Running with Scenic Views on Aka Island

Only 50 minutes from Naha. As the vessel approaches the port, the emerald-green sea of unbelievable transparency comes into view, leaving you wondering if this is really Japan at all.
Aka Island offers a “miraculous environment” for runners: perfectly paved, easy-to-run roads, the safety of almost no cars, and scenic views that never end throughout the course.

🌊A Miraculous Course: Running with Ocean Views

While many beaches in Okinawa are wonderful for sightseeing, runners often face the challenge of having few roads that run directly along the shore.

  • 1.The stunning view of Kerama Blue from the Aka Bridge, looking down to the clear ocean floor.
  • 2.The beautiful coastline of Geruma Island. A blissful experience of running with the horizon in sight, listening to the sound of waves.

Having the unobstructed scenic view all to yourself. That is the ultimate reason to run on Aka Island.

Aka Port Start: The Ultimate 7km 3-Island Route

Starting from Aka Port, you will first head to Nishibama Beach to enjoy the spectacular ocean views. Then, cross the iconic Aka Bridge to neighboring Geruma Island, and continue over another bridge to Fukaji Island (Kerama Airport). Over 70% of the entire route runs along the open coastline, creating a dream environment for runners. The sense of achievement from running across three different islands under your own power is truly unmatched.

Runner's Voice実走インプレッション
  • The view from the iconic Aka Bridge is Kerama Blue at its absolute peak — you will stop running. You simply cannot help it. Due to the elevation, the incredible transparency allows you to see all the way down to the coral reefs below.
  • The coastal road of Geruma Island after crossing the bridge has virtually zero traffic. This blissful section, where only the sound of waves and your footsteps echo, will truly make you feel like you are running on a remote island.
  • The area around Geruma School and Kerama Airport serves as a quiet turnaround point. Since vending machines are only available near Aka Port, be sure to prepare hydration beforehand. The lack of shade will be a test during the summer.
  • The road is perfectly paved, allowing a smooth run in road shoes. The chance of encountering wild Kerama deer in the village or grass is extremely high, and the possibility of running alongside them is part of this course’s magic.

⚠️ Important Notes

STOP
!

Booking the vessel takes absolute priority over hotels.

Vessels to Kerama (especially high-speed ones) sell out incredibly fast on weekends during peak season. A common and costly mistake: booking the hotel first, only to find vessel tickets already sold out — and paying cancellation fees with nothing to show for it. The golden rule is to secure your round-trip vessel ticket before finalizing hotel bookings.
  • 💳
    Many shops and diners do not accept credit cards. Please carry sufficient cash.
  • 🦌
    Kerama deer (a natural monument) walk around the village. Please do not feed or startle them, and watch over them from a polite distance.
  • *
    There are no convenience stores. Vending machines and shop hours are limited. It is safest to buy snacks in Naha in advance.
  • *
    Street lights are sparse outside the village. A flashlight (or smartphone light) is highly recommended for night walks.

Frequently Asked Questions

Q

How do I get to Aka Island from Naha? Which is better, the high-speed vessel or the ferry?

A
You can take either the high-speed vessel “Queen Zamami” (approx. 50 mins) or the “Ferry Zamami” (approx. 90 mins) from Tomarin Port in Naha. The high-speed vessel is highly recommended if you are visiting for a day trip or want to maximize your time on the island. However, the ferry is also popular as it is less prone to rocking and offers cheaper fares. Since tickets sell out very quickly during the summer season and long weekends, booking your tickets in advance is absolutely essential.
Q

What is the best mode of transportation on Aka Island?

A
Rental bicycles (including electric-assist bicycles) or rental scooters are the best ways to explore the island efficiently. If you plan to cross over to neighboring Geruma Island, you will have to climb a steep slope over the Aka Bridge, so an electric bicycle is recommended if you want to save energy. Access to the popular Nishibama Beach is relatively flat and easy. With very little vehicle traffic, running or walking at a leisurely pace is also a wonderful way to experience Aka Island.
Q

Where can I see wild Kerama Deer? What precautions should I take?

A
Kerama deer live across Aka Island and Geruma Island. You can frequently spot them walking around the village, on Maehama Beach, and near the Aka Bridge, especially in the early mornings and evenings. As they are designated as a national natural monument, please never feed them or approach them too closely to avoid startling them.
Q

Where is the best beach or spot to swim with sea turtles?

A
Aka Beach, located within walking distance from the port, is famous for sea turtles. The shallow sea grass bed near the shore serves as their feeding ground, giving you a high chance of encountering them around high tide. However, because it is close to the harbor where boats operate, please practice safety and stay inside the designated swimming buoys.
Q

Are there diners, cafes, or shops to eat lunch on the island?

A
There are a few cafes and local diners in the village serving lunch options like Okinawa soba or taco rice. However, they may close unexpectedly or off-season, so checking their hours in advance is recommended. There are no convenience stores, and local shops close early in the evening. We recommend buying light meals and drinks in Naha before boarding.
