In many countries, homes have better soundproofing than in Japan, so people's perceptions of noise vary. Furthermore, some countries have a culture of socializing late into the night, which can clash with Japanese lifestyles.

For example, there have been reported cases of people playing loud music late at night, inviting friends over for large parties, and talking or watching TV at high volumes. According to a "Survey on Foreign Tenants" (2022) conducted by the Japan Rental Housing Management Association, 54.2% of foreigners who had been warned about noise pollution during their tenancy said they were "warned about making too much noise."

To prevent such issues from occurring, our company explains Japanese lifestyles (especially regarding quiet hours at night) at the time of signing a lease. Furthermore, if a report is made, we immediately contact and warn tenants.

Many countries do not have garbage sorting systems, or they are not as strict as Japan's. Furthermore, there may be no concept of designated days or designated bags in their home country, leading to problems such as unsorted garbage, garbage disposal on days other than the designated days, or garbage disposal without the designated bags. According to a survey, 52.1% of foreign residents who had received a warning during their tenancy responded that they were "warned about garbage disposal procedures."

This shows that garbage disposal-related problems are quite common.

To prevent such problems, our company utilizes multilingual garbage sorting guides provided by local governments and provides illustrated calendars to clearly communicate designated days. If the problem persists, we will provide individual warnings. In Sendai City, the types of garbage that can be disposed of on different days of the week vary depending on the area, so residents will need to get used to it.

Odor problems are often caused by differences in culture and dietary habits. While commonplace in your home country, strong-smelling dishes that use a lot of spices and oil, or the use of incense for religious reasons, are unfamiliar to Japanese people. Some people are sensitive to odors, which can be stressful.

Other issues include inappropriate use of common areas and poor etiquette. In many countries, rules regarding the use of common areas are not as strict as in Japan, and it is common to leave personal belongings there. Some residents also bring their home apartment habits with them and fail to adapt to the rules of Japanese apartment living.

Behaviors such as leaving personal belongings in hallways or balconies, monopolizing common spaces, monopolizing shared facilities, and ignoring rules regarding bicycle parking and how to park are common causes of odors.

To prevent such problems, our company provides daily ventilation and deodorization measures, as well as detailed explanations of the rules for using common areas. We highlight prohibited activities and regularly check common areas, and if there are any issues or reports, we take prompt action to address them. However, providing clear explanations in advance can help residents avoid these issues.

Many countries have a culture that is tolerant of temporary residents and visitors, and attitudes toward cohabitation can differ from those in Japan. There are also cases where people choose to live together with multiple people for economic reasons.

Specific examples of problems have been reported, such as people letting friends or family members who are not the contract holder live with them without permission, or subletting rooms to third parties.

According to the aforementioned survey, of foreigners who had been reprimanded while renting, 29.2% answered that they were reprimanded for "living together without permission."

To prevent such problems, our company clearly explains the restrictions on the number of people living together at the time of signing the contract, and we also clearly explain and understand the penalties that will be imposed in the event of a breach of contract.
