Why the Gulfstream IV / IV-SP / G400 Fits Japan

With 4,220 nautical miles of published range, it can fly between Tokyo and destinations such as Shanghai, Manila and Honolulu, allowing for reserves and routing. August and September are the peak typhoon months, so departures in that stretch are planned against the latest forecast.

Jets of this size usually arrive in Japan at Tokyo’s Haneda or Narita, or at Kansai for Osaka and Kyoto, and private-jet slots at Haneda are scarce, so we often plan Narita as well. Runway needs are calculated by the operator for that day’s conditions, and we confirm them with the operator before the trip is booked.

How Japan Clients Use the Gulfstream IV / IV-SP / G400

When the passenger list reaches double figures, as it does for executive tours of Asia and many wedding parties, the heavy jet becomes the natural choice.

Tell your advisor the cities on the itinerary, the passenger count and how much everyone is packing, and you will get a straight view on whether this aircraft fits the trip.
