A property can look right on paper and still be wrong for what you want to do with it. Before comparing individual listings, decide how you intend to use the property. That decision affects which homes are suitable, which restrictions matter, and—if you need a loan—which properties you can realistically buy.
Start with the intended use and financing
Are you buying a home to live in, a second home to use when you visit Japan, or a property to rent out? These purposes can overlap. A second home, for example, may also earn income while you are away. The question is what you want to prioritize: shorter stays generally offer higher rental income, but more guest turnovers increase the chance of damage. Longer stays mean fewer turnovers, but gaps between contracts can be harder to fill because each renter needs a longer block of time.
If you need financing, establish your options before narrowing the search. Lenders have different requirements concerning the borrower and the property, including its location, age, structure, and intended use. A property that suits your plans may still fall outside a lender’s criteria. Knowing what you can finance helps you avoid spending time on homes you cannot buy on the terms you need.
Which property type fits your purpose?
For your own home, both condominiums and houses offer a broad range of choices. Specific requirements can narrow that range. If you have pets, play an instrument, or need a particular type of parking, check each condominium’s rules rather than assuming the unit can be used as you wish. A house may offer more freedom, although it comes with direct responsibility for its maintenance.
For a second home, decide what matters more while you are away. If you want fewer turnovers, more predictable ownership, and the home treated with more care, a condominium with a building manager may be a better choice if rented out as a furnished rental for 30 nights or longer. If you want to maximize rental income, look for a house that can qualify for nightly accommodation under Minpaku or a Hotel/Ryokan license. Shorter stays can offer higher income potential, but bring more frequent guest turnovers.
Neither option is automatic. Condominium rules must be checked if you intend to offer shorter stays, while a house’s location, building specifications, fire safety requirements, and local rules affect whether accommodation use is possible. Even wording that appears to rule out monthly rentals may need clarification, as we found in one condominium we investigated.
For a rental investment, decide what kind of income you are seeking. Condominiums with a building manager, rented on longer leases, generally provide steadier but lower profits. Houses eligible for short-stay accommodation are generally more profitable, but their income is more volatile.
These distinctions help you choose where and what to search. They do not tell you whether a particular condominium or house is a good purchase. That takes a second round of checks.
Check the individual property
If it is a condominium
Confirm whether the ownership includes the land or is subject to a land lease. Review the management rules for any restrictions that affect your plans, and find out whether building management is outsourced or handled by the owners themselves. Self-management may require more direct involvement than an owner expects.
Then look beyond the unit’s condition. Management fees and repair reserve contributions are recurring ownership costs. Request the condominium’s management condition report (重要事項調査報告書) and review arrears, the association’s reserves and borrowings, planned fee increases, past repairs, and the long-term repair plan. Recent meeting agendas and minutes, if available, can help you understand whether owners are willing and able to make decisions about the building.
The question is not simply whether the building is old or whether a repair plan exists. It is whether necessary work is likely to be funded and carried out. A low monthly reserve contribution may look attractive today but become a problem when major repairs are needed in the future.
If it is a house
Confirm the land ownership, boundaries, and any structures crossing a boundary. If there is an encroachment, ask whether the neighbours have a written agreement about it. Check how water, drainage, gas, and electricity reach the property, particularly if any pipes or connections cross another person’s land.
Road access deserves particular attention because it can affect rebuilding and some changes of use. Ask for the building approval and any available inspection records to confirm whether the building was legally constructed. For an older house, review known defects and repair history. Neighbourhood arrangements, including any local association obligations, are also worth asking about.
These checks are especially important if your plans involve renovation or accommodation use. A house that works as a residence will not necessarily qualify for the business you intend to run. We have written separately about checking licensing suitability before buying.
What if information is missing or a problem turns up?
Ask for the missing document or a clear answer first. If the seller needs to resolve something—such as providing records, clarifying a boundary, or completing an agreed repair—find out whether they are willing and able to do so, and when.
If they cannot, establish whether you can resolve the issue yourself and what it would cost. Then decide whether the price and terms still make sense. Some problems can be addressed through work, time, or negotiation. Others prevent the property from serving the purpose for which you wanted to buy it.
Before making an offer, make sure the property suits your intended use—and that you understand the costs and issues you would be taking on. Browse our properties to start your search. If you are unsure which type of property fits your plans, tell us what you want to do with it.
