About Diamond Electric


There are three things that will last forever.
Faith, Hope, and Love.
The best of them is Love.
“With warm water instead of cold water
I want to give you a cleaning treatment. “
Bidet Enema, a long-selling diamond electric heat-retaining washer for more than half a century, has the love of its founder.

Diamond Electric has been steadily adhering to the belief that “Everlasting”, which will last forever, will be made for 70 years.
With the “hand skills” of advanced analog (mechanical) engineers who are familiar with “God dwells in the details”, we pay attention to small parts that do not seem to matter at first glance, and all original high performance that can never be achieved with digital technology. We have manufactured and sold “Bide Enema”, an electric heat-retaining washer (Il Rigator) with a built-in bimetal thermostat, polyethylene film heater, and cleaning tube.
With its ultimate human-friendly structure, ease of use, and unparalleled durability (20 years, 30 years, 40 years), Diamond Electric’s “Bidet Enema” is from Hokkaido to Okinawa. , It has been widely used and favored by many hospitals in Japan such as major university medical schools, hospitals attached to medical colleges, national, public and private hospitals, clinics, etc., and has built up a solid track record and trust “Faith” in medical cleaning treatment.

Towards a new era, after-corona:
Now that the medical field is tight and non-face-to-face and non-contact are required, online digital medical care is rapidly becoming widespread.
As a pioneer of medical cleaners, Diamond Electric has been advocating “analog medical care” along with the development of home health care, which is increasingly needed for after-corona, and our product bidet in each home.・ We propose a wide range of utilization of Enema. In particular, the “treatment” for home treatment and care received in the physical space of our home, which we are accustomed to living in, cannot be obtained through information communication using diagnostic software. You can use it to form bonds in various human relationships.
In addition, it is not an advanced digital medical device that requires special technology, but our analog medical device that is easy to use and can be operated by all the families of patients and the elderly, so it is a happy medical treatment for loved ones. It fulfills the warm feelings of the family, “I always want to be close to you” while watching over my life.
Bidet Enema is not only used for such home medical / nursing care cleaning, but also for various purposes in daily life of family members (ex. Pollinosis cleaning, stoma care, colon cleaning, pet care cleaning, etc.) ) Will also be used, and will greatly contribute to lively health and beauty care.
In this way, Diamond Electric has expanded its business domain from domestic medical users to general and diverse users, and also broadly promotes hygiene and health promotion for people overseas, especially in emerging countries in Asia and Africa. With the aim of becoming a company that contributes to (quality of life), Hygienic Wash, which truly loves and protects people’s lives, is the vision and mission of Diamond Electric, “Hope.”
