Masayoshi Son's Gulfstream lands in Houston after a Tokyo departure, with a San Antonio leg to follow

Masayoshi Son's Gulfstream G650ER, tail N302TR, was tracked departing Tokyo's Narita International Airport on August 13, 2026, and touching down at William P. Hobby Airport in Houston just under 12 hours later, at 02:21 UTC on August 14. The aircraft then repositioned to San Antonio later the same day, suggesting a multi-stop itinerary rather than a simple arrival.

If Masayoshi Son was aboard, the trip would place him in Texas at a moment when SoftBank's $500 billion Stargate AI infrastructure joint venture — a partnership with OpenAI, Oracle, and MGX — is actively scouting locations for massive data centers. Houston's status as a global energy hub and its growing data-center corridor make it a logical stop for discussions about power supply and site selection, though no public meetings have been confirmed.

The San Antonio leg is particularly intriguing: the city hosts a Toyota manufacturing plant, a burgeoning cybersecurity sector, and the University of Texas at San Antonio's AI research programs. SoftBank's portfolio includes stakes in numerous tech and mobility companies, and a visit could involve portfolio oversight or partnership talks. Recent flight history shows 's aircraft primarily shuttling between Tokyo, Taiwan, and various Japanese cities, with occasional trips to Silicon Valley and the Middle East. A Texas detour is unusual but not unprecedented for a businessman whose net worth swings with SoftBank's stock and whose investment reach spans continents.
