Karuizawa Town's population continues to grow thanks to its easy access from Tokyo and the spread of remote work, with a particularly significant increase since the COVID-19 pandemic, making it one of the towns and villages in Japan with the highest number of in-migration rates. The area is also known as one of the nation's highest-income regions, ranking fifth out of 1,770 municipalities in 2019. In recent years, the influx of wealthy people from urban areas has led to an increase in not only the circulation of used properties, but also expansions, renovations, and new construction. As a result, there has been a significant increase in the need for replacement and renovation of residential equipment.
On the other hand, there are few construction companies and equipment companies that can respond quickly and flexibly to this demand, and we have received feedback from customers who are experiencing inconveniences such as "I can't find someone to ask" or "I can't get a response right away."
Our company's housing equipment DX platform allows you to order online without having to get an on-site estimate, so you can order from anywhere.
Furthermore, as the business grows, we have expanded our construction system nationwide, and currently have a system in place with over 200 "KOUKANSHI"*1 on staff.
This has given us greater flexibility in expanding our area of operation and has also enhanced our shareholder benefits, so we have decided to begin offering services to those living in Karuizawa Town that maintain and improve the comfort and functionality of their homes*2.
*1 "KOUKANSHI" refers to an excellent housing engineer who belongs to or is under contract with KD Service Co., Ltd., a member of the Koukandekirukun group.
