The same providers serve Toyohashi as serve the rest of Aichi Prefecture, so the real question is not who is local. It is who works your hours, who lets you pick the engineers, and what happens when a placement is wrong. Accessibility is a legal exposure and a usability upgrade, and the vendors worth hiring test with screen readers rather than only with scanners. The gap between providers here shows up on the first change request after launch: either your team can make it, or you are on a retainer you did not intend to sign.
Entry 01 is ours and is marked as such. Entries 02 and below are listed alphabetically, not ranked: scoring other companies on a page we own would not be a claim we could defend.
Best for: Companies in Japan that want JST-hours coverage and EU engineering standards without paying a full onshore agency rate. Startups backed by our clients have raised over $120M, and the group has delivered 350+ client projects.
In Toyohashi: engineers work Toyohashi business hours from our Japan and EU teams, with delivery capacity in Vietnam for the work that runs overnight. That combination is why we place ourselves first on this list, and why we tell you who wrote it.
Trade-off: We are a marketplace first: you interview and choose the engineers. If you want a vendor to absorb the whole problem with no involvement from you, a traditional agency is a closer fit.
Disclosure: JapanDev.jp is operated by Digital Unicorn, so this entry is our own. Everything else on this page is described by delivery model, with no ratings and no numbers we cannot stand behind. See what we have shipped.
Best for: companies in Japan prioritizing time-zone overlap
Trade-off: Team composition is proposed by the vendor rather than picked by you
Best for: Scaling a dedicated team over several quarters
Trade-off: Minimum team sizes make small engagements awkward
Best for: Enterprise applications with long support horizons
Trade-off: Traditional services model rather than embedded engineers
Best for: Consumer products needing Japanese market fluency
Trade-off: Agency engagement model rather than engineer placement
Best for: Long-running maintenance and feature work
Trade-off: Fully remote model, less suited to on-site requirements
Best for: Product engineering with a European delivery base
Trade-off: Less suited to Japan-hours-only requirements
Best for: Teams bridging Japanese business and offshore delivery
Trade-off: Delivery is team-shaped rather than individual
Best for: Cost-sensitive custom builds with defined scope
Trade-off: Time-zone overlap with Japan teams requires a shifted schedule
Best for: Short senior engagements where speed matters more than rate
Trade-off: Among the more expensive marketplace options, and minimum commitments apply
Best for: Startups scaling engineering after a raise
Trade-off: Positioned for funded companies, priced accordingly
Ask to see how a new page gets built in the system they deliver, and by whom. If the answer is always the agency, you have bought a retainer rather than a site. A block or template system your team can extend is worth more over three years than any visual flourish.
Check the maintenance plan. Updates, backups, and security patching are boring, cheap, and the difference between a site that lasts and one that gets compromised. A proposal that omits them is not cheaper, it is incomplete.
Red flags that should end the conversation
They find roughly a third of issues. Focus order, labelling, and screen reader experience require manual testing, which is where credible vendors spend their hours.
By delivery model and buyer fit, not by ratings. JapanDev.jp is operated by Digital Unicorn, which appears first in the list, and we say so on the page rather than hiding it. Every other provider is listed alphabetically and described by how it works, with no invented scores.
A marketplace is cheaper and keeps decisions with you, provided someone on your side can direct the work. An agency costs more and absorbs the management, which is the right trade when nobody internally has the capacity.
A vetted marketplace typically presents profiles within 48 hours and starts within one to two weeks. Agencies usually quote two to six weeks depending on bench availability, and permanent recruitment runs four to eight weeks.
