Masayoshi Son's Gulfstream G650ER, tail N302TR, flew from Tokyo Haneda International Airport to Narita International Airport on Wednesday, October 28, 2026. The aircraft departed Haneda at 06:17 UTC and landed at Narita at 06:52 UTC, spending 35 minutes in the air. The great-circle distance between the two airports is 31 nautical miles, or 36 miles. The flight reached a top ground speed of 292 knots and a highest altitude of 5,900 feet.

The aircraft is a 2017 model with serial number 6259. Its average ground speed on this flight was 53 knots. Haneda's longest runway is 11,024 feet, while Narita's longest runway is 13,123 feet. The elevation at Haneda is 35 feet and at Narita is 141 feet.

The Gulfstream G650ER is an ultra-long-range jet built for trips of up to 7,500 nautical miles. It typically seats 12 passengers and can accommodate up to 19. The aircraft has a top speed of Mach 0.925 and a ceiling of 51,000 feet. Celebplanes estimates the flight burned about 275 US gallons of fuel and produced about 2,644 kilograms of CO2, roughly the same as driving a car 6,544 miles.

This was the 10th tracked landing at Narita for N302TR in the past five months, and the first since September 22, 2026, a gap of 36 days. Narita is Masayoshi Son's home base on file. In the 30 days before this flight, the aircraft visited eight airports in six countries and flew about 20,653 nautical miles. The longest leg in that period was a 4,850-nautical-mile flight from San Diego to Tokyo on October 25. A CITIC Group Boeing Business Jet landed at Narita about nine hours before this flight.

In the 30 days before this flight, the aircraft completed seven flights, spending 43.9 hours in the air. Celebplanes estimates those flights produced about 198,193 kilograms of CO2. The plane had been on the ground for about three days before this trip, following a tracked landing at Tokyo on October 25.

Masayoshi Son is the founder, chairman, and CEO of SoftBank Group, and was Japan's richest person in 2025 with a net worth between $49.3 billion and $71 billion. He is chairman of the $500 billion Stargate AI infrastructure joint venture with OpenAI, Oracle, and MGX. SoftBank owns about 90% of Arm Holdings. Son owns a mansion in Tokyo's Minato ward valued at $50 million to $85 million and a Woodside, California estate purchased in 2012 for $117.5 million. His aircraft frequently travels between Tokyo and Silicon Valley for investment meetings.

Masayoshi Son owns about one-third of SoftBank shares, totaling more than 426 million shares. He owed SoftBank $5.1 billion as of February 2023. His net worth swung from negative $5 billion in a single day to a gain of 248 percent across 2025.

The flight is a short repositioning between two Tokyo-area airports. It follows a pattern of heavy use of N302TR for trans-Pacific and regional travel. The aircraft remains at its home base at Narita.
