Precision language supportfor U.S. government missions in Japan.
J-A Support Co., Ltd. provides translation, interpretation, and consulting between Japanese and English — built around the pace, documentation, and accountability of U.S. military contracting.
Three capabilities. One point of contact.
Every engagement is quoted and delivered by the same team that answers the request — so scope, terminology, and schedule stay in one place instead of being handed between departments.
Technical, legal, and administrative documents, rendered with terminology that holds up to review.
- Japanese ↔ English for technical, legal, and administrative documents
- Terminology control and a shared glossary across a project
- Deliverables in the file formats your office already works in
- Confidential handling of sensitive program material
Consecutive and simultaneous support for meetings, site visits, inspections, and training — on base, on site, or at your facility.
Local knowledge that keeps a program moving — protocol, coordination, and the practical detail that never appears in a statement of work.
Built for the way requirements actually arrive.
We provide specialist support to companies pursuing business with U.S. military facilities across Japan — from bidding and contracting through to the start of the engagement.
Translation is the easy part. What decides a requirement is whether the paperwork, the terminology, and the schedule hold together. We work to that standard.
Requirement response
We read the statement of work, scope the language and liaison tasks, and return a written quotation with assumptions stated plainly.
Document discipline
Deliverables arrive in the agreed format, version-controlled, with a record of what changed between revisions.
Confidentiality
Program material is handled on a need-to-know basis and is never reused, republished, or shared outside the engagement.
A single point of contact
One coordinator owns your request from quotation through delivery and invoicing — no handoffs between departments.
A Japanese company based in Iwakuni, working alongside U.S. contracting officers, program offices, and prime contractors.

Based in Iwakuni. Accountable in two languages.
J-A Support Co., Ltd. is a Japanese company working where U.S. military requirements meet Japanese suppliers, facilities, and authorities. Our work is unglamorous and exact: making sure the right words reach the right people, on time, in a form that stands up to review.
Iwakuni is home to MCAS Iwakuni, and it is our home too. That means local relationships built over time, an understanding of how access, scheduling, and protocol actually work here — and a short distance to the places a requirement needs us to be.
