Labor unions for foreign workers in Japan (including general unions)

A labor union in Japan is open to foreign workers: the Trade Union Act (労働組合法) defines a worker by income, not nationality, and bans employers from firing or punishing you for joining one. A general union (合同労組) takes members from any workplace. If your employer breaks the rules, you can file with the labor commission (労働委員会) within 1 year. All as of October 2026.

This page explains the law and public information. It isn’t legal advice, and we don’t recommend a union. For your case, ask a lawyer (弁護士) or the hotlines below.

Can foreigners join a labor union in Japan?

Yes. The Trade Union Act defines a worker (労働者) as anyone who lives on wages, salary or similar income, whatever the occupation. It sets no nationality test and no visa test. A union’s rules must state that no one can lose membership because of race, religion, sex, family origin or status.

What does the law protect when I join a union?

Article 7 of the Act bans four employer actions, called unfair labor practices (不当労働行為):

A union’s representative may negotiate with the employer for the union and its members. That is the legal basis for collective bargaining (団体交渉).

Where do I complain about an unfair labor practice?

You or your union file a remedy application (救済申立て) with the labor commission (労働委員会) of your prefecture. The labor ministry says the commission examines the case and, if it finds an unfair practice, can order remedies such as reinstatement, back pay or a ban on interfering with the union. The Act says the commission can’t accept a complaint filed more than 1 year after the act, or after a continuing act ended.

What is a general union (合同労組)?

A general union isn’t tied to one company or industry. Two public examples:

• Tozen Union (Zenkoku Ippan Tokyo General Union) says it “does not restrict membership to those working in any one industry, trade or workplace”. Nearly all members are foreign nationals, and most work in banking, language teaching and publishing, mainly in Tokyo, Kanagawa, Saitama, Chiba, Gunma and Tochigi. It is organized into more than 25 chapters (as of May 2024) that negotiate pay and conditions with employers. Its site is in Japanese and English and has a Foreign Workers Handbook.
• General Union in Osaka has an English and Japanese site, a contact form and a consultation page, with an Osaka office and a Fukuoka office mentioned on the site. Its join page recommends asking for a consultation first, especially if you have a workplace problem.

Neither page we read gives dues or visa-specific eligibility, so ask before you apply. These are examples, not recommendations.

Do I need a union to get help?

No. Several free public options exist:

• Labor bureau consultation. The General Labour Consultation Corner (総合労働相談コーナー) gives information and consultation. The bureau director can give advice and guidance, and a Dispute Adjustment Committee can mediate. All are free and confidential, and your employer may not treat you unfavorably for using them.
• Labor commission mediation. One prefectural commission, Chiba, says its services are free and confidential. It mediates collective disputes, and runs mediation for individual disputes, which is the route it points individual workers to. Other prefectures work in a similar way, but check yours.
• Hotlines. English 0570-001-701 (weekdays 10:00 to 15:00, closed noon to 13:00, call charges apply) and the free English hotline 0120-531-401 (weekdays 17:00 to 22:00; weekends and holidays 9:00 to 21:00). Both close from 29 December to 3 January.

Mediation helps both sides compromise rather than forcing a settlement, according to Chiba’s pamphlet (2014). A union is most useful when you want to bargain together with coworkers. See your rights as a foreign worker for unpaid wages and the other free routes.

Should I tell my employer I joined?

We found no official rule on this, so we don’t give advice on it. Ask the union how it handles notice to employers before you join.
