Quick Answer
For most travelers, the best way to get from Kagoshima Airport (KOJ) to Yakushima Island is a combined route using a local bus to Kagoshima Port, then a high-speed ferry. This is the most cost-effective and direct public transport option. The total journey takes approximately 3 to 4 hours (30 min bus + 2-3 hour ferry) and costs around ¥8,000 to ¥13,000 one-way, depending on the ferry type (Toppy or Rocket). The key transfer point is Kagoshima Port (Kagoshima-kō).
Overview: Reaching Japan's Mystical Island
Yakushima, a UNESCO World Heritage site famous for its ancient cedar forests (like Jomon Sugi), is accessible via Kagoshima Airport (KOJ). There is no direct bridge or tunnel, and no direct flights from KOJ to Yakushima (KUM). All routes require a transfer in Kagoshima City. Your choice depends on budget, time, and travel style.
How to Choose Your Route:
- For Budget & Scenery: Take the bus from the airport to Kagoshima Port, then the high-speed ferry. This is the standard route.
- For Speed & Convenience (Higher Budget): Fly from KOJ to Yakushima Airport (KUM) via a connecting flight from Fukuoka or Osaka, or take a direct flight from other major cities.
- For Maximum Flexibility on Yakushima: Rent a car at KOJ, drive to the port, and ferry it over to the island.
Option 1: Bus + High-Speed Ferry (Most Recommended & Economical)
This is the most common and straightforward public transportation route. It involves a short bus ride from the airport to the ferry terminal, followed by a scenic voyage across the sea to Yakushima.
Step-by-Step Guide:
- Airport to Kagoshima Port: Upon exiting Kagoshima Airport arrivals, board the “Kagoshima Kotsu City Bus” bound for “Kagoshima Chuo Station” or “Kagoshima Port (Ferry Terminal)”. The ride takes about 30-40 minutes and costs ¥630. Buses are frequent (every 10-20 mins).
- Ferry from Kagoshima Port to Yakushima: Two companies operate high-speed ferries:
- Toppy / Rocket (by Yakushima Ferry): 2 to 2.5 hours. Costs ~¥7,500 (Toppy) to ¥9,500 (Rocket) one-way.
- Yakushima 2 (by Tane Yaku Jet Ferry): About 2 hours. Costs ~¥8,000 one-way.
- Arrival in Yakushima: Ferries arrive at either Miyanoura Port (main port with most bus connections) or Anbo Port. Check your accommodation location to choose the right port.
Deep Dive: Ferry Types & Experience
The “Rocket” is the newest and fastest ferry (hydrofoil), offering slightly more legroom and stability in mild waves. The “Toppy” is a catamaran, also fast and reliable. Both have airplane-style seating, vending machines, and large windows for ocean views. Seas can be rough; consider seasickness medication if prone.
Option 2: Domestic Flight (Fastest, But Requires Connection)
While there is no direct flight from Kagoshima Airport (KOJ) to Yakushima (KUM), you can fly if you route through another Japanese city. This is about speed, not convenience from KOJ itself.
How It Works & Total Door-to-Door Time:
You would need to: 1. Fly from KOJ to a hub like Fukuoka (FUK) or Osaka (ITM/KIX) (50-80 min flight). 2. Connect to a direct flight to Yakushima Airport (KUM) from that hub (60-90 min flight). 3. Add airport transfer, check-in, and security times (2-3 hours). Total “door-to-door” time from KOJ to your Yakushima hotel can still be 5-7 hours, often longer and much more expensive than the ferry option. This method is only recommended if your international flight lands directly in Fukuoka/Osaka and you book a through-ticket to KUM.
Key Airlines & Routes:
- JAC (Japan Air Commuter): Operates most flights to Yakushima from Kagoshima *City* (not the airport), Fukuoka, and Osaka.
- ANA: Has codeshare flights from major cities.
Important: Yakushima Airport (KUM) is small. Rented cars, buses, and taxis are available for transfer to your final destination, which adds more time and cost.
Option 3: Rental Car + Ferry (For Maximum Island Flexibility)
Ideal for families, groups, or those wanting to explore Yakushima's remote trails and beaches at their own pace without relying on the infrequent island buses.
The Process:
- Rent a Car at Kagoshima Airport: Major companies (Toyota, Nippon, Times) have counters at KOJ. Book well in advance. Average cost: ¥6,000 - ¥12,000 per day.
- Drive to Kagoshima Port: A 30-40 minute drive via the Kyushu Expressway (toll ~¥500) or local roads.
- Ferry the Car to Yakushima: You must book a space for your vehicle on the car ferry (Yakushima Ferry). The voyage takes about 4 hours. Costs vary:
Vehicle space is limited; reservation is mandatory months ahead for peak seasons.Item One-Way Cost (Approx.) Standard Car Fee ¥13,000 - ¥18,000 Driver's Passenger Ticket ¥5,200 Additional Adult Passenger ¥5,200
Is It Worth It?
For a 3+ day stay on Yakushima with a group of 3-4 people, the convenience often outweighs the high ferry cost for the car. It saves time waiting for buses and allows access to early-morning hiking trails. For solo or couple travelers on a budget, it's rarely economical.

Traveler Tips & Essential Advice
Luggage Solutions:
If you have large suitcases and plan to hike, use Japan's excellent “Takkyubin” (luggage forwarding) service like Yamato Transport. You can send your main luggage from Kagoshima Airport directly to your Yakushima hotel (takes 1-2 days), allowing you to travel to the ferry with just a daypack. Cost: ¥2,000-¥3,000 per item.
Booking Strategy:
Ferry tickets can sell out during peak travel periods (late April-early May, July-August, October). Book online as soon as your travel dates are fixed. For car ferries, book monthsin advance.
On Yakushima Transport:
Public buses on the island are infrequent and stop early. If you didn't bring a car, consider renting a car, scooter, or booking a taxi tour on the island itself. Rental car agencies are at both ports and the airport.
Weather Contingency:
Ferries are canceled in case of typhoons or very rough seas. Always build a flexible buffer day into your itinerary, especially when flying out of Kagoshima after your island trip. Travel insurance is recommended.
