Masayoshi Son flies home to Tokyo after a week of AI dealmaking in the Gulf

Masayoshi Son landed at Tokyo Haneda on May 29 aboard his Gulfstream G650ER, N302TR, after a short flight from an oceanic position east of Japan. The trip capped a week of transcontinental travel that saw Son fly from Tokyo to Hawaii on May 22, then on toward the Gulf region on May 28, per flight data.

The same week, Son was engaged in high-stakes moves tied to the $500 billion Stargate AI infrastructure joint venture with OpenAI, Oracle, and MGX. The Financial Times reported on May 27 that SoftBank was in advanced talks with Saudi Arabia's Public Investment Fund to secure additional financing for the project. Son also met with UAE officials in Abu Dhabi regarding Stargate data-center investments, as covered by Bloomberg on May 28. This pattern of shuttling between Tokyo, the Middle East, and the US underscores his role as the prime fundraiser and face of the venture.

This return to Haneda is a routine home base turn for Son, who keeps a mansion in Tokyo's Minato ward. After a whirlwind of transoceanic dealmaking, the short final leg from the open Pacific suggests a layover or refueling stop after crossing the Middle East — a commute as familiar to Son as the quarterly SoftBank earnings call.
