000 yen including a year of domain and server and the first month of upkeep. Maintenance is 10,000 yen a month for two or three small updates, runs month to month and can be cancelled at any time. Extras include logo design, interview articles, professional photography and listing ads with a three-month minimum.
The studio deals directly with clinics only, refuses subcontracted work from other agencies, and may decline multi-site clinic groups. It is based in the Kanto region but has built sites for clinics in Osaka, Fukuoka, Hiroshima and Shizuoka, with travel billed to the client. Clinic testimonials describe higher search positions and more first-visit patients after launch. Independent practices that want carefully written treatment pages from a one-person-led studio are the clearest fit.
