Overview (history, characteristics, attractions)
The Kaichu Road is a driveway that crosses the sea in Uruma City, in the central part of Okinawa's main island, and its greatest attractions are the straight road that stretches over the sea and the emerald green sea that spreads out on both sides. Originally an artificial road and embankment built to improve transportation convenience connecting the main island with remote islands, it was completed after the Showa period and is now both a local community road and a tourist attraction.
Its distinctive feature is the exhilarating feeling of "driving through the ocean." On sunny days, the typical blue ocean and sky of Okinawa stretch out in a straight line, making it a popular spot for driving, cycling, and photography. Along the road, there are parking spaces and observation points, as well as bridges and access roads to the surrounding islands, and it also serves as a base for access to nearby beaches and tourist facilities.
Highlights
-
Driving along the Mid-Sea Road / Scenery
The contrast between the straight road and the sea on both sides is striking. The color of the sea changes depending on the angle of the light in the morning and evening, making it a particularly popular photo spot at sunset. -
Observation point and rest area
There are parking spaces and small observation areas along the way and on both sides where you can take photos and take a stroll. You can enjoy the ocean view while feeling the sea breeze. -
Nearby beaches and sea activities
The islands that can be reached via the Mid-Sea Road are dotted with beaches, spots for playing on the rocks, and snorkeling spots (the water is often very clear on some days). -
Roadside stations and facilities (e.g., Ayahashi-related facilities)
There are restaurants and establishments in the surrounding area that sell local seafood and souvenirs, so you can enjoy local cuisine (the names of the facilities and their opening hours may change depending on the season, so it is recommended that you check in advance).
Access (nearest station, transportation, etc.)
-
Railway
The Okinawa main island's railway (Yui Rail) only goes as far as Naha city, so there is no station nearest to the Mid-Sea Road. If you are using the train, you will need to transfer from Naha (Yui Rail) to a bus or rental car. -
Car (rental car)
The most convenient way to get there is by rental car. From Naha Airport, it takes about 50 minutes to an hour using regular roads and expressways (depending on traffic conditions). Parking spaces are limited at certain spots, so if the parking lot is full, please drive around the area and find another parking spot. -
Local bus
There are bus routes available from Naha and southern and central Okinawa, but the number of buses is limited, so it's important to check the timetable in advance. Some areas can be reached on foot from the nearest bus stop, while others require walking or cycling. -
Walking and cycling
Many tourists enjoy cycling along the Mid-Sea Road from nearby accommodations. However, there are some sections where there are no sidewalks or bicycle paths, so please be careful when riding on the road.
Estimated stay (estimated time required)
- Just drive through and enjoy the scenery: about 30 minutes (drive only)
- Including photography and strolling around the observation deck: 1-2 hours
- Day trips to nearby beaches and islands: Half a day to a full day (visiting island beaches and tourist attractions)
Nearby spots

- Hamahiga Island (sacred places such as Shirumichu) — This island is known for its Ryukyuan folklore and sacred spots.
- Katsuren Castle Ruins (Uruma City) — Part of the World Heritage Site "Gusuku Sites and Related Properties of the Kingdom of Ryukyu" and recommended for historical walks.

Things to be aware of (crowds, manners, seasonal precautions, etc.)
-
congestion
On weekends, holidays, and in the summer, the drive and observation points can get crowded, and the parking lot can fill up. In particular, the number of visitors coming to take photos increases during sunset in the evening. -
safety
There are some sections where sidewalks and bicycle paths are not maintained. Please be careful when walking or cycling on the road, and we recommend wearing a helmet and reflective materials. Also, cars will be exposed to salt from the sea breeze, so please be careful of salt damage to the body of your car after parking for a long time. -
Sea etiquette
Taking shells or coral from the beach or rocky shore is prohibited and is considered bad manners. When playing in the sea, please be mindful of environmental protection and safety (tides, jellyfish, slippery surfaces). -
Weather and Season
During typhoon season (summer to autumn), high waves can cause road restrictions. Strong winds can also reduce visibility due to sea spray, so be sure to check the weather forecast beforehand. Even in winter, the sea breeze can be cold, so it's a good idea to bring a jacket. -
Check toilets, restaurants, etc.
The facilities on the Mid-Sea Road itself are limited, so if you plan to stay for a long time or explore the island, it's a good idea to check the opening hours of nearby restrooms and restaurants in advance.
The Mid-Sea Road is a picturesque spot that is perfect for just driving along. You can enjoy it even more if you combine a drive in a rental car with visiting the surrounding islands and historical sites. We recommend checking the weather and parking situation before visiting.
