A working kitchen and bathroom do not tell the whole story
An akiya may have a kitchen, toilet, bathroom, outlets, and a water heater. That is a useful starting point, but it does not confirm that every system is active, safe, maintained, or ready for the way you plan to use the house.
In rural Japan, water may come from a private well rather than the municipal supply. Gas may be delivered in cylinders instead of through a city pipeline. Wastewater may be handled by a jokaso, an on-site treatment system. Internet service may depend on whether a provider can connect the exact address.
None of these arrangements is automatically a reason to walk away. Many rural homes rely on them without difficulty. What matters is the condition of the system, its maintenance history, and whether it suits your plans for the property.
Before you buy, confirm what serves the house now, whether it is working, and what may need inspection, repair, reconnection, or upgrading after purchase.
Before looking at each system in detail, it helps to see the full picture. A rural property may rely on a mix of public services, private equipment, and local providers.
Before you begin
What to check before you assume a house is ready to use
A rural akiya may have working utilities, but each system still needs to be active, maintained, documented, and suitable for how you plan to use the home.
The five systems to confirm
1Gas: Cooking, hot water, or heating may rely on city gas or LP gas.
2Water: The home may use municipal water, a private well, or another local supply.
3Wastewater: A public sewer, jokaso, or another system may handle household wastewater.
4Electricity: Capacity, wiring, and the electrical panel may need attention.
5Internet and mobile coverage: Service must be confirmed at the exact address.
Why this matters
The issue is rarely that one system is unusual. Rural homes can work well with LP gas, well water, or a jokaso. The risk is buying without knowing whether those systems suit a full-time home, remote work, modern heating, or management from overseas.
Start with gas because it often affects both daily comfort and renovation decisions. The type of supply can shape your choice of cooking, hot water, and heating equipment.
Utility check 01
Gas: City gas and LP gas work differently
Most homes use city gas or LP gas. LP gas is common in rural areas because cylinders can be delivered without a gas pipeline, but the supplier arrangement and equipment still need checking.
First check
Confirm the gas type, the supplier, and whether the existing equipment is usable. City gas arrives through underground pipelines. LP gas is stored in cylinders at the property and delivered by a local supplier.
Questions to ask
□Is the home connected to city gas or LP gas?
□Who is the current LP gas supplier, and is service active, suspended, or disconnected?
□Does the supplier own any existing equipment, and what did the previous owner typically pay?
□Which appliances use gas, and are the water heater, cooker, and other appliances still working?
□Will your renovation keep the gas system, or switch to electric cooking, water heating, or another setup?
Water deserves a closer look because a tap alone tells you very little about the source, condition, or maintenance needs behind it.
Utility check 02
Water: A tap does not always mean public water
Some rural homes use a private well rather than municipal water. The well is only one part of the system, which may also include a pump, pressure equipment, filters, and private plumbing.
First check
Confirm whether the property uses municipal water, well water, or another private supply. If well water is used for drinking, confirm the water-quality history and the maintenance plan for the system.
Questions to ask
□Is the water currently in use, and does the property have municipal water, a well, or both?
□When was the well water last tested, and is it used for drinking?
□How old are the pump and pressure equipment, and when were they last serviced?
□Who maintains the well system, and has the property had water-quality, pressure, or supply problems?
□What is the plan if the pump fails?

Next, confirm what happens after water leaves the house. Wastewater systems are easy to overlook during a viewing, but their condition and maintenance history can matter just as much as the plumbing inside.
Utility check 03
Wastewater: A toilet does not always mean a sewer connection
A property may connect to public sewer or use a jokaso, a decentralized wastewater treatment system on or near the property. A working toilet does not confirm that the system is maintained or in good condition.
First check
Confirm exactly where wastewater goes and what maintenance the system requires. Jokaso systems need ongoing maintenance, cleaning, and inspections. The schedule depends on the system type, size, and local arrangements.
Questions to ask
□Is the home connected to public sewer, a jokaso, or another wastewater system?
□What type of system is installed, how old is it, and is it operating now?
□When was it last inspected and cleaned, and are the records available?
□Which company performs the work, and what does regular servicing cost?
□Is public sewer available, planned, or required under local rules?
Electricity is another system that can look fine at first glance. A few working lights and outlets do not show whether the house can support the way you plan to live in it.
Utility check 04
Electricity: Working lights do not prove the system suits modern use
An older home may have a normal-looking breaker panel while still having limited capacity or aging wiring. Your intended use may place much greater demand on the system than the previous owner's routine.
First check
Confirm the home's current electrical capacity, panel condition, and whether the system can support your plans. Induction cooking, air conditioning, electric water heating, clothes dryers, space heaters, and EV chargers can all change the demand.
Questions to ask
□What is the current electrical capacity, and was service disconnected or reduced while the home was vacant?
□How old are the distribution board and wiring?
□Are there signs of old, damaged, or improvised electrical work?
□Can the system support the appliances you plan to use?
□Will renovation require rewiring, a panel upgrade, or increased capacity?
For many overseas buyers, internet access has become part of basic property suitability. It affects remote work, security monitoring, communication, and how easily you can manage the home from abroad.
Utility check 05
Internet: Check the exact address
Internet availability can matter far more than expected if you plan to work remotely, use security cameras, monitor heating while overseas, stream media, or stay for long periods.
First check
A provider's general coverage map is only a starting point. Even if fiber is available in the town or neighborhood, the exact property may need additional work or may not be serviceable through the existing poles, cable routes, building access, or provider equipment.
Questions to ask
□Is fiber service available at the exact address?
□Which providers can serve the property, and is a fiber line already connected to the house?
□If no line exists, what installation work may be required and how long is it likely to take?
□Is reliable mobile coverage available, and what backup option would you use if fixed internet cannot be installed?
Each of these systems may be manageable on its own. The bigger issue is how several small uncertainties can combine once you begin repairs, reconnection, and regular use.
Budget reality check
The real risk is the combination of small problems
A well, LP gas, a jokaso, or limited internet is not automatically a problem. The risk is discovering several unresolved issues only after you own the property.
Imagine this purchase
A buyer purchases a countryside house for ¥5 million. The price looks manageable. Then they learn that the well pump needs replacement, the electrical system needs work before new heating can be installed, the jokaso has no maintenance records, the gas water heater is near the end of its life, and fiber cannot be connected without further investigation.
What this changes
✓None of these issues necessarily ends the project.
✓Together, they can change the budget, timeline, and intended use of the home.
✓Separate the purchase price from the cost of making the house usable for your actual plans.
Use the questions below as a final pass before making an offer or committing to deeper due diligence. You do not need every answer immediately, but you should know which answers are still missing.
Final pass
A utility checklist before you make an offer
Use this checklist during early due diligence. The aim is to understand what serves the house now, what has been maintained, and what may need work before the home suits your plans.
Water
□What supplies the property with water: municipal water, a well, or another private system?
□If there is a well, when was the water last tested?
□When was the pump last serviced or replaced?
□Is the water suitable for drinking, and are there known supply or quality issues?
Wastewater
□Is the home connected to public sewer or a jokaso?
□If it has a jokaso, what type is it and when was it last inspected and cleaned?
□Are maintenance records available?
□What does ongoing maintenance cost?
Gas
□Does the home use city gas, LP gas, or neither?
□Who is the current supplier, and is service active?
□What did the previous owner typically pay?
□Which appliances use gas, and are they working?
Electricity
□What is the current electrical capacity?
□Are the distribution board and wiring in suitable condition?
□Can the system support your planned heating, cooking, appliances, and charging needs?
□Is an electrical upgrade likely to be part of the renovation?
Internet and communications
□Is fiber available at the exact address?
□Is a line already installed in the home?
□What mobile coverage is available at the property?
□What will you do if fixed internet cannot be installed promptly?
Overall condition
□Which utility services are active and working now?
□Which systems have been unused during the vacancy period?
□What needs repair, replacement, reconnection, inspection, or upgrading before the home is comfortable year-round?
Before you pursue a property
Do not stop at "Does this utility exist?"
Ask what system serves the house, whether it works now, who maintains it, what records are available, and what it may cost to repair, reconnect, or keep working.
Utilities are part of due diligence, not a post-closing surprise. A home can have a working kitchen, bathroom, lights, and water on the day you see it, while still needing repairs or upgrades before it suits your plans.
If you have found an akiya that interests you, start by confirming the systems that affect day-to-day use: water, wastewater, gas, electricity, and internet. This is the kind of practical due diligence AkiyaHub helps buyers complete before they spend serious money on a property.
