Japan approves up to $912 million grant for Rakuten‑AST SpaceMobile satellite network

Japan’s government announced on Tuesday that it will provide a grant of up to $912 million to a satellite venture led by e‑commerce giant Rakuten and U.S. firm AST SpaceMobile. The funding is intended to accelerate the development of a low‑Earth‑orbit (LEO) broadband network that can deliver mobile internet directly to smartphones, positioning Japan to challenge the dominance of SpaceX’s Starlink service.

Core developments

According to a Reuters report, the Ministry of Economy, Trade and Industry (METI) will allocate the grant in stages, contingent on the project meeting specific milestones. The total amount could reach $912 million, making it the largest single government subsidy for a private satellite initiative in Japan to date. Reuters

Yahoo Finance echoed the figure, noting that the grant will be used to finance the construction of the satellite constellation, ground infrastructure, and the integration of the network with Rakuten’s existing mobile services. Yahoo Finance

Mobile World Live highlighted that the partnership, branded as the Rakuten‑AST SpaceMobile Satellite Network, will leverage AST SpaceMobile’s patented “direct‑to‑handset” technology, which allows standard smartphones to connect to LEO satellites without the need for a ground terminal.

Why it matters

The grant marks a decisive step for Japan to develop a home‑grown LEO broadband ecosystem. By enabling direct satellite connectivity to mobile phones, the network could extend high‑speed internet to remote islands, mountainous regions, and disaster‑prone areas where terrestrial infrastructure is vulnerable. This aligns with Japan’s broader “Society 5.0” vision of integrating advanced digital services into everyday life.

Strategically, the project reduces Japan’s reliance on foreign satellite operators for critical communications. In the wake of heightened geopolitical tensions in the Indo‑Pacific, having an indigenous satellite broadband capability is viewed as a safeguard against potential service disruptions or security breaches. finance.biggo.com

Economically, the initiative could stimulate domestic aerospace manufacturing, create high‑skill jobs, and foster a supply chain that includes Japanese satellite component makers. Analysts cited by Yahoo Finance anticipate that the project could generate ancillary revenue streams for Rakuten’s mobile carrier, Rakuten Mobile, by offering bundled data plans that tap into the satellite layer.

From a market‑competition standpoint, the venture directly challenges SpaceX’s Starlink, which already provides coverage over Japan and has secured contracts with the Japanese Self‑Defense Forces. By offering a locally controlled alternative, the Rakuten‑AST network could attract government contracts, corporate customers, and consumers wary of foreign data routing. finance.biggo.com

Differing viewpoints

Government officials, as reported by Reuters, framed the grant as a “strategic investment” to ensure Japan’s technological independence and to spur innovation in the satellite sector. They emphasized that the funding would be performance‑based, with METI monitoring progress against a detailed roadmap.

Industry observers expressed cautious optimism. Mobile World Live noted that while the direct‑to‑handset technology holds promise, it remains unproven at scale, and the timeline for full commercial rollout could extend several years beyond the initial funding period.

Investors, on the other hand, displayed a more tempered reaction. The Yahoo Finance piece on ASTS stock highlighted that the grant announcement halted a recent decline but left lingering concerns about the venture’s capital intensity and the competitive pressure from well‑established players like Starlink and OneWeb.

Critics, not directly quoted in the sources but reflected in commentary from finance.biggo.com, warned that government subsidies could create market distortions, potentially crowding out smaller domestic startups that lack comparable financial backing.

What’s next

The grant will be disbursed in tranches linked to milestone achievements, starting with the design and construction of the first batch of satellites slated for launch in late 2027. METI will conduct quarterly reviews to assess technical progress, cost adherence, and regulatory compliance.

Rakuten and AST SpaceMobile plan to file detailed technical specifications with Japan’s Radio Regulatory Authority by the end of the year, a prerequisite for acquiring the necessary frequency allocations for LEO operations.

Following the initial launch phase, the partners aim to commence limited beta services on Rakuten Mobile’s network in early 2029, targeting remote prefectures such as Okinawa and Hokkaido. Full commercial rollout is projected for 2030, contingent on successful integration of the satellite layer with existing 5G infrastructure.

Investors will be watching the next quarterly earnings reports from both Rakuten and AST SpaceMobile for updates on capital expenditures and any additional public‑private financing that may be pursued to expand the constellation beyond the first phase.
