Nichinan Coast Guide: Aoshima, Sun Messe & the Scenic Drive

Why the Nichinan Coast Is Worth the Drive

The Nichinan coast (日南海岸) runs south from Miyazaki city along Route 220 and 222, hugging the Pacific coastline through a landscape of subtropical palms, dramatic cliffs, and turquoise water. In roughly 50 km, this stretch packs three of Miyazaki Prefecture's top attractions: Aoshima Island with its volcanic rock formations, the Easter Island Moai replicas at Sun Messe Nichinan, and Udo Jingu — a Shinto shrine built inside a cave on an ocean cliff.

What makes the Nichinan coast distinctive is the density of worthwhile stops. Unlike many Japanese scenic drives where highlights are spaced hours apart, here you can visit a subtropical island, see the world's only authorized Moai replicas, and explore a cliffside cave shrine — all within a single day. The coastal road itself is part of the experience, with pullouts offering views of the Pacific stretching to the horizon.

This guide covers what to see and do along the coast. For broader trip planning in the region, see our Miyazaki city guide.

Aoshima Island and the Devil's Washboard

Aoshima Shrine and Subtropical Garden

Aoshima (青島) is a small island connected to the mainland by the Aoshima Ohashi Bridge. According to the Aoshima Tourism Association, the island is covered in subtropical vegetation — including betel palms and phoenix palms that give it a distinctly tropical feel unusual for mainland Japan.

Aoshima Shrine sits at the center of the island, surrounded by dense jungle-like growth. The shrine grounds are free to enter and open daily, with the shrine itself open from 8:30 to 17:00. The approach through the subtropical garden feels more like Southeast Asia than Kyushu.

From JR Aoshima Station on the Nichinan Line, the island is a 15-minute walk through a small beach town. Parking is free near the bridge.

Oni no Sentakuita Rock Formations

Surrounding Aoshima at low tide, the Oni no Sentakuita (鬼の洗濯板, Devil's Washboard) are concentric rings of hexagonal rock formations extending from the island's shore. These volcanic basalt columns, shaped by millions of years of wave erosion, create a natural pattern that looks deliberately carved. The effect is most dramatic at low tide, when you can walk across the exposed rock shelves.

Check tide times before visiting — at high tide, the formations are largely submerged and far less impressive. Morning visits typically combine well with low tide viewing and good light for photography.

Sun Messe Nichinan: The Moai Statues

Sun Messe Nichinan (サンメッセ日南) is a hilltop park overlooking the Pacific that features seven Moai statues — the only replicas in the world authorized by Easter Island (Rapa Nui) elders. According to the Miyazaki Prefecture tourism site, Japanese restoration experts helped repair the original Moai on Easter Island, and these replicas were created as a gesture of gratitude.

The seven statues stand in a row facing the ocean, each said to grant a different blessing — health, love, wealth, academic success, marriage, business, and safe travel. Visitors touch specific Moai for the blessing they seek.

Set your expectations correctly: these are clean, modern replicas, not weathered ancient stones. The park is well-maintained with manicured grounds, ocean viewpoints, and a cafe. The combination of the Moai against the Pacific backdrop makes for memorable photos regardless.

• Hours: 9:00-17:30 (last entry 17:00)
• Admission: Adults ¥1,000 (~$7), children (elementary/middle school) ¥500 (~$3), preschool free
• Closed: 1st and 3rd Wednesdays each month — check the calendar before visiting
• Parking: ¥300 (~$2)

Sun Messe is approximately 15 km south of Aoshima along Route 220. By car, the drive takes about 20 minutes.

Udo Jingu: The Cave Shrine on the Cliffs

Udo Jingu (鵜戸神宮) is one of Japan's most unusually located shrines — built inside a natural cave in a cliff face overlooking the Pacific Ocean. The shrine is dedicated to Ugayafukiaezu, father of Japan's legendary first emperor, and the cave setting creates an atmosphere unlike any standard shrine visit.

Reaching the main hall requires descending 300+ steep stone steps carved into the cliff. The descent offers dramatic ocean views, but the climb back up is demanding — especially in summer heat. Wear sturdy shoes and bring water.

At the base, the tradition is to purchase undama (うん玉, luck pebbles) for ¥300 (~$2) and attempt to throw them into a small rope-encircled urn on a rock formation below. Men throw with their left hand, women with their right. Landing the pebble inside is said to bring good fortune in marriage and children.

• Hours: 6:30-19:00 (varies by season)
• Admission: Adults ¥300 (~$2), children ¥100 (~$1)
• Open daily

Udo Jingu is about 15 km south of Sun Messe along the coast road, a 20-minute drive.

Driving the Coastal Route

The Nichinan coast drive follows National Route 220 from Miyazaki city southward, transitioning to Route 222 near Nichinan city. The full drive from Aoshima to Nichinan takes about an hour without stops, but plan for a full day with three or four stops.

A practical north-to-south itinerary:

Stop	Time Needed	Distance from Previous
Aoshima Island	1-1.5 hours	Start
Sun Messe Nichinan	1-1.5 hours	20 min drive
Udo Jingu	1-1.5 hours	20 min drive
Scenic pullouts	30 min total	Along the route

The road is well-maintained and two lanes throughout. Several unmarked pullouts between the main stops offer photo opportunities of the coast. Morning light (before noon) works best for photography heading south, as the sun illuminates the ocean side of the road.

For travelers fitting this into a broader trip, see Miyazaki in a Kyushu itinerary.

Getting to the Nichinan Coast

By Rental Car

A rental car is strongly recommended for the Nichinan coast. Cars are available at Miyazaki Airport and Miyazaki Station from major rental companies. The drive from Miyazaki city to Aoshima takes about 30 minutes, and having a car lets you stop at coastal viewpoints, manage your schedule, and cover all three main attractions comfortably in one day.

Parking is free at Aoshima, ¥300 at Sun Messe, and free at Udo Jingu.

By Train and Bus

The JR Nichinan Line runs from Miyazaki Station south along the coast. Key stops:

• Aoshima Station: 30 minutes from Miyazaki, ¥510 (~$3). Walk 15 minutes to the island.
• Nichinan Station: 60 minutes from Miyazaki. Buses connect to Udo Jingu and Sun Messe from here.

Miyazaki Kotsu buses run from Miyazaki Station to the Nichinan area (approximately 1 hour, ¥1,100/~$7). Bus frequency is limited — check current schedules before relying on public transport for the full coast.

Public transport works well for visiting Aoshima alone but is impractical for covering all three main stops in a single day. For detailed transport logistics, see our Nichinan day trip from Miyazaki guide.
