AST SpaceMobile and Rakuten Form Japan Satellite JV Backed by Up to $1 Billion

What happened

AST SpaceMobile and Rakuten proposed a Japanese joint venture to build and operate a satellite network connecting standard smartphones. It is expected to receive up to $1 billion in government support over about three years and targets domestic service by the end of March 2029; some worldwide services remain subject to regulatory approval.

Proposed

Global impact / market context

The government support could help fund satellite deployment, while Rakuten’s 51% stake and AST SpaceMobile’s 49% stake assign ownership between the partners. If the network launches as planned, broader phone coverage and disaster communications could create service opportunities, but execution and regulatory approval remain important uncertainties.

Analyst inference

The proposal links public funding with private investment in a Japan-focused satellite network, and AST SpaceMobile is set to supply the satellites. The business case depends on completing deployment, reaching service by the stated target, and obtaining approval for any worldwide services.

Analyst inference

What to watch

1. Watch for details on the timing and conditions of the proposed government support, which is described as up to 148 billion yen over approximately three years. Analyst inference
2. Track progress toward the planned end-of-March 2029 domestic service target, including satellite deployment and whether the venture confirms its operating timetable. Analyst inference
3. Look for regulatory approval governing services to AST customers worldwide; without it, the venture’s stated service reach may remain limited to Japan. Analyst inference
