Introduction

Remote work has become a global trend after the COVID-19 pandemic, allowing people to work from anywhere without being tied to a specific location. But for overseas foreigners connected with Japanese companies, questions often arise: Do they need a visa? What about social insurance and taxes?

This article provides a comprehensive guide for companies and workers, covering visas, the new Digital Nomad Visa, social insurance obligations, and taxation rules in Japan.

1. Do Overseas Foreign Remote Workers Need a Visa?

In Japan, a visa (status of residence) is required only if a person works and receives remuneration within Japan.

If a company hires a foreigner living overseas for remote work, there is no need to obtain a Japanese visa. However, if the worker travels to Japan for a business trip, they must apply for a Short-term Stay (Business Visa).

2. Business Trips and Short-term Stay Visa

For business trips, a Short-term Stay (Business Visa) is required.

This visa category covers tourism, family/friend visits, and business purposes. For business trips, the “business purpose” category should be chosen.

Permitted lengths of stay: 90 days, 30 days, or 15 days.

3. How to Obtain a Business Visa

Applicants must submit documents to a Japanese embassy or consulate abroad.

Japanese side usually requires:
Inviting organization: A Japanese company or corporation
Guarantor organization: A company taking responsibility for travel and stay expenses

Screening checks:
Criminal record
Credibility of inviting company
Legitimacy of purpose and activities
Specificity of schedule
Guarantor’s ability to cover expenses

If from a visa-exempt country, no business visa is needed.
If denied, reapplication for the same purpose cannot be made within 6 months.

4. When is a Work Visa Required?

A short-term business visa does not allow paid work. Permitted activities include:
Attending meetings, lectures, inspections
Negotiations, contracts, after-sales services, and research

If remuneration is involved—even for one day—a proper work visa (e.g., Engineer / Specialist in Humanities / International Services) is required.

5. Digital Nomad Visa (Since March 2024)

Application Process

Documents include: activity plan, proof of income, medical insurance, and application forms.

6. Social Insurance for Overseas Remote Workers

If a foreigner is employed by a Japanese company, works under its instructions, and is paid by it, they must join Japan’s social insurance.

Health Insurance: Workers pay expenses abroad first, then claim partial reimbursement under the Overseas Medical Expense system.
Nursing Care Insurance: Only applies to 40–65-year-old residents in Japan. Overseas workers are exempt but must file an exemption notice.
Employees’ Pension (Kosei Nenkin): Required unless exempted by a social security agreement with their country.
Workers’ Compensation Insurance: May apply if work-related accidents occur, but cases are examined individually.
Employment Insurance: Not applicable to overseas workers.

7. Taxation Rules

Taxation is based on residency, not nationality.

Non-residents: Income earned abroad is not taxable in Japan.
Residents (incl. permanent residents): All worldwide income, including remote work, is taxable in Japan.

Directors’ Remuneration
Taxable in Japan, subject to withholding.

Employees’ Salary
Taxed in country of residence, unless the worker holds permanent residency in Japan.

Conclusion

Remote work has unlocked opportunities for global hiring. For Japanese companies, this means they can employ talented foreigners without relocation.

Key takeaways:
No visa is required for overseas workers unless they travel to Japan.
Digital Nomad Visa offers new flexibility (but with strict conditions).
Social insurance applies if there is an employment contract with a Japanese entity.
Taxation depends on residency status.

By understanding these rules, companies can leverage global talent effectively and avoid compliance risks.
