Q. Why did you choose to specialize in residential equipment replacements?

Of the renovation needs, more than 70%* are small-scale renovations costing less than 500,000 yen, such as replacing residential equipment.
On the other hand, for business, the costs associated with on-site estimates outweigh the benefits, making monetization difficult and turning this into an area that no one wants to engage in.
Founded as a plumbing repair company, we experienced industry gaps as we expanded our business to a comprehensive renovation business. We saw the potential of utilizing the Internet to resolve this imbalance.
Therefore, we deliberately chose to focus our service area on the replacement of residential equipment aiming to become a market leader by filling the gap in the industry. This decision marked the beginning of today's "Koukandekirukun."
We aim to transform residential equipment industry, which has often been mocked as complaint-prone industry, into a service that customers can enjoy and trust with confidence.
This vision is built on the belief that both businesses and customers must achieve a true win-win relationship.

  • Individual unit replacement of residential equipment is often avoided by businesses due to the high service costs
  • Pioneer in adopting the Internet in the industry and successfully monetized
  • Aiming to become the market leader in the newly developed residential equipment replacement market
