Rakuten Communications

Rakuten Communications launched in 2000 as the connective tissue for the Rakuten Group's digital ecosystem, providing broadband, IP telephony, and network infrastructure services. The firm operates under the umbrella of Rakuten Group, the Japanese internet conglomerate founded by Hiroshi Mikitani, and today serves as the operational and technological foundation for Rakuten Mobile's nationwide cellular network. The firm's investment and operational footprint spans physical network infrastructure, software, and telecom services. It builds and maintains mobile network assets across Japan, supports Rakuten Mobile's cloud-native, Open RAN architecture, and runs an MVNE platform that white-labels connectivity for enterprise and consumer MVNO partners. Cybersecurity services and contact-center technology round out a portfolio that bridges hard telecom assets with enterprise software. A cross-border alliance with Telefónica advances joint development of Open RAN technology, while indirect exposure to digital assets comes through the parent group's small ETF positions in iShares Bitcoin Trust and iShares Ethereum Trust (per Altss research). In April 2025, Rakuten Communications integrated its consumer-facing mobile business with Rakuten Mobile, a structural move that consolidated the group's telecom operations under one entity (per the firm, 2025). The firm now focuses on backend infrastructure, wholesale MVNE services, and enterprise solutions, while leadership sits with Kazuhiro Suzuki as CEO and Sharad Sriwastawa as Co-CEO and CTO of the broader mobile and symphony divisions. Philanthropic activity flows through the Rakuten Clutch Special Charity Fund. Rakuten Communications stands out by operating as the infrastructure layer beneath a retail brand, not the retail brand itself — a structure that makes it a corporate investor in hard connectivity assets (spectrum, towers, cloud infrastructure) without the consumer-facing P&L that shapes a traditional telecom. Its business model ties directly to the group's ability to monetize data and loyalty across e-commerce, fintech, and mobile — making the communications unit both a capital sink for network capex and a strategic enabler for Rakuten's broader ecosystem ambitions.
