In Japan, the number of single-person households among the elderly is increasing, and it is predicted that by 2040, 40% of all households will be single-person households. As an alternative to traditional nursing homes and assisted living facilities, "share houses for seniors," which allow seniors to live independently while alleviating loneliness, are gaining attention as a new housing option. Share houses for seniors come in various types, including multi-generational, assisted living, and those shared with foreigners, allowing residents to choose according to their needs. This article provides a detailed explanation of the characteristics, advantages and disadvantages, selection criteria, and successful case studies both domestically and internationally for share houses for seniors. Consider a share house for seniors as a new option for your senior life.
What are shared houses for seniors? The reasons behind their growing popularity.
In recent years, shared housing for seniors has been gaining attention as a new housing option. Traditionally, nursing homes and assisted living facilities for seniors were the main housing options for seniors, but shared housing, which allows residents to alleviate loneliness through communal living and enjoy a more independent lifestyle, is becoming increasingly popular as an alternative.
Why shared housing is gaining attention as a housing option for the elderly
The following factors contribute to the growing interest in shared housing for the elderly:
1. Overcoming loneliness
With the increase in single elderly people, more and more people are experiencing feelings of loneliness from living alone. In a shared house, you can interact with other residents and live a more secure life.
2. Saving on living expenses
In a shared house, rent and utilities are shared, which has the advantage of being more affordable than living alone.
3. Flexible lifestyle
There is a growing demand for environments where people can receive support while maintaining their independence, rather than being confined to nursing homes or care facilities. Share houses offer this option, allowing residents to enjoy socializing in common areas while maintaining privacy in their own rooms.
4. Housing as a preliminary step to long-term care.
The idea that shared housing is a suitable option for healthy elderly people who do not yet require nursing care, as a stepping stone to full-time care, is gaining traction.
Differences from nursing homes and assisted living facilities for seniors.
Housing options for seniors include shared housing, nursing homes, assisted living facilities, and group homes. It's important to understand the characteristics of each and choose the housing that best suits your needs.
First, shared housing for seniors is a type of housing where seniors live together or with people of multiple generations. It offers a high degree of freedom, and while care services are not provided as a general rule, residents can help each other and receive support through visiting care services. In particular, it is attractive because it alleviates the loneliness of living alone and allows for a safe and secure life while keeping living expenses down.
On the other hand, nursing homes are facilities where care staff are always on hand and provide support for daily living, such as meals and bathing. They are designed for people with high care needs and offer a safe and secure environment where residents can live with support for their daily lives. However, a disadvantage is that they offer less freedom and have fixed rules and schedules for daily life.
Service-provided housing for seniors (Sakoju) is basically housing for independent seniors, where residents can receive services such as monitoring and lifestyle consultations. While nursing care services are not provided as a general rule, it is possible to continue living there even if nursing care becomes necessary by utilizing external nursing care services. Compared to shared housing for seniors, it is easier to ensure privacy, but the cost of moving in tends to be higher.
Group homes are small-scale shared living facilities for elderly people with dementia. They have resident care staff who provide support tailored to the symptoms of dementia. While residents may have less freedom, they offer an environment where they can receive attentive care.
Thus, shared housing for seniors is attractive due to its high degree of freedom and low cost, making it a suitable option for those who want to maintain an independent lifestyle while enjoying interaction with others. In recent years, it has been attracting attention as a housing option for those who are not yet in need of care.
The increase in single elderly people and the social background
In Japan, the number of elderly people living alone is increasing, and it is predicted that by 2040, 40% of all households will be single-person households. In particular, there is a need for new housing options for elderly people who have lost their spouse or who never married.
Furthermore, with the increase in vacant houses, local governments and real estate companies are accelerating their efforts to renovate these properties into shared housing for the elderly.
Future market trends for "elderly people x shared housing"
The market for shared housing for the elderly is expected to expand further in the future. The following three points explain why:
1. Increased participation from local governments and companies
As part of housing support for the elderly, local governments and real estate companies are actively developing shared housing, increasing the number of options available.
2. The number of multi-generational shared housing units is increasing.
The number of shared houses where young people and the elderly live together is increasing, and a new way of living that promotes intergenerational interaction is spreading.
3. Introduction of successful overseas practices
Co-housing for the elderly has been successful in France and Germany, and these models are being used as a reference in Japan.
Features and types of shared housing for seniors
Senior-friendly shared housing is a form of housing where seniors can live safely and securely while communally living with others. Similar to typical shared housing, it features the ability to utilize shared spaces while maintaining privacy in private rooms. This chapter will explain in detail the basic structure of senior-friendly shared housing, its differences from living alone, and the main types available.
What is a shared house for seniors?
A shared house for seniors is a type of housing where seniors can live together in a safe and secure environment. Similar to a typical shared house, it allows residents to use shared spaces such as the kitchen and living room, while also ensuring privacy in their private rooms.
One reason why shared housing for the elderly is gaining attention is the increasing number of single-person households among the elderly. According to a survey by the Ministry of Internal Affairs and Communications, the proportion of single-person households among those aged 65 and over is increasing year by year in Japan, and it is predicted that by 2040, approximately 40% of all households will be single-person households. Elderly people living alone are prone to feelings of loneliness and health risks, and shared housing is attracting attention as an option to address these issues.
<Features of shared housing for seniors>
- It can alleviate the loneliness of living alone: Because it's a communal living arrangement, you can interact with other residents on a daily basis, which can reduce feelings of loneliness.
- Savings on living expenses are possible: Since rent and utilities can be shared, the financial burden is reduced compared to living alone.
- You can live a free lifestyle: Unlike nursing homes, there are no strict rules, and you can live a relatively free life.

Main types of shared housing for seniors
There are different types of shared housing for seniors, depending on the residents' lifestyles and the level of support provided. Below are four representative types.
① Typical shared housing type
Share houses are designed for independent seniors living together, and are often characterized by having many properties suitable for seniors who do not require special care.

These are shared houses where young people and the elderly live together, with the aim of fostering intergenerational interaction. In particular, there is a growing trend of university students and young working professionals living on-site and providing support. There are already many successful examples in Europe, and their implementation is progressing in Japan as well.

<Main Features>
- Care staff are on-site or make regular visits.

Advantages and disadvantages of shared housing for seniors
Shared housing for seniors is gaining attention as a housing option that can alleviate the loneliness of living alone and allow for a more independent lifestyle while reducing financial burdens. However, it is not suitable for all seniors, and it is important to understand the advantages and disadvantages depending on their lifestyle and needs. Here, we will explain the advantages and disadvantages of shared housing for seniors in detail.
Benefits of shared housing for seniors
① To alleviate loneliness and enable living within a community
For elderly people living alone, there are concerns about increased feelings of loneliness and depression. In a shared house, natural interaction occurs through conversations, meals, and recreation in common spaces, making it less likely to feel lonely. In addition, the environment where neighbors can easily notice in emergencies provides peace of mind.
② You can reduce living expenses.
In a shared house, residents can share rent, utilities, and food expenses, making it more economical than living alone. This is especially appealing to pensioners and elderly people with limited incomes, as it allows them to live comfortably and securely while keeping costs down.
③ You can live there before you need care.
Most shared housing for seniors is designed for seniors who can live independently. It provides an environment where people who don't need to move into a nursing home but feel uneasy living alone can receive support from others at a comfortable distance. Furthermore, by using home care services in conjunction with the shared housing, it's possible to continue living there while receiving the necessary support.
④ Offers more freedom than nursing homes
While nursing homes require residents to follow the facility's rules, shared housing offers a high degree of freedom, allowing residents to maintain their own lifestyle, which is a major advantage. The ability to decide on outings and meal times allows residents to continue living without disrupting their previous daily routines, which is a significant benefit.
⑤ Opportunities for intergenerational exchange and cross-cultural experiences
In "multi-generational co-living share houses" and "international exchange share houses" where residents live together with young people and foreigners, interaction across generations and cultures is possible. In particular, communication with younger generations is said to be effective in preventing dementia in the elderly.
Disadvantages of shared housing for the elderly
① Care staff are not always on-site.
Unlike nursing homes, shared housing for seniors does not have 24-hour care staff on-site, so it may become difficult to continue living there if your care needs increase. It is necessary to check in advance whether home care or day services are available if you require care.
② Potential for disputes between residents
Because shared housing involves communal living, problems can arise due to differences in lifestyle and values. In particular, issues such as rules regarding cleaning and meals, and noise problems are common, so it is important to check the rules and compatibility before moving in.
③ In some cases, it may be difficult to ensure privacy.
While private rooms are provided in shared housing, residents share common spaces such as the kitchen, living room, and bathroom, making it difficult to have time alone. It's necessary to consider in advance whether you can live comfortably with other residents.
④ There are still few properties available.
While the number of shared housing options for seniors is increasing, the choices are still limited compared to typical rental properties and nursing homes. In particular, the number of properties is small in rural areas, limiting the range of choices, so thorough research is necessary beforehand.
⑤ Accessibility facilities may be insufficient.
Unlike typical senior living facilities, many shared houses are converted private homes, and therefore may not be fully accessible. It is especially important to check in advance for things like stairs, bathroom steps, and the presence of handrails.
How to choose a shared house for seniors
Shared housing for seniors is gaining attention as a new housing option that allows them to maintain their independence while alleviating the anxieties of living alone. However, since facilities, support systems, and entry requirements vary from property to property, it is important to choose carefully.
This chapter provides a detailed explanation of key points to consider when choosing a shared house for seniors, as well as tips to avoid common mistakes. Please use this as a reference to find a shared house that suits you.

① Check the property's location and surrounding environment.
When choosing a shared house for seniors, the most important factor is the location and surrounding environment. Make sure there are convenient facilities nearby for daily life.
<Checkpoints>
- Is there a hospital or clinic nearby? (For peace of mind in case of sudden illness)
- Are there supermarkets and convenience stores within walking distance? (Convenient for daily shopping)
- Good access to public transportation (ease of using buses and trains)
- How easy is it for family members to visit (ease of regular visits)?
As people get older, traveling becomes a burden, so it's important to choose a location where you can complete as many daily tasks as possible within your living area.
② Check the facilities and floor plan of the shared house.
It's also important to carefully check whether the facilities in a shared house are suitable for elderly people.
<Checkpoints>
- Is it designed to be barrier-free? (Be cautious of properties with many stairs or steps.)
- Are there handrails or elevators? (Ease of movement)
- Are bathrooms and toilets shared or individual (ensuring privacy)?
- The size and cleanliness of shared spaces (whether it's a comfortable environment)
- Security measures (presence or absence of automatic locks and security cameras)
In particular, whether or not a design is barrier-free is a major factor in ensuring a comfortable living environment for the elderly.
③ Compare contract types and costs.
Since the contract terms and costs for shared housing vary depending on the property, be sure to carefully compare the move-in costs and monthly fees.
<Checkpoints>
- Initial costs (security deposit, key money, guarantee deposit, etc.)
- Total of monthly rent + common area maintenance fee + utilities
- Whether or not meals are provided and the cost
- Conditions upon moving out (penalties and cancellation procedures)
- How to handle situations where caregiving becomes necessary during the course of treatment
In particular, it is important to check the contract period and move-out conditions in advance to avoid problems.
④ Understand the atmosphere and rules of the residents.
In a shared house, the relationships between residents and the rules of daily life are also important factors. To avoid regretting your decision after moving in because "the environment wasn't what I expected," be sure to check these things beforehand.
<Checkpoints>
- Average age and lifestyle of residents
- Rules for communal living (meals, cleaning, visitors, curfew, etc.)
- Compatibility with other residents
- Is there an administrator or manager?
- How to handle problems when they occur
If possible, it's recommended to do a trial stay beforehand to get a feel for the atmosphere.
⑤ Availability of care and medical support
While most shared housing is primarily for independent seniors, some properties may offer care and medical support. It's a good idea to check the support system in place, considering your future needs.
<Checkpoints>
- Are care staff always on-site?
- Are there any affiliated medical institutions?
- Can I use home care and day care services?
- What to do if your health deteriorates (conditions for moving out, etc.)
It's reassuring to check whether you'll be able to continue living there even if your level of care needs increases in the future.
⑥ Utilize trial stays
It's important to try living there for a short period to get a feel for the place before actually moving in. Even a short stay will make it easier to determine if it's a good fit for you.
<Things to check during a trial stay>
- Compatibility with residents
- Contents and methods of serving meals
- Ease of use of shared spaces
- Comfort in everyday life
While only a limited number of share houses offer trial stays, it's highly recommended to visit beforehand and check the living environment.
