Common problems related to keys and security
Problems with keys and security are particularly common in weekly apartments. These issues can be prevented by confirming key handling rules and emergency contact information upon check-in. This is especially important for first-time weekly apartment users. Here, we'll explain some examples.
I forgot to take my keys! I can't get back to my room from where I am...
A common problem with weekly apartments is forgetting to take your keys with you.
It's not uncommon for people to leave their apartments to take out the trash or do a quick errand, only to find themselves trapped inside when the automatic lock activates. This is especially true for short-term stays when living alone, as people may leave their smartphones and wallets inside, making it impossible to contact the management company.
To avoid problems, it's important to always keep your keys with you and to note down emergency contact information when you check in.
Lost your keys? Reissuing them can be expensive!
Losing your keys to a weekly apartment can cost anywhere from several thousand yen to over ten thousand yen for replacement. Furthermore, depending on the type of lock, cylinder replacement may be necessary, potentially resulting in a bill of tens of thousands of yen.
Even for short stays, managing your keys is your own responsibility. It's crucial to confirm the details of what happens if you lose your keys and who will be responsible for any costs involved when you sign the contract. Using a keychain or neck strap when going out is also an effective way to prevent losing them.
Be careful of being locked out by automatic locks.
While weekly apartments with automatic locks offer high security, lockouts are also a frequent problem. It's important to be careful, as leaving the key inside the apartment will automatically lock the door when you go outside.
Particular caution is needed immediately after check-in and during the initial period of your stay when you're still getting used to things. Some buildings offer spare keys or emergency response services, but these may have time limits and incur fees. It's best to check in advance for peace of mind.
Common problems with equipment and fixtures
While weekly apartments offer the convenience of furnished accommodations, problems with equipment and fixtures are also common. It's important to check that all equipment is working correctly upon moving in and to contact the management company immediately if any problems occur. Checking reviews beforehand is also a good way to avoid equipment issues.
The air conditioner isn't working and it's making a lot of noise.
A common problem with weekly apartments is that the air conditioner doesn't work well or makes strange noises. This can be particularly stressful during summer and winter stays. The cause is often a dirty or worn filter, so checking it before use is key.
If you hear popping or rattling noises while using the appliance, contact the management company as soon as possible. Testing the appliance immediately after check-in will help ensure a smooth initial response.
My induction cooktop isn't working / I don't know how to use it.
Struggling with the operation of an induction cooktop is a common experience when staying in a weekly apartment. If it's not responding, possible reasons include not using an induction-compatible pot, the power being off, or the setting being locked. Since the operation method varies depending on the model, be sure to carefully check the included instruction manual.
Before using unfamiliar equipment, it's a good idea to perform a simple operational check to ensure peace of mind.
The shower has weak water pressure or leaks.
Weak water pressure in the shower or leaks from the showerhead can significantly reduce your comfort during your stay. Plumbing problems are especially common in older properties, so checking beforehand is crucial. If you notice any issues, contact the real estate company immediately and request repairs. Checking reviews about the "plumbing" before your stay is also a good strategy.
Toilet or toilet seat malfunctions (e.g., not heating up)
Regarding toilets in weekly apartments, common problems include issues such as "the toilet seat doesn't heat up" or "the bidet doesn't work."
Especially in winter, since comfort is directly related, it's reassuring to check that everything is working on the first day. Sometimes the cause is something simple like the power cord being unplugged or the remote control batteries being dead, so it's a good idea to actually try checking it yourself if it's within your capabilities.

Common troubles with noise and neighbors
One surprisingly common issue with weekly apartments is neighborly disputes, such as noise. Because many residents are short-term tenants, their lifestyles and manners can differ, and complaints about noises like talking, television, and footsteps at night are frequent occurrences.
This chapter will discuss potential problems.

Daily noise troubles
Common everyday noise problems include the sound of televisions, music, phone calls, footsteps, and showers from the next room. Weekly apartments have a much higher turnover of tenants compared to regular rentals, and conflicts often arise due to differing lifestyles and noise levels.
Noise, especially at night, can be a major source of stress. If it bothers you, you can first consult with the management company, as they may be able to intervene and bring the noise to the attention of the neighbors. It is preferable to have a third party handle the situation rather than confronting the neighbors directly.
In some cases, the building structure can make it easier for sound to resonate.
The building structure of weekly apartments varies from property to property, including steel frame (S-structure) and wood frame (W-structure). This results in significant differences in how easily sound travels. Wooden buildings and older properties, in particular, have poor soundproofing, and everyday noises from neighboring rooms and the floors above and below can easily be heard.
It's a good idea to check the structure beforehand and look for reviews that mention noise issues. If you are sensitive to noise, choosing a reinforced concrete (RC) building will reduce the chances of disappointment.
"It's not what I expected!" Real-life stories of discrepancies between expectations and reality.
A common complaint about using weekly apartments is that they "weren't what they expected." This is especially true when booking based solely on photos and descriptions without a prior viewing; many people are surprised by the small size of the room or the quality of the facilities after moving in. Checking reviews and testimonials is crucial to avoid this disappointment.
Signed a contract without viewing the property → The room was smaller and darker than expected.
With weekly apartments, due to their short-term nature, it's not uncommon to sign a contract without viewing the property beforehand.
However, upon actually moving in, many people express disappointment, saying things like, "It's smaller than it looks in the photos," or "It's dimly lit even during the day because it doesn't get much sunlight." This tendency is particularly pronounced in older properties and rooms on lower floors. If you can't view the property in person, be sure to check the actual size (in tatami mats), orientation, and reviews to get a realistic idea of what it will be like, which will help prevent disappointment.
The bedding and kitchen equipment were simpler than I expected.
Even though properties are advertised as "furnished with appliances," in reality, they often only have the bare minimum, and many people are disappointed with the quality of the bedding and cooking utensils in particular. The bedding can be thin and uncomfortable, and the kitchen may have pots and pans that are too small, making it unsatisfactory for those who like to cook for themselves.
Checking the equipment list in advance and preparing to bring or purchase additional items if necessary will help ensure a more comfortable stay.
The photos and reality are so different... it's a classic case of fraud.
It's common for photos to appear more beautiful and wider than they actually are due to professional wide-angle lenses and editing.
Weekly apartments also frequently fall victim to this "photo scam," with complaints such as "It looked clean, but it smelled musty" or "It looked new, but it was actually in terrible condition."
Choosing a reliable operating company and referring to Google Maps Street View and reviews with photos from actual users are key to minimizing discrepancies.

Pitfalls related to contracts and usage rules
Using a weekly apartment comes with its own unique rules that differ from those of a typical rental. There are many points to be aware of, especially because of the short-term nature of the contract. Many users are surprised by unexpected restrictions, such as the inability to register residency, refund issues upon early termination, and restrictions on guests staying over.
Even if these details are included in the pre-contract explanation, they are often overlooked due to small print, so prior confirmation is essential. To avoid regrets, be sure to carefully check the contract and terms of service.
There are cases where resident registration is not possible.
Because weekly apartments are for short-term stays, many properties do not allow you to change your registered address. Even if you need to change your address due to employment, relocation, or moving to a new city, you may not be able to register your address depending on the contract type and the management company's policies.
Since this could affect various procedures requiring proof of residence (such as driver's license renewal and insurance enrollment), it is essential to confirm whether or not you can register your residence before signing a contract. This is especially important for those considering long-term use.
Problems with not being able to cancel the contract midway and not receiving a refund.
Weekly apartments are generally paid for in full upfront, and refunds may not be given even if the contract is terminated early. Even in unavoidable circumstances such as a sudden job transfer or illness, there are cases where refunds are not provided according to the terms and conditions, so caution is advised.
If the rental period is uncertain, the key to avoiding problems is to check the cancellation policy and whether pro-rata payment is possible in advance and choose a property that offers flexible options.
Arguments can arise over rules prohibiting friends from staying over.
While it's easy to think "it's okay to have a friend stay over for just one night," some weekly apartments prohibit guests other than the contract holder from staying overnight. In many cases, prior application is required, and unauthorized stays can lead to trouble and additional charges.
If you are deemed to have violated the rules, you risk eviction or penalties, so be careful. If you are planning to have friends or your partner visit, be sure to check with the management company in advance.
What to do if a problem occurs? Appropriate solutions.
When problems such as equipment malfunctions or noise disturbances occur in a weekly apartment, calm and appropriate responses are crucial. Especially with short-term contracts, the speed of problem resolution can greatly affect the comfort level of your stay.
Here are some ways to deal with problems that may arise.
First, contact the management company immediately! Keeping their contact information is essential.
When a problem occurs, it's essential to contact the management company immediately. Especially for issues like equipment malfunctions, lost keys, or neighbor disputes, don't try to handle it yourself; consult them promptly.
The information sheets and contracts you receive at check-in often contain emergency contact information, so it's helpful to take a picture of them with your smartphone. It's also a good idea to check in advance whether they provide support during nighttime hours and on holidays.
Taking photos and videos as evidence will make subsequent negotiations smoother.
If you experience any damage to equipment or problems with your room, take photos or videos with your smartphone to keep as evidence. Keeping records is very effective in avoiding disputes regarding the cost of restoring the property to its original condition or whether any damage occurred when you move out.
Furthermore, sending images along with your report to the management company can lead to a quicker and more accurate response, and prevent unnecessary misunderstandings. Prompt action is especially crucial for issues that occur immediately after check-in.
Make sure to check the "inquiry system" when you first sign the contract.
The ability to handle problems is a major factor in determining the comfort level of a property. Before signing a contract, be sure to check whether there is a contact point, how to contact them (phone, email, LINE, etc.), and their operating hours.
Whether or not they offer 24-hour service, or if they're closed on weekends and holidays, greatly affects your sense of security. Especially for first-time weekly apartment users, checking the inquiry system in case of an emergency is the first step to avoiding problems.
