The real cost of working in Japan: what to budget before you go

Before you arrive in Japan, there are real preparation costs that vary by your starting point. Language study materials and test registration (JLPT or SSW language test) typically cost between 3,000 and 15,000 Vietnamese dong equivalent depending on format. Skills assessment tests for SSW typically charge a registration fee — usually under 5,000 JPY per test attempt.

Document preparation costs include translation fees for certificates and identity documents, medical examination fees (required for most visa applications), and passport renewal if needed. Across these items, a realistic pre-departure cost estimate for a prepared applicant is 5 to 15 million VND total, not counting airfare.

Airfare is often covered by the employer or the sending organization in legitimate placements — but always confirm this in writing before you pay for it yourself.

Japanese salaries are quoted before deductions. The gap between gross pay and take-home pay surprises many first-time workers. Standard deductions include: health insurance (approximately 5% of gross), pension contributions (approximately 9% of gross), and income tax (variable, but often 5% to 10% at SSW wage levels).

From your second year in Japan, you will also pay residence tax (住民税, juuminzei) — a municipal tax based on the previous year's income. This is often not mentioned before arrival but typically adds 5 to 7 percent of gross income annually. It is paid monthly and comes as a surprise to workers who only budgeted for year-one deductions.

If your employer provides housing, a monthly deduction of 10,000 to 30,000 JPY is common. This is usually below market rate and is legitimate, but it should be clearly stated in your contract. Total deductions across all categories typically reduce gross pay by 25 to 35 percent.

In Japan's SSW framework, employers are not allowed to charge workers recruitment fees. Costs on the employer side are the employer's responsibility. If a sending organization in your home country charges a service fee, the amount should be disclosed clearly and in advance.

The ILO Dhaka Principles and Japan's own guidelines suggest total worker-paid fees should not exceed one month's expected salary in Japan. Anything significantly above that — especially in a single upfront payment before a visa is confirmed — is a warning sign.

Legitimate costs that workers may reasonably be asked to pay: skills test fees, language test fees, document translation, medical check. Costs that should not come directly from workers: employer-side recruitment fees, large training deposits paid to intermediaries before placement.

When you receive a job offer or placement proposal, ask for a written cost breakdown before signing anything. You should be able to see: gross monthly salary, which deductions apply and at what rates, whether housing is deducted or employer-provided at no cost, and whether any pre-departure fees are your responsibility or the employer's.

A trustworthy offer can answer all of these questions clearly. If the response is vague, incomplete, or changes between conversations, that uncertainty is itself a cost — because unclear finances mean you cannot plan accurately and you may end up spending more than expected.
