Japan Mobile App Development Partner for Growing Teams
Launch iOS/Android or Flutter/React Native apps with LINE login and messaging, analytics-ready onboarding, and in-app payments that support carrier billing and konbini flows—designed for Japan’s high mobile UX bar.
Will your app support LINE flows and local payments?
In Japan, LINE is often the first touchpoint, and many users expect familiar payment options like carrier billing or konbini-style settlement when they can’t or won’t use cards. We design and build iOS/Android apps (native, Flutter, or React Native), plus admin dashboards and analytics events that make onboarding measurable in Japanese. We also handle store launch assets and app review preparation with Japan-ready metadata.

Application Development — FAQ
1. Can you manage iOS/Android store launches for the Japan storefront?
We prepare builds, screenshots, and Japanese/English store metadata, and guide submission for the Japan App Store and Google Play. Pricing and invoices are in JPY. We coordinate review cycles during Mon–Fri, 9am–6pm JST.
2. Do you build with React Native or Flutter for Japan users, or recommend native?
We do both. For MVPs and shared codebases, React Native/Flutter works well; for highly performance-sensitive features, native may be better. We’ll review device targets and UX expectations and plan sprints around JST overlap on Zoom/Meet.
3. How long does it take to build a mobile app?
A small MVP typically ships in 40–45 days; medium apps in 8–10 weeks; enterprise builds are scoped individually with milestone-based delivery.
4. Do you build for both Android and iOS?
Yes. We use Flutter for cross-platform delivery and native Kotlin/Swift where performance or platform APIs demand it.
5. Who owns the source code?
You do. Full source code, store accounts and cloud infrastructure are handed over on final payment.
