Registered support organizations: role, fees & how to choose

By: Watari Editorial Team·Last updated: 2026-07-01

A registered support organization (RSO) carries out, on behalf of an employer, the support that Specified Skilled Worker (i) foreign nationals need to work and live in Japan. RSOs are registered with the Immigration Services Agency; over 11,000 are registered nationwide as of 2026.

What is a registered support organization?

Employers hiring under SSW (i) must create and carry out a support plan covering work, daily and social life. An RSO is the body an employer can fully outsource this support to.

Core (mandatory) support duties

Pre-arrival guidance, airport pick-up/drop-off, housing and contracts, life orientation, accompanying to public procedures, Japanese-language opportunities, consultation and grievance handling, promoting exchange with locals, job-change support on involuntary termination, and periodic interviews/reporting — provided in a language the worker understands.

Typical fees

Monthly support commissions are commonly around JPY 20,000–30,000, sometimes with an initial fee. Amounts vary by organization, region and scope.

Difference from supervising organizations & agencies

Supervising organizations oversee Technical Intern / Skill Development placements and are legally distinct from RSOs. Recruitment agencies introduce candidates but do not carry out support.

How to choose — checklist

Languages supported, coverage area and offices, track record, fee transparency, emergency support, and registration number. For Cambodian workers, Khmer-language support matters. On Watari you can search by prefecture and language.
