Updated: July 2025, 12
The Warehouse Manager is a newly established qualification following the "Warehouse Business Law Amendment" that came into effect on April 1, 2002.
This qualification certifies individuals with the specialized knowledge and ability to properly manage warehouses, and covers a wide range of tasks including disaster prevention, maintenance, and management of warehouses.
Specifically, the job duties include preventing fires in warehouses and other facility management, ensuring the proper operation of warehouse management operations, preventing work-related accidents, and training on-site employees.
Under the Warehousing Business Act, companies operating in the warehousing business are required to appoint one warehouse manager for each registered warehouse.

Warehouse operators must meet the requirements stipulated by the Ordinance of the Ministry of Land, Infrastructure, Transport and Tourism as having the necessary knowledge and ability to properly manage warehouses, in accordance with the scale of the warehouse to be managed and other standards specified by the Ordinance of the Ministry of Land, Infrastructure, Transport and Tourism. A chief administrator must be appointed to perform the prevention of fires in the warehouse and other tasks related to warehouse management as specified by Ordinance of the Ministry of Land, Infrastructure, Transport and Tourism.

Warehouse Manager Job Description
Warehouse managers are responsible for the important work of ensuring the safe and efficient operation of registered warehouses.
Specifically, they have four main roles: preventing fires in warehouses and managing other facilities, ensuring the proper operation of warehouse management operations, preventing industrial accidents, and training on-site employees.
These operations are essential for maintaining the public nature of the warehousing industry and contributing to the smooth flow of logistics.
The role of a warehouse manager is to properly manage both the hard and soft aspects of the warehouse and provide a safe working environment.
For example, facility maintenance and disaster prevention measures are considered hard management, while storage and loading management and employee training are considered soft management.
Warehouse management supervisors perform the following duties at registered warehouses.
1. Prevention of fires in warehouses and other matters related to the management of warehouse facilities
“Management of warehouse facilities” refers to general management work performed from the hardware side of warehouses, such as daily maintenance work related to warehouse buildings and work to prevent accidents such as fires.
Although warehouses are capable of storing large amounts of flammable materials, they have few openings such as entrances and windows, making it difficult to exhaust smoke in the event of a fire, and the interior of the warehouse can easily become filled with smoke and heat.
This situation significantly complicates firefighting efforts, increases the risk of damage to stored items, and potentially threatens the safety of employees.
Therefore, warehouse managers have an important responsibility to take thorough preventive measures to prevent fires from occurring and to minimize damage in the event of a fire.
Specific fire prevention measures, as outlined in the Ministry of Land, Infrastructure, Transport and Tourism's "Warehouse Management Supervisor Manual," include preventing fires during construction, preventing fires caused by cigarettes, preventing explosions caused by spontaneous combustion or dust, preventing fires caused by electrical leakage or explosions of designated flammable materials, preventing fires in automated warehouses, and even preventing fires caused by arson and large-scale fires.
In addition to these measures, other important duties include regular inspections of fire prevention equipment such as fire hydrants and sprinklers, educating on-site employees on fire prevention measures, and conducting evacuation and initial firefighting drills.
In addition, proper management of electrical equipment that may lead to electrical leakage is also an essential element in preventing fire accidents.
Through these wide-ranging management tasks, warehouse managers are responsible for ensuring the safety of the warehouse and supporting smooth logistics.
2. Matters related to ensuring proper operation of warehouse management operations
To ensure proper operation of warehouse management operations, it is essential to properly manage the cargo stored in the warehouse and ensure smooth inbound and outbound operations.
It is not enough to simply store items; we are also required to store and manage them in the correct way according to their quality and purpose.
For example, careful attention must be paid to temperature, humidity, ventilation, and how items are stacked, in order to prevent deterioration and damage.
These specific tasks form the core of a warehouse manager's job description.
Furthermore, warehouse operators are required to maintain confidentiality of cargo and must never disclose to outsiders any information they learn in the course of their work, such as the type, quantity, value, or business partners of stored items.
Ensuring this confidentiality obligation and establishing an information management system are also important roles of the warehouse manager.
The Ministry of Land, Infrastructure, Transport and Tourism's "Warehouse Management Supervisor Manual" provides detailed guidelines for carrying out such appropriate warehouse management tasks, listing specific tasks such as patrolling inside and outside the warehouse, inventory quantity management, storage management in trunk rooms, constant temperature and humidity warehouse storage management, and issuing inventory certificates.
It is also important to ensure that the warehouse terms and conditions and fee schedules are always up to date and posted in an easily visible manner.
This is a necessary measure to provide a highly transparent service and prevent any problems with customers, and falls within the scope of responsibility of the warehouse manager.
Through these operations, proper management of the software aspects of the warehouse will ensure proper operation of warehouse management operations and improve the reliability of the entire logistics system.
In addition, this refers to the general management work carried out from the soft side of the warehouse, such as storage in the warehouse and management of loading and unloading operations, but does not include tasks such as setting fees and management.
3. Matters related to the prevention of industrial accidents
Refers to general work performed to prevent industrial accidents for workers engaged in cargo handling work in warehouses.
In warehouses, dangerous work is constantly being carried out, such as using heavy machinery such as forklifts, working at heights, and moving cargo.
Therefore, warehouse managers must prevent work-related accidents caused by the above and ensure the safety of employees.
Specifically, as stated in the Ministry of Land, Infrastructure, Transport and Tourism's "Warehouse Management Supervisor Manual," it is necessary to thoroughly check the health status of workers, inspect their clothing, and implement safety management appropriate for each individual task, such as loading and unloading, forklift work, conveyor work, and crane work.
Taking measures to prevent accidents such as falling, tripping, flying objects, and tipping over is also an important part of the warehouse manager's job.
By implementing these measures thoroughly, employees will be able to work with peace of mind, which will ultimately lead to improved productivity throughout the warehouse.
Preventing industrial accidents is not just about ensuring the safety of employees; it is also an essential role for maintaining proper warehouse operations, and the warehouse manager has a very large responsibility.
4. Regarding training for on-site employees
This refers to the work of planning and implementing training for on-site employees in order to contribute to the smooth implementation of warehouse operations.
According to the Ministry of Land, Infrastructure, Transport and Tourism's "Warehouse Manager Manual," warehouse managers must thoroughly educate and train all employees, both full-time and temporary, to ensure safe and efficient warehouse operations.
This training will raise safety awareness among all employees and help them develop the ability to avoid danger.
For example, the instructions cover a wide range of topics, such as following the shipping and receiving slips when performing shipping and receiving work, keeping the warehouse tidy and clean inside and outside the warehouse, patrolling the inside and outside of the warehouse, and paying close attention to fire prevention.
Other important instruction items include thorough initial inspections, creating and storing work logs upon completion of work, and making sure to report to the person in charge.
Specific guidance is required according to the type and purpose of the warehouse, such as thorough handover of information regarding cargo maintenance management and prompt reporting to on-site personnel in the event of theft, fire, or equipment damage.
This training is fundamental to the role of a warehouse manager and is essential for ensuring smooth warehouse operations in all areas.
Reasons for appointing warehouse managers
The appointment of a warehouse manager is an important system that is mandatory for registered warehouses under the Warehousing Business Act.
The purpose of this system is to ensure the safe and proper operation of warehouses, and given the important role that the warehousing industry plays as part of social infrastructure, it is extremely necessary.
Warehouse managers are responsible for a wide range of tasks, including safety management to prevent fires and industrial accidents, ensuring the proper operation of warehouse management operations, and training on-site employees, and they serve as the person in charge of the warehouse site.
As a general rule, the standard for assigning warehouse managers is one per warehouse.
However, under certain conditions, one warehouse manager may be sufficient for multiple warehouses.
For example, in the case of warehouses located on the same premises or multiple warehouses whose functions are considered to be one, or multiple warehouses directly managed and supervised by the same office and located in the same prefecture, if the total effective area of those warehouses is less than 10,000 square meters, the figure set by the Minister of Land, Infrastructure, Transport and Tourism, one person can handle the work.
However, if a certified storage room is located in multiple warehouses, the area of the certified storage room will not be included in the total.
The method for calculating the effective area varies depending on the type of warehouse, and is specified in detail, such as multiplying the effective area by 0.5 for open-air warehouses and water-surface warehouses, and multiplying the effective volume by 0.2 for storage tank warehouses and refrigerated warehouses.
For hazardous materials warehouses, the calculation is made by multiplying the effective area by 2.0 for buildings and the effective volume by 0.4 for tanks.
The total value of the effective area is the sum of the figures calculated using these methods, and if this total value is 1 square meters or less, one warehouse manager is required. However, please note that this standard does not apply if the warehouses are not in the same prefecture.
These placement standards are detailed in Article 8 of the Enforcement Regulations of the Warehousing Business Act and the Ministry of Land, Infrastructure, Transport and Tourism's "Notice Concerning Standards for Registration under Article 3 of the Warehousing Business Act," and serve as important guidelines for establishing an appropriate management system according to the size and type of warehouse.
