The same providers serve Nagasaki as serve the rest of Nagasaki 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. Non-technical founders and overloaded engineering leads both end up hiring on gut feel. We provide senior engineers who run structured technical interviews, score against the role you are actually filling, and give a written recommendation you can defend.. The comparison below is about scope and accountability rather than raw capability, because that is where quotes in this category actually differ.
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 Nagasaki: engineers work Nagasaki 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: Dedicated teams at lower cost with European management
Trade-off: Asia-Pacific hours require deliberate overlap planning
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: Filling specific engineering gaps quickly
Trade-off: Smaller bench than the large services firms
Best for: Mixed engagements combining build and staffing
Trade-off: Breadth over specialization in any single stack
Best for: Consumer products needing Japanese market fluency
Trade-off: Agency engagement model rather than engineer placement
Best for: Japan-based contract engineers in major metros
Trade-off: Onshore rates, and the shortlist depends on local market supply
Best for: Long-running product teams with EU working hours
Trade-off: Engagements are team-shaped rather than individual placements
Best for: Japan teams that need same-time-zone engineers
Trade-off: Supply concentrated in the Americas
Best for: Contract and permanent placement through a traditional agency
Trade-off: Placement fees and a slower process than a vetted marketplace
Best for: Startups scaling engineering after a raise
Trade-off: Positioned for funded companies, priced accordingly
Start with scope, because that is where quotes diverge. A credible technical interview engagement names what is included: role-specific interview design, structured technical interviews run by senior engineers, take-home or pair-programming assessment review. Anything missing from the proposal will appear later as a change request, and comparing two quotes that cover different ground is how buyers pick the expensive one by accident.
Then check the exit. If you are hiring one person once, this is often overkill. It pays off when you are building a pipeline and want the bar to stay constant. A provider willing to tell you that before signing is describing the same honesty you will need when something goes wrong mid-engagement.
Red flags that should end the conversation
A structured technical interview runs 60 to 90 minutes, with the scorecard delivered same day.
That is the usual case. We match the interviewer to the stack so the questions test real capability rather than trivia.
