Crassone, Inc. (Nagoya City, Aichi Prefecture, CEO: Teppei Kawaguchi), which operates the demolition work DX platform "Crassone," has concluded a "Cooperation Agreement on the Promotion of Himeji City Vacant House Countermeasures" with Himeji City, Hyogo Prefecture. As a measure against the vacant house problem, which has become a social issue nationwide, we aim to create a safe and secure city by promoting the removal of vacant houses in Himeji. With this agreement, our company's record of collaboration with local governments reaches 196 municipalities (including government-run organizations), with 17 in Hyogo Prefecture, bringing the population coverage within Hyogo Prefecture to approximately 67% (*1).
Background of the Agreement
In recent years, the increase in vacant houses has become a social issue. According to the Ministry of Internal Affairs and Communications' "2023 Housing and Land Survey" (*2), the number of vacant houses nationwide has reached 9 million, with a vacancy rate of 13.8%, the highest on record. In Hyogo Prefecture, there are 386,900 vacant houses, and the ratio of vacant houses to the total number of households has increased by 0.4 points from the previous survey to 13.8%.
In Himeji City, with its declining population and aging society, the vacant house rate exceeds the national average, making vacant house countermeasures a critical local issue. To address this, the "Himeji City Vacant House Countermeasures Plan" was formulated in fiscal year 2022. It advances measures such as awareness campaigns for owners, promotion of early utilization, and guidance on environmental impacts, based on the fundamental principles of proper management through citizen collaboration, promoting utilization, and preventing the occurrence of specified vacant houses. However, responding to vacant houses with diverse circumstances, such as complex inheritances and aging owners, required detailed support that leverages specialized knowledge and experience in overall vacant house countermeasures, including demolition, in addition to administrative efforts.
Our company operates "Crassone," a service in the demolition construction field that matches clients with over 2,300 specialized construction companies nationwide, with a cumulative total of over 160,000 users to date (*3). Furthermore, our public-private partnership project for vacant house countermeasures, utilizing the "Demolition Cost Simulator" and "Home End-of-Life Navi," was selected for the Ministry of Land, Infrastructure, Transport and Tourism's "Model Project for Vacant House Countermeasures Utilizing the Housing Market" for three consecutive years from fiscal 2021 to 2023. We are currently promoting vacant house countermeasures through public-private partnerships with 196 municipalities nationwide (including Himeji City).
This time, we have concluded a cooperation agreement to solve the vacant house problem within Himeji City by leveraging the respective resources and characteristics of Himeji City and our company, with the aim of preventing and resolving mismanagement and promoting the utilization of vacant houses. Through these efforts, we will not only solve the challenges of vacant houses but also contribute to the promotion of municipal DX, such as improving the quality of resident services and streamlining operations for municipal staff, by utilizing IT technology and data, including our "Home End-of-Life Navi."
Main Initiatives Based on the Agreement
1. Introduction of the "Home End-of-Life Navi," which provides estimated demolition costs and land sale assessment prices.
2. A "Troublesome Vacant House Contact Form" that allows citizens to report problematic vacant houses in their neighborhood to the municipality.
