HND logged 2,586 flights across August 25 and 26, 2025, split almost perfectly between 1,290 arrivals and 1,296 departures. The 511 unique aircraft active over those two days averaged 53.9 movements per hour, with traffic running continuously from midnight through 23:59 JST. The busiest hour was 08:00, when 176 flights operated, 88 arrivals and 88 departures in exact balance. Activity built sharply from a quiet overnight window, with the 03:00 hour recording only 8 total movements, then climbed through the morning and held above 130 movements per hour from 08:00 through 22:00 before tapering again. The Haneda to Osaka Itami corridor was the heaviest single route, with 121 combined movements (60 arrivals, 61 departures). Kansai International added another 48, and Gimpo in Seoul contributed 38. Approach tracks were concentrated from the WSW, accounting for 559 of 1,290 recorded arrival vectors, followed by W at 177 and NNE at 168. Departure headings spread more broadly, with WSW leading at 394, W at 343, and N at 177. Japanese-registered aircraft made up the clear majority of the fleet, 350 of 511 unique aircraft, with Chinese and US registrations next at 46 and 40 respectively. Altitude data across roughly 1.45 million ADS-B position points shows a strong concentration below 1,000 feet (179,040 data points), reflecting the volume of approach and departure activity close to the airport. A secondary concentration clusters between 40,000 and 44,000 feet, consistent with cruise-phase tracking of longer flights. The highest recorded altitude was 47,700 feet, reached by a Chinese-registered aircraft on an arrival covering 1,326 nautical miles. The longest flight in the dataset was a 3,238 nautical mile arrival from Pondok Cabe Air Base lasting 441 minutes, flown by an Iceland-registered aircraft.
