U-NEXT CO., LTD. Tech Stack

Japanese SVOD and MVNO operator with video, manga, music, and telecom services

Entertainment Providers Shinagawa-ku, Tokyo 201–500 employees Founded 2007 Public Company

U-NEXT operates Japan's second-largest video-on-demand service alongside a mobile MVNO business, built on a polyglot stack (Go, TypeScript, Kotlin, Swift) with deep iOS/Android native implementations. The tech footprint—iOS-first tooling (Xcode, UIKit, SwiftUI, StoreKit), Kubernetes orchestration, and distributed storage (TiDB, Ceph, Redis)—reflects a consumer app-first architecture. Active projects in core system development, infrastructure monitoring, and anime production sit alongside persistent technical debt and legacy system maintenance challenges, indicating a maturing platform dealing with scaling pressures across streaming and telecom infrastructure.
