Enterprise Software Development Company in Tokyo

Cost is driven by scope. A focused enterprise application for a Tokyo, Tokyo organisation reaches production in four to six months. Multi-system platforms add integration layers, migration and compliance work, and organisation-wide programmes run several parallel squads across a phased roadmap. Dedicated enterprise teams are also available on a monthly basis. Every engagement is scoped fixed-price or on a capped time-and-materials model after a free architecture review.

Load, longevity and governance. Enterprise systems carry thousands of concurrent users, live for a decade, integrate with a dozen other systems and are audited. That means SSO and granular RBAC from day one, audit trails, HA and disaster recovery design, documented architecture decisions, security review gates and a support model with an SLA behind it. An agency that ships marketing sites is not set up for any of that; we run 200+ developers under SOC 2 Type II and ISO 27001 controls precisely because enterprise buyers require it.

A single well-scoped enterprise application takes four to six months to first production release. Platform programmes covering several business processes run nine to eighteen months, phased so value lands each quarter rather than at the end. We always sequence delivery so a usable slice reaches production early and the rest builds on validated foundations.

Yes — most of our enterprise engagements are co-delivery. We embed squads inside your SDLC, use your repositories, ceremonies, code review standards and security policy, and staff whatever the gap actually is: architects, backend, frontend, QA, DevOps or all of it. With 200+ developers on staff we can scale a team up for a rollout phase and back down afterwards without you carrying the headcount.

Compliance is engineered in, not audited on afterwards. We design to your control framework — SOC 2, ISO 27001, HIPAA, GDPR, PCI-DSS — with encryption at rest and in transit, least-privilege access, immutable audit logging, data classification and residency controls, secrets management and dependency scanning in CI. Penetration testing and an evidence pack for your auditors are part of delivery, and we sign NDAs and DPAs on day one.

Yes, and we strongly prefer not to do big-bang rewrites. We put an API facade in front of the legacy system, then move capabilities behind it one at a time using the strangler pattern, running old and new in parallel with reconciliation until each slice is proven. The business keeps operating throughout, and if a slice misbehaves you roll back that slice rather than the programme.

Yes. Managed support runs against agreed response and resolution SLAs with an on-call rotation, monitoring and incident process, plus a funded enhancement backlog and quarterly roadmap reviews. Support is priced as a retainer scaled to your criticality tier rather than billed reactively per incident.

You do, without exception. Code lands in your repositories, infrastructure in your cloud accounts, and architecture decisions, runbooks and test suites are handed over as deliverables. There is no proprietary framework of ours in the middle and no dependency on us to keep the system running — which, in our experience, is exactly why clients keep choosing to.
