In recent years, the number of vacant houses has increased and has become a social issue. According to the 2018 Housing and Land Statistical Survey released by the Statistics Bureau of the Ministry of Internal Affairs and Communications, there are approximately 8.49 million vacant houses nationwide, with the vacant house rate reaching a record high of 13.6%. One house is predicted to be vacant. The number of vacant houses in Kanagawa Prefecture is also increasing, and the number of vacant houses is about 480,000 as of 2018, the third largest number in Japan. Above all, the rate of increase in vacant houses (other vacant houses) that have no purpose of use is increasing (*1).
In Chigasaki City, it is known that there are 1,575 vacant houses in the “2019 Chigasaki City Vacant House Survey”, and due to the occurrence of inheritance due to the surplus of housing due to the future population decline and the progress of aging, the number of vacant houses will increase. is expected to increase further. As a countermeasure, based on the “Chigasaki City Vacant House
Countermeasures Plan”, we are promoting efforts for “outbreak prevention”, “appropriate management”, and “utilization” of unoccupied houses.
In the field of demolition work, we operate a comprehensive estimate web service “Crasone” that matches approximately 1,500 specialized construction companies nationwide with owners. We have more than 10,000 construction contracts (*2). From September 2020, we will start offering the “Crasone Peace of Mind Guarantee Pack” (* 3) free of charge, which combines “start money guarantee”, “completion
guarantee”, and “third party liability insurance” for clients and construction companies. We are strengthening our efforts to eliminate the anxiety associated with the demolition of vacant houses and to solve the problem of vacant houses, which has become a social issue. This time, we have concluded an agreement with the aim of contributing to the elimination of vacant houses by collaborating and cooperating to promote the removal of vacant houses while utilizing the resources and features of Chigasaki City and our company. Through these efforts, we will solve the problems of vacant houses, and utilize IT technology and data, such as our “Sumai no Shukatsu Navi”, to improve the quality of the response to residents by local government officials and improve operational efficiency.

■ What is “Sumai no Shukatsu Navi”?
By entering conditions such as the area of the land and building, the nearest station, and the width of the adjacent road from a smartphone, etc., it is possible to easily grasp the approximate amount of the “demolition cost” and the “assessed price of the land after demolition” for free. It can solve the lack of information such as “I don’t know how much the demolition cost will be” and support the decision making of the owner who can’t decide to demolish the vacant house because there is no prospect of selling the land after demolition. In the calculation, regional characteristics such as the dismantling market price and market price in the city are reflected. If you want a specific estimate after understanding the approximate cost, you can also receive an introduction to a construction company through the lump sum estimate service “Krasone”.
In addition, the vacant house countermeasure project that utilizes “Sumai no Shukatsu Navi” has been adopted by the Ministry of Land, Infrastructure, Transport and Tourism in 2022 as the “Model Project for Countermeasures against Empty Houses Utilizing the Housing Market.”
Mr. Hikaru Sato, Mayor of Chigasaki City
Although the city’s population is expected to peak in 2025 and begin to decline, the proportion of elderly people is expected to continue to increase. There are concerns that the surplus of housing and the aging of the population due to the declining population will lead to a further increase in vacant houses.
Vacant houses that are not properly managed are causing great anxiety to the living environment in the surrounding area. We believe that it is important to collaborate and cooperate with organizations. We hope that the conclusion of this partnership agreement will serve as an opportunity to think about how to deal with vacant houses owned by owners, and lead to the appropriate removal of vacant houses. Krasone Co., Ltd. CEO Teppei Kawaguchi
Our company has a vision of “cultivating a ‘city’ recycling culture” and aims to realize a rich life for many people through demolition work. While doing business, I feel that the problem of vacant houses is increasing, and I believe that cooperation between local
governments and private businesses is important for solving this problem.
In preparation for the increase in vacant houses due to the declining birthrate and aging population, we have signed a partnership agreement with Chigasaki City, which is actively working on initiatives, and are very pleased to be able to support community development in the area of demolition of vacant houses. We will do our best to contribute to the realization of community development where citizens can live comfortably and safely by promoting the appropriate removal of vacant houses by utilizing our knowledge, experience and IT technology regarding demolition.

The new service “Crasone”, which was rolled out nationwide in April 2020, is a comprehensive estimate web service that matches
approximately 1,500 specialized construction companies nationwide with owners in the field of demolition work. As a feature, we will introduce excellent recommended construction companies just by entering property information. By directly introducing the
construction company to the client, we can eliminate the multiple subcontracting structure of the construction company and lead to a reduction in construction costs, as well as introducing the optimal construction company according to the client’s desired conditions. The management provides support from consultation on the contents of the estimate to the completion of the construction, and electronic contracts are used for exchanging contracts, so everything can be completed online. Clients can browse the construction company’s reviews and construction results, and by using the “Crasone Peace of Mind Guarantee Pack” (free), which combines a start money guarantee and a completion guarantee, it is possible to carry out construction with peace of mind.
In addition, we also provide a “demolition cost simulator” that allows you to grasp the approximate cost of demolition work in as little as one minute. It has been adopted for two years in a row as a model project for countermeasures against vacant houses that utilizes the housing market. By accelerating the consideration of dismantling vacant houses through this project, we will work to solve the social issue of the ‘vacant house problem’ and promote the ‘end of life’ that has been attracting attention in recent years.
