Ignited Nepal builds full-stack web applications for Japanese enterprises and B2B SaaS companies where a CMS is not the right tool. React and Next.js front-ends, Node.js or Python back-ends, database design, API development, authentication compliant with the Act on the Protection of Personal Information (APPI), and cloud infrastructure on AWS Tokyo region (ap-northeast-1) for data residency. Built for enterprise internal tools, B2B SaaS products, booking and appointment systems, and the operational platforms that Japanese businesses run on.
Your team manages a critical operational process through a combination of spreadsheets, legacy systems, and manual workflows that have accumulated over years. The process is understood by the people who run it but is not in a system that makes it auditable, scalable, or transferable. You need a custom internal application with a proper data model, a user interface designed for your operators, role-based access control, and the audit trail that enterprise compliance requires.
You have a product concept for the Japanese B2B market that requires multi-tenant architecture, subscription management, role-based access, and data handling that complies with APPI. You need a development partner who understands how to build SaaS products that meet the expectations of Japanese enterprise buyers: reliability, security documentation, data residency in Japan, and the operational predictability that large organisations require before they adopt a new platform.
You operate a service that requires booking, scheduling, or appointment management at a level of complexity that generic booking software does not support. Your rules for availability, resource allocation, conflict resolution, cancellation, and notification are specific to your operation. A custom booking system built around your actual rules is a different product from a generic booking tool with your rules bolted on.
You launched on a CMS, a no-code tool, or an off-the-shelf platform and the platform is now a constraint on what you can build. Every new requirement is a workaround, the integrations you need are not supported, and your data is locked in a structure that the platform owns. You need a ground-up build on a stack you control.
Critical business processes managed in spreadsheets, email, and disconnected tools are fragile in proportion to how important they are. The data exists across multiple sources, is not authoritative anywhere, and requires manual reconciliation to produce anything useful. An application built around the actual data model of the process replaces fragility with structure, and manual reconciliation with reliable reporting.
The Act on the Protection of Personal Information requires explicit decisions about how personal data is collected, stored, used, and deleted. For custom applications handling Japanese user data, these decisions must be made at the architecture level: where data is stored, how it is encrypted, what the retention and deletion policy is, how data subjects can exercise their rights, and what the audit trail records. Applications built quickly without these decisions produce compliance obligations that are expensive to address after launch.
When the features you need require workarounds in the platform you chose, when performance is limited by platform architecture rather than your application logic, and when every customisation requires a plugin that creates the next dependency, the platform is costing you more than it is saving. The point at which a custom build is more cost-effective than continued platform workarounds is earlier than most organisations expect.
Japanese enterprise buyers and government-adjacent organisations increasingly require that application data be stored in Japan. AWS Tokyo region (ap-northeast-1) satisfies this requirement for applications built on AWS infrastructure, but it must be a deliberate architecture decision, not an afterthought. Applications that do not have explicit data residency configuration cannot credibly claim Japanese data residency to enterprise customers or regulators.
We produce a full technical specification before development begins: data model, entity relationships, user roles and permissions, API design, third-party integration plan, authentication and APPI compliance approach, and infrastructure architecture on AWS Tokyo region. The specification is reviewed and approved by your team and becomes the reference document for the project and the primary handover documentation.
We build the front-end in React with Next.js and TypeScript. The front-end is built to the technical specification, designed for the actual users of the application including Japanese-language UI text and any bilingual Japanese/English interface requirements, and tested for performance and correctness across the browsers and devices your users will access it on.
We build the back-end in Node.js with Express or NestJS, or in Python with FastAPI or Django, depending on your requirements. The back-end exposes a clean, documented API, implements the business logic defined in the specification, and handles the processing, queuing, and storage requirements of your application. For booking and appointment systems, the scheduling and conflict resolution logic is implemented at the back-end layer, not in front-end code.
We design the database schema from your data model, with indexing strategy and query optimisation matched to your expected data volumes and query patterns. PostgreSQL for relational data, MongoDB for document-oriented data, or a combination where the use case calls for it. Schema design is documented as part of the technical specification and updated throughout development.
We build a documented, versioned API that exposes your application's capabilities to the front-end and to any third-party integrations or future client applications. For enterprise applications, API documentation is maintained throughout the project and is part of the handover package.
We implement authentication appropriate to your application and compliant with APPI requirements for personal data: secure session handling, SSO integration for enterprise environments where required, multi-factor authentication, role-based access control, audit logging of data access and modifications, and data handling practices that satisfy the collection, use, and deletion requirements of APPI. For applications subject to notification obligations, we document the data flows and retention policy as part of the specification.
We provision and configure infrastructure on AWS ap-northeast-1 (Tokyo) for data residency in Japan. Infrastructure is provisioned as code, with separate staging and production environments, automated deployments, monitoring and alerting, and backup configuration. Infrastructure documentation is part of the handover package.
We set up staging and production environments with a CI/CD pipeline from the project's start. All changes are validated on staging before reaching production. Deployment is automated and documented. Environment-specific configuration and secrets management are handled correctly from the first deployment.
We write unit tests for business logic, integration tests for API endpoints, and end-to-end tests for critical user flows. Technical documentation covers the architecture, API, database schema, infrastructure, and deployment process. Handover includes a documentation package and walkthrough session with your team.
We work with your team to understand the process the application will serve, the users it will support, the data it will handle, and the integrations it requires. We identify APPI compliance requirements, data residency needs, and the performance expectations of your user base in Japan. We produce a project scope document for your approval before the specification work begins.
We produce the full technical specification: data model, entity relationships, API design, authentication and APPI compliance approach, third-party integration plan, and infrastructure architecture on AWS ap-northeast-1. The specification is reviewed and approved before development begins. Scope changes after this point are managed as formal change requests.
We build front-end and back-end in parallel sprints, with working software demonstrated at the end of each sprint. Staging is live from the first sprint. You test real functionality against real data throughout the project, not only at the end.
We complete all third-party integrations, run the full test suite, and conduct a security review covering authentication, authorisation, injection vulnerabilities, data exposure, and APPI compliance for personal data handling. All issues are resolved before production launch.
We run a full validation cycle on staging with your team before production launch. Production infrastructure on AWS Tokyo is provisioned, monitoring and alerting are live, and the deployment is made with a rollback plan in place. We remain available for four weeks after launch for issues that arise in production.
We deliver the full technical documentation package in English and, for core operational documentation, Japanese where required by your team. We conduct a walkthrough session and hand over all credentials, infrastructure access, and codebase ownership.
The Act on the Protection of Personal Information requires that organisations handling personal data of Japanese residents make explicit decisions about the purpose of collection, the scope of use, retention and deletion policies, data subject rights including access and correction, and the technical measures protecting stored data. For a custom application, these decisions are made at the specification stage: data is stored in AWS ap-northeast-1 for Japanese data residency, encryption at rest and in transit is configured explicitly, audit logging records data access and modification, and user rights management is built into the application rather than handled manually. Applications that do not make these decisions at the architecture stage accumulate APPI obligations that are expensive to address after launch.
AWS ap-northeast-1, the Tokyo region, provides low-latency access for users in Japan and satisfies Japanese data residency expectations for enterprise and government-adjacent buyers who require that personal data remain in Japan. For B2B SaaS products targeting Japanese enterprise customers, data residency in Japan is increasingly a procurement requirement. We document the data residency configuration as part of the technical specification so you can present it to enterprise customers and compliance stakeholders.
Internationalisation in a React application is implemented via a library such as i18next or react-intl, with translation keys defined at the component level and translation files maintained separately from the application code. This approach means UI text is managed as a content concern, not a code change. For applications where the Japanese and English interfaces differ in layout rather than just text, we address those layout differences in the component design during the specification stage, since Japanese text density and line length conventions differ from English and can affect component sizing and proportion.
We price on a fixed-fee basis against a technical specification. The specification defines the full scope before development begins. Fixed-fee pricing means the cost is agreed before work starts and scope changes are managed explicitly as formal change requests. For Japanese enterprise procurement processes that require detailed cost breakdowns and scope documentation, the technical specification provides the evidence base for the cost.
A focused internal tool or B2B SaaS product with a clean data model and no complex third-party integrations typically runs twelve to eighteen weeks from approved specification to production launch on AWS ap-northeast-1. A multi-tenant SaaS product with enterprise SSO, complex scheduling logic, and multiple user-facing surfaces typically runs twenty to thirty weeks. We give you a fixed timeline at the end of the specification step.
Not a black box. Real specialists you can call, with their names on the work.
Custom web applications for the Japanese market require deliberate decisions about data residency in AWS Tokyo, APPI-compliant data handling, and infrastructure that enterprise procurement teams can evaluate. We make those decisions at the specification stage, build to the specification, and hand over a codebase and infrastructure your team owns. Send us your brief.
