Masayoshi Son returns to Tokyo after European detour on G650ER.

Masayoshi Son, the visionary behind SoftBank Group's sprawling investments, touched down at Tokyo's coordinates early Thursday aboard his Gulfstream G650ER, N302TR. The 12-hour flight from Keflavik, Iceland, followed a stopover after departing Rome, tracing a circuitous path back to his home base at Narita International. With a top speed of 526 knots and cruising at 47,000 feet, the jet embodies the efficiency of Son's global mobility, a staple for the man steering Japan's richest fortune estimated at $49 billion to $71 billion.

This return aligns with Son's recurring Tokyo-centric operations, where he oversees SoftBank from his Minato mansion, complete with its bespoke weather-simulating golf range. Frequent jaunts to Silicon Valley for Woodside estate visits and investment talks give way here to domestic priorities, including the upcoming earnings briefing on May 13. Son's 2025 pledges of $100 billion in U.S. AI infrastructure, via the Stargate joint venture with OpenAI, Oracle, and MGX, underscore his trans-Pacific focus, even as European stops hint at broadening Arm Holdings dealings or UK ties.

Son's net worth has weathered dramatic swings—from a $5 billion deficit to triple-digit gains—mirroring SoftBank's volatile stakes in Arm and AI bets. As chairman owning a third of the company, his Iceland-to-Tokyo leg closes a chapter on what may have been Vatican-adjacent meetings in Rome or strategic refueling. Back in Tokyo, expect the 65-year-old to pivot toward Taiwan routes or Saudi ventures, ever chasing the next tech horizon with wry persistence.
