​​​​​​​HOW TO EVALUATE A JOB OFFER IN JAPAN: LOOK BEYOND THE SALARY

When considering employment opportunities in Japan, salary is often the first piece of information that attracts a worker’s attention. A position offering a higher salary may immediately appear more attractive, while an opportunity with a lower basic salary can easily be overlooked.

However, based on our experience in recruitment and consultation for Vietnamese workers going to Japan, salary is only one of several factors that should be considered. Two positions with the same basic salary can result in very different levels of actual income and working experience depending on accommodation costs, working hours, overtime, job duties and living conditions.

For this reason, evaluating a job offer in Japan should involve looking at the overall conditions of the position, rather than comparing salary figures alone.

1. Understand the actual job duties first

The occupation stated in a recruitment announcement does not always provide a complete picture of what workers will do on a daily basis.

For example, within food processing, the actual duties may involve preparing ingredients, processing food, packaging products, checking products or cleaning production lines.

Similarly, construction positions can differ considerably depending on the specific type of work and the skills required.

Before focusing on salary, workers should find out:

• What will the daily duties actually involve?

• Will the work take place indoors, outdoors or on a construction site?

• Does the job require prolonged standing, frequent movement or lifting?

• Are there particular working conditions such as heat, cold or noise?

• Will workers receive training before starting the job?

Understanding the actual nature of the work allows workers to assess whether they are suited to the position and reduces the risk of choosing a job based only on a short recruitment description.

2. Basic salary is not the same as actual income

This is an important point when comparing job offers in Japan.

The salary shown in a recruitment announcement is usually the basic salary or hourly wage, while the amount a worker actually receives depends on various other factors.

A monthly income can be considered broadly as:

Salary and allowances + overtime pay – taxes – social insurance – accommodation costs – living expenses = remaining income

Overtime income also depends on production conditions, seasonal demand and the employer’s actual work schedule. Therefore, workers should not automatically assume that an overtime level mentioned during recruitment will remain unchanged throughout the contract.

When comparing positions, it is more useful to consider both income and expenses rather than focusing solely on basic salary.

3. Overtime should be clarified

Overtime can have a significant effect on monthly income, but it is also one of the factors that can be difficult to predict based only on a figure provided during recruitment.

Workers should ask:

• Is overtime regularly available?

• Is the stated overtime based on actual working conditions or an average figure?

• Is work performed on days off?

• Does the job have seasonal fluctuations?

A position with a moderate basic salary but relatively stable working hours and regular overtime may produce a different level of actual income from a position with a higher basic salary but limited overtime.

Therefore, “overtime is available” and “how much overtime is actually available” should be treated as two separate pieces of information.

4. Living costs in the area should be included in the calculation

The location of a job directly affects living expenses.

Rent, electricity, water, transportation and other daily expenses can vary depending on the region.

Workers should therefore check:

• Monthly accommodation costs;

• Any deductions related to company housing or dormitories;

• Distance between accommodation and workplace;

• Transportation arrangements;

• General living costs in the area.

Two positions offering similar salaries may result in different amounts of savings if accommodation and transportation costs differ.

5. The location is about more than the cost of living

The prefecture or city where a worker will live and work also affects their overall experience in Japan.

It is worth considering whether the workplace is located in an urban area, suburban area or regional community, as well as access to public transport, shopping facilities, hospitals and other essential services.

For people travelling abroad for the first time, the living environment is another factor that should be considered.

Living in an area with a relatively small Vietnamese community can provide a different experience from living in a location where many Vietnamese workers are already based.

There is no single location that suits everyone. The important point is for workers to understand the living and working environment before making a decision.

6. Working conditions should be considered together with the job itself

In addition to the job description, workers should understand the actual working conditions.

Some useful questions include:

• What are the daily working hours?

• Is shift work required?

• How are days off arranged?

• Does the job require significant physical effort?

• Is the working environment hot, cold or noisy?

• What occupational safety equipment is provided?

These factors are particularly relevant to manufacturing, food processing, construction and agriculture, where working conditions can differ considerably between employers.

7. Recruitment requirements need to match the individual worker

A job should not be evaluated simply by looking at its salary.

The position needs to be compatible with the applicant’s ability to meet the recruitment requirements.

Age, gender where specified by the employer, Japanese-language ability, previous experience, physical condition and any other job-specific requirements should all be considered.

Workers should also assess honestly whether they can adapt to the nature of the job.

A position with an attractive income may still be difficult if its physical requirements or working environment do not suit the worker.

8. The receiving company and working environment also matter

For workers, the receiving company will become their workplace for a significant period of time. Information about the employer therefore has a place in the decision-making process.

Workers can research:

• The company’s size and business sector;

• Actual job duties;

• Working environment;

• Workforce structure;

• Accommodation arrangements;

• Living conditions;

• The company’s experience in employing foreign workers.

For positions where the company has previously employed Vietnamese workers, information from people who have actually worked there can also help applicants develop a clearer understanding of the job and daily life.

9. Consider career development after the internship period

This is becoming an increasingly relevant consideration for workers.

The way a person chooses a job may differ depending on whether they intend to return to Vietnam after completing the programme or hope to continue working in Japan.

Those considering a longer-term career may wish to examine:

• Whether the job provides useful professional experience;

• Whether it offers opportunities to improve Japanese-language skills;

• Whether the occupation is relevant to the Specified Skilled Worker pathway;

• What options may be available after completing the programme.

From this perspective, a job should not be evaluated only by monthly income. The skills, experience and professional knowledge that workers can accumulate during their time in Japan can also have value for their future career.

10. Make a comparison table before making a decision

When several positions are available, workers can create a simple comparison table:

This approach can help workers avoid making a decision based on one prominent piece of information in a recruitment advertisement.

11. Questions to ask before applying for a position

Before making a decision, workers can ask the recruitment organisation to clarify the following:

Job duties: What exactly will I do during a typical working day?

Income: What is the basic salary, what allowances are available and how is overtime calculated?

Costs: Which costs need to be paid before departure and which expenses may arise after arriving in Japan?

Living arrangements: How are accommodation, electricity, water and transportation costs calculated?

Working hours: What are the working hours, shift arrangements and days off?

Career pathway: What options may be available after completing the programme?

Asking specific questions helps workers understand the position more clearly and prepare more realistically for working and living in Japan.

12. A job offer should be evaluated from several perspectives

As Vietnamese workers have more overseas employment options and Japan’s foreign worker system continues to evolve, evaluating a Japanese job offer requires a broader perspective.

Salary indicates the contractual level of income.

Overtime can affect actual earnings but depends on the real working situation.

Living expenses influence how much income can potentially be saved.

Job duties and working conditions affect the worker’s ability to adapt.

Location influences daily life.

The occupation and skills gained may be relevant to future career development.

For this reason, when receiving a job offer, workers should take time to understand the full set of conditions rather than focusing only on the advertised salary.

For those preparing to work in Japan during 2026–2027, job selection can also be considered as part of a longer career plan: what skills do I want to gain while working in Japan, do I intend to return to Vietnam and develop my career there, or do I plan to continue working in Japan through a programme that matches my circumstances and eligibility?

A decision based on sufficiently detailed information can help workers prepare more proactively and adapt more effectively to their work and daily life in Japan.
