Common Mistakes to Avoid

Skipping METI review — it costs 3x to retrofit
Treating MVP as v1.0 — feature creep blows the budget
Ignoring Japan-specific payment rails and using Stripe-only
No analytics instrumentation at launch — you lose 6 weeks of signal
Monolith when a modular monolith would ship faster and migrate later
Hiring solo freelancers without a PM layer — scope drift guaranteed

FAQ

What does it cost to software validation & testing in japan?

MVP engagements land at ¥2,200,000 - ¥4,800,000; mid-sized builds at ¥4,800,000 - ¥13,000,000; complex enterprise projects at ¥13,000,000+. Final quote depends on integrations, compliance, and platform count.

How long until we ship an MVP?

A competent team delivers a public MVP in 10–14 weeks. Enterprise DX builds with SSO, audit logs, and external audits land at 6–9 months.

Which tech stack do you recommend in Japan?

For mobile-first: React Native or Flutter. For web: Next.js + Node/NestJS or .NET 8. For data: Postgres + Redis. All deployable on AWS/Azure regions local to your customers.

How does METI + PIPC (APPI) affect our build?

METI + PIPC (APPI) mandates data residency, breach notification, and DPIAs. We embed this in architecture (encryption at rest, consent ledger, audit trails) rather than bolting it on later.

Can you augment our existing team?

Yes. Our staff augmentation model plugs senior engineers directly into your Jira/Linear/GitHub. Contracts start at 3 months, renewable monthly.

Who owns the IP?

You do, day one. We sign IP-assignment + NDA before code is written. Japan courts of jurisdiction apply.

Do you work on legacy modernization?

Yes — strangler-fig migrations off .NET Framework, PHP5, and legacy Java are 30% of our book.
