Renting an apartment in Osaka as a single foreigner is already more complex than most people expect. Add a partner, a spouse, or children to the equation, and a new layer of questions emerges — questions that most rental guides don't address and that the listings certainly don't answer. Whose name goes on the lease? Does both partners' income count toward eligibility? What happens if one of you doesn't have Japanese residency yet? How do you find something large enough, in the right neighborhood, at a price that works — when the foreigner-friendly market is already constrained?
This article addresses the specific realities of renting in Osaka as a couple or family unit. It covers the documentation, the income assessment, the size and neighborhood considerations, the questions about unmarried and same-sex couples, and what to expect when children are part of the picture. If you're moving to Osaka with someone else, this is the article that explains what's different about your search.

In Japan's rental system, the lease has a named primary tenant (keiyaku sha) — the person legally responsible for the rental obligation. This is not a formality. The primary tenant is the person whose income is assessed, whose visa status is evaluated, whose guarantor arrangement is established, and who bears legal liability if rent is unpaid or the apartment is damaged. Choosing which partner becomes the primary tenant is the first and most consequential decision a couple faces in the Osaka rental process.
The practical answer is straightforward: the primary tenant should be the partner whose profile is strongest by the criteria the management company will apply. This typically means the partner with the most stable, documented income in Japan, the most favorable visa category, and the longest residency history. If one partner has permanent residency and the other is on a newly issued work visa, the PR holder should almost certainly be the primary tenant regardless of whose idea the apartment was.
For couples where both partners are foreign nationals with equivalent profiles, the choice matters less — but should still be made deliberately, with the guarantor company's acceptance criteria in mind. Some guarantor companies have specific requirements about the relationship between primary tenant and co-habitant that affect which partner's documentation needs to be primary.
Japan's rental system generally requires landlords and management companies to be informed of everyone who will live in the apartment — not just the primary tenant. This is typically handled through a co-habitant declaration (dokyonin todoke) at the time of application, listing the names, ages, and relationships of all occupants. A couple moving in together will both appear on this declaration, even if only one is the primary lease-holder.
The declaration matters because it gives the landlord a complete picture of who is living in the property. Bringing a partner to live in an apartment that was applied for and approved as a single-occupant unit — without disclosing the co-habitant — is a lease violation. This is a situation that arises more often than it should, usually not from bad faith but from not understanding that the occupancy declaration is a formal requirement rather than optional background information.
One of the most common questions couples ask when searching for an Osaka apartment is whether both incomes will be considered together for eligibility — effectively doubling their assessed income and opening up a wider range of properties. The answer is: sometimes, and with significant variation depending on the management company.
Japan's rental income assessment rule of thumb — monthly rent should not exceed one-third of monthly income — is typically applied to the primary tenant's income only, not the household combined income. This is the default position of most management companies and guarantor companies. The logic is that the legal rental obligation rests with the primary tenant, and their income is the relevant measure of their capacity to meet it.
In practice, this means that a couple where Partner A earns ¥350,000/month and Partner B earns ¥280,000/month cannot automatically present a combined ¥630,000 income for the purpose of qualifying for a ¥200,000/month apartment. Partner A's income alone — the primary tenant's — is assessed against the rent level, and ¥350,000 would typically qualify for a rent of up to approximately ¥115,000 under the standard formula.
Some management companies — particularly those operating newer buildings or those specifically targeting family households — will consider combined household income when both partners have documented, stable income. This is more likely when both partners are salaried employees with employment certificates, when the income documentation is clear and consistent, and when the application is presented in a way that explicitly addresses the household income picture.
This is a situation where application presentation matters enormously. A management company that might default to single-income assessment can be persuaded to consider combined income when the case is made clearly and the documentation supports it. An experienced agent who knows how to structure this presentation — and which management companies are open to it — can meaningfully expand the range of properties available to a couple who would otherwise be limited by single-income assessment.
Guarantor companies have their own income assessment criteria, which are separate from and sometimes more conservative than the management company's. Even if the management company accepts a combined income presentation, the guarantor company may not. Knowing which guarantor companies will approve a couple's application — based on their specific visa types, income levels, and employment situations — is the kind of background knowledge that shapes the search strategy before a single application is submitted. Our article on guarantor companies in Japan explains how the assessment process works in detail.
This is an area where expectations and reality diverge significantly, and where honest information matters more than reassuring generalities.
Japan does not have a legal framework for de facto partnerships equivalent to those in many Western countries. From a rental application perspective, an unmarried couple is two individuals with no formal legal relationship — which means the co-habitant declaration will show a relationship category that some older or more conservative landlords may question.
In practice, the Osaka rental market has become substantially more pragmatic about unmarried couples over the past decade. Younger landlords, professionally managed buildings, and management companies operating in internationally oriented neighborhoods rarely raise this as an issue. The application is processed with both occupants declared, the co-habitant's income may or may not be considered, and the tenancy proceeds without drama.
Where friction arises is with older private landlords — typically individuals rather than professional management companies — who retain more traditional views about household composition. These landlords are less likely to be operating in the neighborhoods most foreign renters target, but they exist and occasionally appear in listings that look attractive on paper. An agent with local knowledge can usually identify them before the application stage.
Japan has no national legal recognition of same-sex partnerships, though several municipalities — including Osaka — have introduced partnership certificates (partnership seido) that provide some local administrative recognition. Osaka City's partnership certificate has been available since 2019 and can be used to demonstrate the relationship in certain administrative contexts.
For rental applications, the practical situation mirrors that of unmarried couples with an additional layer of variability. The majority of professional management companies in Osaka do not explicitly discriminate on the basis of relationship type, and the occupant declaration simply lists two adults sharing an apartment. But informal gatekeeping exists, and the outcome can depend on the specific landlord, the management company, and how the application is framed.
Working with an agent who is familiar with which buildings and management companies have genuinely neutral policies — rather than discovering the issue at the rejection stage — is the most practical protection for same-sex couples navigating the Osaka rental market.
A common scenario for international couples moving to Osaka: one partner has a work visa and has already established residency, while the other is arriving on a dependent visa, is still waiting for visa approval, or is joining later. This asymmetry in residency status creates specific complications in the rental application that need to be anticipated and managed.
A partner on a dependent visa (kazoku taizai) has legal residency in Japan but typically has no independent income — the visa is issued on the basis of the primary visa holder's status and finances. For rental purposes, the dependent visa holder generally cannot contribute meaningfully to the income assessment. The application effectively rests on the working partner's profile alone, which may limit the accessible price range depending on their income level.
The dependent visa itself is not a problem for landlords — it is a legitimate long-term residency status and is recognized as such. The limitation is purely financial: the household's qualifying income for rental purposes is the working partner's income only, regardless of any overseas income or assets the dependent visa holder may have.
In some cases, one partner needs to secure housing before the other arrives — either because of a tight work relocation timeline or because visa processing means one partner arrives later. Applying for and signing a lease on behalf of a two-person household when the second occupant isn't yet in Japan is possible but requires clear communication with the management company about the timeline and the intended occupancy.
Some landlords and management companies are comfortable with this — particularly if the arriving partner's visa status and timeline are clearly documented. Others prefer all occupants to be present and verified before the lease is signed. Knowing in advance which approach a given management company takes saves the embarrassment of raising this issue at the wrong stage of the application process.
The Japanese apartment size taxonomy — 1R, 1K, 1LDK, 2LDK, 3LDK — maps imperfectly onto the space requirements of foreign couples and families, who often come from countries where living standards per capita are larger than Japan's urban norm. Understanding what each category actually provides helps calibrate expectations before the search begins.
A 1LDK (one bedroom plus a living/dining/kitchen space, typically 35–55㎡) is the practical minimum for most foreign couples who want a genuine separation between sleeping and living spaces. At the lower end of this range — 35–40㎡ — it is compact but functional. At 50–55㎡, it feels spacious by urban Japanese standards. The 1LDK category is the most competitive in the foreigner market and the one where good properties in accessible neighborhoods move quickly.
Couples who both work from home, or who have significant possessions, will find a 1LDK constraining over time and often end up searching for 2LDK after six to twelve months. If your budget allows, targeting 2LDK from the outset — even for two people — is worth serious consideration. The additional space compounds in daily quality of life over a two-year tenancy.
A 2LDK (typically 55–75㎡) is the standard starting point for a family with one child, providing a separate bedroom for the couple and a room that can function as a child's bedroom or family room. For two children at different life stages, a 3LDK becomes the more practical configuration — though supply of 3LDK apartments in central Osaka that are both foreigner-accessible and reasonably priced is limited, and the search typically takes longer.
It is worth noting that Japanese families often use living spaces differently from Western families — rooms serve multiple functions, and what appears to be a small footprint on paper can feel more liveable once furniture is in place and the spatial logic of the apartment is understood. Viewing properties rather than filtering by square metre alone produces better outcomes.

Children add another variable to an already complex application process. The good news is that families with children are generally viewed more favorably by Japanese landlords than single foreign applicants — a family signals stability, longer-term tenancy intentions, and lower likelihood of sudden departure. The less good news is that children also introduce specific concerns — noise, wear and tear, the logistics of a busy household — that some landlords and buildings are not equipped for.
Not all apartment buildings in Osaka are well-suited to family life regardless of whether they technically permit it. Buildings without soundproofing between floors, thin walls, and neighbors in close proximity create friction for families with young children that accumulates over time and can lead to complaints that complicate the tenancy. The physical quality of the building — not just the apartment — matters significantly for families.
Buildings that have been developed specifically for family households typically have better acoustic separation, communal outdoor space or play areas, and a resident profile that is already accommodating of children. Identifying these buildings requires local knowledge rather than portal filtering.
For families with school-age children, the apartment's location relative to the intended school — local Japanese public school, international school, or a specific program — is typically the most important geographic constraint in the search. This inverts the usual apartment search logic: rather than choosing a neighborhood and then finding a school, families with children often need to identify the school first and then define their search radius around it. This is covered in more detail in the schools section below.
Children are listed on the co-habitant declaration and typically require their own documentation — passport copies, and in some cases resident registration documentation if they are already registered in Japan. For newborns or very young children, some management companies require birth certificate translations. These requirements are not universal but are common enough that having the documentation prepared in advance avoids delays at the application stage.
Osaka's central neighborhoods vary considerably in their suitability for family life. The factors that matter most for families — green space, safety, quiet residential character, proximity to schools, availability of larger apartments — don't always align with the neighborhoods that rank highest for single renters or young couples.
Tennoji Ward, anchored by Tennoji Park and one of Osaka's major transport interchanges, is consistently one of the most popular areas for foreign families. The park provides genuine green space for children, the ward has a range of apartment sizes including 3LDK stock, and the transport connections make central Osaka and Kyoto equally accessible. The ward also has established international community infrastructure — international schools within reasonable distance, foreigner-friendly services, and a resident profile that includes a meaningful proportion of families. Our guide to renting in Tennoji covers the practical rental landscape in detail.
Fukushima Ward's riverside character, newer apartment stock, and proximity to Umeda make it attractive for couples and families who want urban convenience with a quieter residential feel. The Okawa riverside is excellent for children and daily walks. Apartment stock in Fukushima includes a good range of 2LDK and some 3LDK options at more accessible price points than equivalent central wards. Our Fukushima neighborhood guide covers the area in full.
The most central Osaka neighborhoods — Namba, Shinsaibashi, Dotonbori — are vibrant and convenient but not naturally suited to family life with children. Limited green space, predominantly commercial character, high density, and a nightlife culture that doesn't align with early bedtimes are practical constraints. Couples without children often thrive in these areas. Families with young children typically find them exhausting over a two-year tenancy. Our guide to Shinsaibashi gives a realistic picture of what living in that area actually involves.
For families prioritizing space and outdoor access over urban centrality, Osaka's more residential wards — Joto, Higashisumiyoshi, Sumiyoshi — offer larger apartments at significantly lower prices, with quieter streets and more neighborhood-level community infrastructure. The trade-off is commute time and distance from the international community concentration. For families whose children are in local Japanese schools and whose parents have flexible work arrangements, these outer wards are genuinely worth considering. For a broader comparison of Osaka's neighborhoods, our top 10 neighborhoods guide provides the full landscape.
School choice is one of the most significant drivers of neighborhood selection for families with children, and it is worth addressing directly because the options in Osaka are more varied — and the logistics more complex — than families often realize before they arrive.
Osaka has a limited number of international schools offering English-language education, and their locations are not evenly distributed across the city. The Osaka International School in Mino City (north of Osaka), the Canadian Academy and other Kobe-based international schools (accessible via train), and smaller private international programs within the city itself serve the international student community. Families committing to an international school education need to factor commute logistics into their neighborhood decision — a 45-minute school run each morning significantly affects which neighborhoods are practical.
Japan's public school system is organized by residential address — enrollment is at the school whose catchment area (gakku) your address falls within. For families committed to local school integration — a choice that benefits language development and community belonging significantly — the relevant school's quality, distance, and English support provision are geographic constraints on the apartment search.
Osaka's public schools vary in their experience with foreign students. Some wards with established foreign resident communities — parts of Namba, Chuo, and areas around the Korean community in Ikuno — have more infrastructure for non-Japanese-speaking students. Others have less experience. This is local knowledge that doesn't appear on any listing portal.
The sequencing matters: for families with school-age children, the school decision should precede the apartment search, not follow it. Choosing an apartment first and then discovering that the catchment school doesn't have adequate support for a non-Japanese-speaking child, or that the commute to the preferred international school is impractical from that address, is an avoidable problem — but only if the question is asked before the lease is signed.
The financial picture for couples and families renting in Osaka is meaningfully different from that of a single renter, and budgeting needs to reflect the specific cost structure of multi-person households.
The step from a 1LDK to a 2LDK in central Osaka typically adds ¥30,000–¥60,000 per month to the rent. The step from a 2LDK to a 3LDK adds a further ¥40,000–¥80,000 depending on location and building quality. These increments compound significantly over a two-year tenancy and need to be built into household budget planning from the outset.
Upfront costs scale with rent — the deposit, agency fee, and guarantor company fee are all calculated as multiples of the monthly rent. A couple moving into a ¥150,000/month apartment faces upfront costs of ¥600,000–¥750,000, against the ¥450,000–¥500,000 typical of a ¥100,000/month single apartment. Having this capital available and liquid before beginning the search is important — applications can move quickly, and being caught short at the payment stage after an application is accepted is one of the most frustrating outcomes in the rental process.
A larger apartment with more occupants will have higher utility bills — particularly for air conditioning in Osaka's humid summers and heating in winter. A family in a 3LDK should budget ¥30,000–¥40,000 per month for utilities rather than the ¥20,000 figure appropriate for a single-occupant 1LDK. Internet, if not included in the building's management fee, is the same regardless of household size.

Couples and families represent one of the most consistently satisfying client profiles we work with at Maido Estate — the search is more complex, but the outcomes when it goes well are genuinely life-changing. Finding the right apartment for a family moving to Osaka from overseas, with children starting school and both parents managing the transition to a new country, is a materially different exercise from placing a single renter in a 1K near Namba.
We start from your specific situation: the relationship structure, the visa profile of each partner, the income and documentation picture for the primary tenant, the children's ages and school requirements, the timeline, and the neighborhood priorities. From that picture, we approach the market in a way that reflects the full complexity of your household — not a simplified version that fits the standard application template.
For couples where the combined income question matters, we know which management companies will consider it and how to present the case. For unmarried or same-sex couples, we know which buildings and operators have genuinely neutral policies. For families with school-age children, we can provide guidance on school catchment areas and international school commute logistics before the apartment search begins. And for the practical questions — lease structure, co-habitant declaration, children's documentation — we handle the Japanese-language process at full quality, without the translation friction that causes problems at the most critical stages.
We work in English, French, and Japanese across the Kansai region, and the full team is available to the couple or family unit — not just the primary tenant. If you're moving to Osaka as a couple or family and want to understand what's realistically achievable for your specific situation, the most useful first step is a conversation. Use our Room Finder to get started, or contact us directly.
Renting in Osaka as a couple or family is entirely achievable — and in many ways, the stability that a family profile signals to a Japanese landlord is an asset. The complexity lies in the details of how the system processes multi-person households. A few key points:
Osaka is a genuinely excellent city for families — warm, safe, extraordinary for food and culture, with the scale and transport infrastructure to make daily life manageable. Getting the right apartment is the foundation of that experience. It's worth doing carefully.
