Last Modified:2025.03.18

In Japan, the number of elderly single-person households is increasing, and it is predicted that by 2040, 40% of all households will be single-person households. Instead of traditional nursing homes and senior housing with services, "senior citizen shared houses" that allow people to live freely while eliminating loneliness are attracting attention as a new housing option. There are various types of senior citizen shared houses, such as multi-generational coexistence types, types with nursing care, and types where people live together with foreigners, so you can choose one that suits your needs. In this article, we will explain in detail the characteristics, advantages and disadvantages of senior citizen shared houses, how to choose them, and success stories both in Japan and overseas. Consider senior citizen shared houses as a new option for senior life.

What is a shared house for the elderly? Why is it attracting attention?

In recent years, shared houses for the elderly have been attracting attention as a new housing option. Traditionally, nursing homes and senior housing with services were the mainstream housing for the elderly, but shared houses are gaining popularity as an alternative option that can eliminate loneliness through communal living and achieve a more free lifestyle.

Why share houses are attracting attention as a housing option for the elderly

There are several reasons why shared houses for the elderly are gaining attention:

1. Eliminate loneliness
With the increase in single elderly people, more and more people are feeling lonely living alone. In a share house, you can interact with other residents and live a life with a sense of security.

2. Saving on living expenses
Living in a shared house has the advantage of being cheaper than living alone, as rent and utility bills can be shared.

3. Flexible lifestyle
Instead of nursing homes or care facilities, people are looking for an environment where they can receive support while maintaining their freedom of life. In a share house, people can enjoy interacting in a shared space while ensuring privacy in their own rooms.

4. Housing as a preliminary step to nursing care
The idea that shared houses are a suitable option for healthy elderly people who do not yet require nursing care, before moving fully into a facility, is becoming more widespread.

Differences with nursing homes and serviced housing for the elderly (Sakaju)

There are many options for housing for the elderly, including shared housing for the elderly, nursing homes, senior housing with services, group homes, etc. It is important to understand the characteristics of each and choose the housing that is right for you.

First of all, a shared house for the elderly is a form of housing where elderly people or multiple generations live together. There is a high degree of freedom, and although nursing care services are not generally provided, residents can help each other and receive support by using visiting care services. In particular, it is attractive that it eliminates the loneliness of living alone and allows you to live safely while keeping living expenses down.

On the other hand, nursing homes are facilities where care staff are always present and provide daily life support such as meals and bathing. They are for people who require a high level of care, and provide an environment where they can live in peace while receiving support for daily life. However, the disadvantages are that there is little freedom and the rules and schedule of life are fixed.

Serviced senior housing (Sakaju) is basically housing for independent seniors, and offers services such as monitoring and lifestyle consultations. Nursing care services are not generally provided, but by using external nursing care services, it is possible to continue living there even if nursing care becomes necessary. Privacy is easier to ensure than in a shared house for the elderly, but the costs of admission tend to be higher.

Group homes are small-scale communal living facilities for elderly people with dementia. Care staff are always on-site to provide lifestyle support tailored to the symptoms of dementia. Although residents have less freedom, they are provided with an environment where they can receive attentive care.

As such, shared houses for the elderly are attractive because of their high degree of freedom and low cost, making them a good option for people who want to maintain their independence while enjoying interaction with others. They have been gaining attention in recent years as a place to live before the need for nursing care arises.

Increase in single elderly people and social background

The number of elderly people living alone is increasing in Japan, and it is predicted that 40% of all households will be single-person households by 2040. In particular, widows and unmarried elderly people are looking for new housing options.

Additionally, with the number of vacant houses on the rise, 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 houses"

The market for shared housing for seniors is predicted to continue to expand in the future. There are three reasons for this:

1. Increasing participation by local governments and companies
As part of their efforts to support housing for the elderly, local governments and real estate companies are actively developing shared houses, increasing the number of options available.

2. Multigenerational share houses are on the rise
The number of shared houses where young people and the elderly live together is increasing, and a new way of living that encourages intergenerational interaction is becoming more widespread.

3. Introducing overseas success stories
Co-housing for the elderly has been successful in France and Germany, and Japan is also using this model as a reference.

Characteristics and types of share houses for the elderly

A shared house for the elderly is a type of housing where the elderly can live together in peace. Like a regular shared house, it is characterized by the fact that you can utilize the common spaces while ensuring privacy in your own room. In this chapter, we will explain in detail the basic structure of a shared house for the elderly, the difference from living alone, and the main types.

What is a shared house for seniors?

A shared house for the elderly is a type of housing where elderly people can live together in a safe environment. Like a regular shared house, they can use shared spaces such as the kitchen and living room, but still have privacy in their own rooms.

One of the reasons shared houses for seniors are gaining attention is the increase in elderly single-person households. According to a survey by the Ministry of Internal Affairs and Communications, the proportion of single-person households aged 65 or older in Japan is increasing year by year, and it is predicted that by 2040, approximately 40% of all households will be single-person households. Elderly people who live alone are prone to loneliness and health risks, so shared houses are gaining attention as an option to solve these issues.

Main types of share houses for seniors

There are different types of shared houses for seniors depending on the lifestyles of the residents and whether or not they provide support. Below are four major types.

①General share house type
A share house is a place where independent elderly people live together, and the feature is that there are many properties for elderly people who do not require nursing care. The appeal of this style of living is that residents help each other and can enjoy communal meals and recreation.

  • Living expenses can be kept down by sharing rent and utility bills
  • Individual use of visiting care services and day care services
  • Cost range: 50,000 to 150,000 yen per month

2) Multigenerational coexistence (young people x elderly people)
A shared house where young people and the elderly live together, with the aim of promoting intergenerational exchange. In particular, the style of university students and young working people living in the house to provide support for daily life is on the rise. There are already many successful examples in Europe, and the introduction of this style is also progressing in Japan.

<Advantages>
  • Interaction between young people and the elderly has a positive impact on both
  • Elderly people can gain mental vitality through interactions with the younger generation.
  • For young people, the low rent is an advantage.
  • Successful examples include "intergenerational shared houses" in France and Germany.

3) Shared house with care facilities
This is a shared house where nursing care services are provided, and is designed for elderly people who require nursing care. Unlike typical nursing homes, it is characterized by the fact that residents can receive nursing care support while maintaining a more flexible lifestyle.

  • Asian food exchange events are held regularly, allowing you to experience different cultures.
  • Overseas, similar share houses are on the rise in countries such as Spain and Canada.

The pros and cons of share houses for the elderly

Shared houses for seniors are gaining attention as a housing option that can help eliminate the loneliness of living alone and allow people to lead a free life while reducing the financial burden. However, they are not suitable for all seniors, so it is important to understand the advantages and disadvantages depending on their lifestyle and needs. Here, we will explain in detail the advantages and disadvantages of shared houses for seniors.

Benefits of Shared Houses for the Elderly

① Eliminate loneliness and live in a community
There are concerns that elderly people living alone may feel lonely or at increased risk of depression. In a shared house, natural interactions are created through conversations, meals, and recreation in the common areas, making people feel less lonely. In addition, the environment makes it easier for neighboring residents to notice in the event of an emergency, which is also reassuring.

② Living expenses can be reduced
In a share house, rent, utility bills, and food costs can be shared among other residents, so the financial burden is less than living alone. This is particularly appealing for pensioners and seniors living on a limited income, as they can live safely while keeping costs down.

3) You can live there before you need nursing care
Many share houses for the elderly are for seniors who are able to live independently. For those who don't need to live in a nursing home but are worried about living alone, they provide an environment where they can support each other at a reasonable distance. In addition, by combining them with visiting care services, it is possible to continue living there while receiving the support you need.

4. More freedom than a nursing home
In a nursing home, you have to follow the rules of the facility, but in a shared house, you have more freedom and can maintain your own lifestyle, which is a big advantage. You can decide when to go out and eat, so you can live without disrupting your normal daily rhythm.

5. Multigenerational exchange and intercultural experiences
In "multi-generational coexistence share houses" and "international exchange share houses" where people live together with young people and foreigners, it is possible to have exchanges that transcend generations and cultures. In particular, communication with the younger generation is said to be effective in preventing dementia in the elderly.

Disadvantages of Shared Houses for the Elderly

① There are no nursing staff on-site
Unlike nursing homes, shared houses for the elderly do not have care staff on-site 24 hours a day, so if the level of care required increases, it may become difficult to continue living there. It is necessary to check in advance whether visiting care or day care services are available if care becomes necessary.

②Possibility of trouble between tenants
Since share houses involve communal living, problems can arise due to differences in lifestyles and values. In particular, rules about cleaning and meals, and noise issues are likely to arise, so it is important to check the rules and compatibility before moving in.

3) It may be difficult to ensure privacy
Although shared houses provide private rooms, you will share common spaces such as the kitchen, living room, and bathroom with other residents, so it may be difficult to find time to yourself. It is important to consider in advance whether you will be able to live at a comfortable distance from other residents.

④There are still few properties available
Although the number of shared houses for seniors is increasing, the options are still limited compared to regular rental properties and nursing homes. In particular, in rural areas, there are fewer properties and the range of choices is narrow, so it is necessary to do sufficient research in advance.

⑤Barrier-free facilities may be insufficient
Unlike general elderly care facilities, many share houses are renovated from regular homes, so they may not be fully barrier-free. It is especially important to check in advance whether there are stairs or steps in the bathroom, and whether there are handrails.

How to Choose a Share House for the Elderly

Shared houses for the elderly are gaining attention as a new housing option that allows people to maintain freedom while eliminating the anxieties of living alone. However, it is important to choose carefully, as facilities, support systems, and occupancy conditions vary depending on the property.

In this chapter, we will explain in detail what you should check when choosing a share house for seniors and tips to avoid making mistakes. Please use this as a reference to find a share house that suits you.


①Check the location and surrounding environment of the property

When choosing a share house for seniors, the first thing to consider is the location and surrounding environment. Make sure there are facilities nearby that are convenient for daily life.

<Checkpoint>
  • Are there any hospitals or clinics nearby (to feel at ease in case of sudden illness)
  • Are there supermarkets and convenience stores within walking distance (convenient for daily shopping)?
  • Good transport access (easily accessible by bus or train)
  • Is it easy for family members to visit (ease of regular visits)?
As you get older, traveling becomes a burden, so the key is to choose a location that can be completed as much as possible within your living area.

②Check the facilities and layout of the share house

It is also important to make sure that the facilities of the shared house are suitable for the elderly.

<Checkpoint>
  • Is the property barrier-free? (Be careful of properties with many stairs or steps)
  • Are there handrails and elevators (ease of movement)?
  • Whether bathrooms and toilets are shared or private (ensuring privacy)
  • The size and cleanliness of the shared space (is it a comfortable environment?)
  • Security measures (whether or not there is an auto-lock or security camera)
In particular, barrier-free design is a major factor in ensuring that elderly people can live comfortably.

3) Compare contract types and costs

The contract type and costs for shared houses vary depending on the property, so be sure to compare the move-in fees and monthly costs carefully.

<Checkpoint>
  • Initial costs (deposit, key money, security deposit, etc.)
  • Total of monthly rent + common area fee + utility fee
  • Availability of meals and their cost
  • Conditions for moving out (penalties and cancellation procedures)
  • What to do if you need nursing care along the way
It is especially important to check the contract period and moving-out conditions in advance to avoid any problems.

④ Understand the atmosphere and rules of the residents

In a share house, the relationships between residents and the living rules are also important points. Be sure to check in advance so you don't end up regretting it after moving in because it's not the environment you expected.

<Checkpoint>
  • Average age and lifestyle of residents
  • Rules for communal living (meals, cleaning, visitors, curfew, etc.)
  • Relationships with other residents
  • Is there an administrator or manager?
  • What to do when a problem occurs
If possible, we recommend that you do a trial stay beforehand to see the atmosphere.

⑤Nursing care and medical support available

Most share houses are basically for independent elderly people, but some properties may also provide nursing care and medical support. Be sure to check the support system in place with future considerations in mind.

<Checkpoint>
  • Is there nursing staff on-site?
  • Are there any affiliated medical institutions?
  • Can I use visiting care services or day care services?
  • What to do if your health deteriorates (conditions for moving out, etc.)
It is a good idea to check whether you will be able to continue living there even if your level of care needs increases in the future.

⑥ Take advantage of trial stays

It is important to try out a room and see what it's like before you actually move in. Even if it's just for a short period of time, it will be easier to decide if it's right for you.

<Things to check during trial stay>
  • Relationship with residents
  • Meal content and serving method
  • Usability of shared spaces
  • Comfort in everyday life
There are only a limited number of share houses that offer trial stays, so we recommend that you visit in advance if possible to check out the living environment.
