Short answer
Kozushima Airport is a compact island-airport day for aviation fans because Tokyo Metropolitan Government’s airport-use rules record an 800m x 25m runway, no ILS, and small-aircraft apron positions for Dornier 228-class aircraft, while the Tokyo Sightseeing Accessibility Guide describes a two-story terminal with an observation deck on the second floor. Build the day around Chofu propeller flights, Kozushima Port, Miura Fishing Port at Tako Bay, village bus, taxi, rental-car, Tenjo-san, Akasaki Promenade, and weather-aware return planning.

Always confirm current details on official airport, airline, ferry, village, tourism, transport, and weather pages before travel.
Why Kozushima works for aviation fans
Kozushima Airport is a small-airport branch where the aircraft, runway, and island plan all matter. Tokyo Metropolitan Government’s airport-use rules record an 800m x 25m runway, three small-aircraft apron berths for Dornier 228-class aircraft, and no ILS facility. The accessibility guide adds that a 19-passenger propeller plane operates between Chofu Aerodrome and Kozushima, with current schedules to be checked on New Central Airservice.
That combination makes Kozushima useful for travelers who want more than a large-airport deck. You are dealing with a small runway, a compact terminal, a weather-sensitive route, and a village where the port, mountain, beach, and lodging choices can change the whole day. Keep aircraft viewing inside the terminal, the official deck, public roads, ports, buses, taxis, and booked rentals. Avoid fence lines, airport service roads, private land, drone flights, and roadside behavior that could disturb local traffic or airport operations.
Start with the terminal and deck
The Tokyo Sightseeing Accessibility Guide describes Kozushima Airport as the island’s sky gateway at the southern tip of the island. It says the terminal is a two-story structure with an observation deck on the second floor, and notes that the first-floor arrival and departure lobby and boarding area are mostly on the same level. Tokyo Metropolitan Government’s airport-services page lists access from Kozushima Port by car in about 15 minutes, free parking for 44 cars, a no-step route from the terminal entrance to the boarding gate, a multipurpose restroom, and one AED.
Use the airport as the first anchor, then decide whether the day should stay flight-focused or branch toward the port, Tenjo-san, Akasaki Promenade, a village walk, hot springs, food, or a starry-sky plan. Do not assume the deck, terminal services, or ground transport will match old information; check the official pages before travel.
Compare Chofu flights with sea routes
The Kozushima Tourist Association says transport reservations should be made on operator websites and warns that services vary by season and may not depart because of weather. It lists Takeshiba routes by high-speed jet ferry and large overnight passenger ship, Atami, Shimoda, and Chofu flights by New Central Airservice in about 45 minutes. The same access guidance tells flight users to check same-day operation and baggage or checked-luggage weight limits.
Port choice matters on Kozushima. The Tokyo Sightseeing Accessibility Guide says sea access can arrive at Kozushima Port or Miura Fishing Port. The tourist association notes that if you arrive at Tako Bay, a village bus can connect with Kozushima Port, with seasonal operation details to be checked on the village site. A flight-and-ferry comparison is a good aviation plan only when both operators, port choice, weather, and lodging movement leave enough spare time.
Choose local movement before arrival
Tokyo Treasure Island Traffic Information lists local options including route bus or sightseeing bus, rental car, taxi, rental bicycle, and rental motorbike. Tokyo Treasure Islands also lists bicycle, motorbike, rental car, bus, and taxi choices. The tourist association recommends early rental-car arrangements because inventory is limited, and it points travelers toward the village bus for movement between major sightseeing spots and ports.
A rental car is the most flexible way to connect Kozushima Airport, Kozushima Port, Miura/Tako Bay, village lodging, Tenjo-san trailheads, Akasaki Promenade, hot springs, and viewpoints. A bus-based plan can work when it follows the current timetable. A taxi plan should include return movement. Bicycles and motorbikes need route, slope, wind, rain, darkness, and luggage caution.
Add one island branch
Kozushima should not be reduced to the runway. Tokyo Treasure Island Traffic Information highlights Tenjo-san and Akasaki Promenade, while Tokyo’s island tourism pages describe Kozushima through spring water, starry skies, Tenjo-san trekking, Akasaki Promenade, diving, snorkeling, and outdoor activities. These are strong branches, but they are not automatic airport add-ons.
For a first airport-area day, choose one branch. A transport branch compares Kozushima Airport, Kozushima Port, and Miura/Tako Bay. A mountain branch goes toward Tenjo-san only with suitable weather, time, gear, and trail conditions. A sea branch uses Akasaki Promenade or snorkeling context only with current ocean conditions and local rules. A low-risk branch stays around the village, port, food, hot springs, and viewpoints.
Simple first-time plan
| Step | What to do | Why it works |
|---|---|---|
| 1 | Check New Central Airservice, airport services, deck access, ferry status, arrival port, village bus, taxi, rental options, Tenjo-san conditions, ocean conditions, and weather | Kozushima plans depend on air, sea, port, road, mountain, and weather conditions |
| 2 | Use the public terminal, second-floor observation deck, 800m runway context, no-ILS note, parking, and small-aircraft context as the aviation anchor | The airport is small, specific, and useful for official aircraft viewing |
| 3 | Choose a movement base: airport, Kozushima Port, Miura/Tako Bay, village bus, taxi, rental-car, bicycle, or motorbike | Local movement shapes the whole day |
| 4 | Add one branch: Tenjo-san, Akasaki Promenade, village walk, hot spring, port logistics, food, viewpoint, or starry-sky plan | One branch keeps the trip resilient |
| 5 | Leave buffers before flight departure, ship boarding, rental return, bus connection, hiking, sunset, fog, wind, and bad-weather changes | Island travel rewards spare time |
Where this fits in the transport hub
Use this as the Kozushima branch of the Japan Transport Fan Travel Guide. It pairs naturally with Niijima, Oshima, Hachijojima, Miyakejima, Haneda, Chofu-related island flights, Fukue, Tsushima, Iki, Tanegashima, Yakushima, and other island-airport guides. Kozushima stands out because a small runway, Chofu propeller flights, two port possibilities, Tenjo-san, Akasaki Promenade, and starry-sky weather can all affect the same travel day.
