When living in a rental apartment, you may encounter the terms "management association" and "management company." These are two separate organizations with different relationships to tenants. This guide explains the differences and roles of each so you can contact the right organization if a problem arises.

This guide explains how to effectively request repairs from your management company when water leaks, equipment failures, or roof leaks occur in your rental home. Learn what to communicate and how to communicate it, how to keep records, how to think about cost responsibility, and what to do if your management company is slow to respond—all explained in detail by rental property professionals.
Many areas in apartment buildings leave residents wondering: "Is this my responsibility or the landlord's?" This guide explains the practical rules for management responsibility and repair cost allocation for ambiguous areas like entry doors, windows, balconies, and pipes.
Rental properties are managed either by "property management companies" or through "self-management (owner management)." Since trouble response, repair speed, and contact procedures differ significantly, it's important to verify the management type before moving in.
When living in a rental apartment, you may hear the terms "management association" and "management company." Though these are completely different organizations, they are often confused, leading to uncertainty about which one to contact when a problem arises.
Let's start with the basics.
| Management Association | Management Company | |
|---|---|---|
| Members | Unit Owners | Real Estate Management Professionals |
| Role | Self-governance and decision-making for the building and common areas | Implementation and execution of management operations |
| Legal Basis | Building Owners' Association Act | Management Service Contract |
| Costs | Unit owners bear maintenance fees and repair reserves | Management Association pays management service fees |
In short, a management association is a self-governing organization of apartment owners, while a management company is a professional firm hired by the management association.
In an apartment building (divided ownership building), each unit owner automatically becomes a member of the management association under the law (Building Owners' Association Act). The moment an owner purchases a unit, they become an association member.
In the case of rental properties, residents (tenants) are not unit owners, so they are generally not members of the management association. However, when an owner of an investment apartment rents out their unit, that owner is a management association member.
Rental residents generally have no direct contact with the management association. Maintenance fees and repair reserves are paid by owners to the management association, not by tenants (though tenants may indirectly bear this cost as part of their rent).
However, building bylaws established by the management association do apply to tenants. Rules such as "no pets," "no musical instruments," and "garbage disposal guidelines" are often based on these bylaws, so it is important to review them in your rental agreement.
A management company (apartment management company) carries out building operations on behalf of the management association under a management service contract. There are numerous management companies throughout Japan, and major ones include Daikyo Astage, Hasekō Community, and Sumitomo Realty & Development Building Services.

The most common situations in which rental residents contact the "management company" include:
However, in rental properties, residents' initial point of contact is usually the "rental management company (or landlord)," not the "apartment management company." Issues are typically handled through the management company or landlord associated with your rental agreement.
When the term "management company" is used in the context of rental housing, it is important to distinguish between the following two:
A company that handles rental agreements with tenants, responds to day-to-day complaints, and collects rent on behalf of the landlord (owner).
A company contracted by the management association to maintain common areas. It generally has no direct contractual relationship with rental tenants.
Generally, rental tenants should contact ① the rental management company (or landlord).
For problems such as a broken faucet, a non-functioning air conditioner, or a broken lock, contact the rental management company or landlord. Repairs to private units are the landlord's responsibility (under Civil Code Article 606), so you should first notify the landlord.
For problems such as a non-functioning elevator, a burned-out corridor light, or a crack in the building exterior, contact the rental management company, which will then contact the apartment management company. In emergencies, you can contact the apartment management company's emergency hotline directly. The management company's contact information is usually posted at the entrance or on the building notice board.
Contact the rental management company or landlord first. The management company will then contact the neighboring unit's owner or resident.
Building bylaws apply not only to unit owners but also to occupants (including rental tenants) (Building Owners' Association Act Article 6).
In other words, rules stipulated in building bylaws (pet prohibition, restrictions on musical instrument playing times, garbage disposal methods, etc.) must be followed by tenants.
When moving in, confirm whether you "received a copy of the building bylaws (or house rules)." If you did not receive one, request it from the real estate company or landlord.
When a problem arises in a rental apartment, contacting the wrong party can delay resolution. It's helpful to note down the contact information for both the "rental management company" and the "apartment management company" at the time you move in.
