- Rakuten and AST SpaceMobile's RAST won Japan's J-LEO 'domestic Starlink' program
- The goal is direct-to-phone LEO satellite coverage for islands, mountains and disasters
- Toyo Keizai flags technical capacity, funding burn and commercialization as open hurdles
Japan's 'domestic Starlink' — the J-LEO low-earth-orbit program under the communications ministry — went to RAST, the Rakuten-AST SpaceMobile alliance, with roughly 150 billion yen in subsidies to bring direct-to-phone satellite coverage to islands, mountains and disaster zones. Toyo Keizai flags three hurdles: direct-to-phone bandwidth still promises 'connected' rather than 'fast'; AST's satellite production and launch cadence burns heavy cash while Rakuten's own finances stay under scrutiny; and low user density means the business leans on government procurement and wholesale roaming, not retail subscriptions — all while KDDI already offers Starlink direct service. Sovereignty and resilience are the differentiators; Taiwan, with its own island-communications problem, should watch this experiment closely.
