Okayama to Naoshima: Ferry Access, Routes & Day Trip Planning

Okayama to Naoshima: The Route Overview

Naoshima (直島) — the art island in the Seto Inland Sea — is most commonly reached from the Okayama side, even though it technically belongs to Kagawa Prefecture. The route is straightforward: JR Okayama Station to Uno Station by train, a short walk to Uno Port, then a ferry across to the island. Door to door, you are looking at roughly 1 hour and 15 minutes.

This guide covers the transport logistics: train options, ferry routes, port choices, and on-island transport. For broader Okayama planning, see our Okayama city guides and Okayama travel overview.

Segment	Transport	Time	Cost
Okayama Station → Uno Station	JR Uno Line	~50 minutes	~¥800 (~$5)
Uno Station → Uno Port	Walk	~5 minutes	Free
Uno Port → Miyanoura Port	Regular ferry	~20 minutes	¥300 (~$2)
Total	—	~1 hour 15 minutes	~¥1,100 (~$7)

JR Uno Line from Okayama Station to Uno Station

The JR Uno Line (JR宇野線) runs from Okayama Station south to Uno Station on the coast. The ride takes approximately 50 minutes and costs around ¥800 (~$5) one way. Trains run roughly 1-2 times per hour — this is a local line, not a high-frequency urban service, so check the schedule before heading to the platform.

The JR Pass covers the Uno Line, so if you are traveling on a Japan Rail Pass, this leg is included. The ferry, however, is a separate operator and costs extra.

Uno Station is a small terminal station. When you exit, follow signs toward Uno Port (宇野港) — the walk takes about 5 minutes. The route is flat and well-signed, passing through a quiet portside area with some public art installations that hint at the art island waiting across the water.

Uno Port to Naoshima: Ferry Options

Shikoku Kisen (四国汽船) operates the ferries between Uno Port and Naoshima. There are two main services: a regular ferry to Miyanoura Port and a high-speed boat to Honmura Port.

Regular Ferry to Miyanoura (20 Minutes)

The regular ferry from Uno Port to Miyanoura Port (宮ノ浦港) is the standard route most visitors take. The crossing takes approximately 20 minutes, and tickets cost ¥300 (~$2) one way for adults. No reservation is needed — buy your ticket at the port kiosk and board.

According to the Shikoku Kisen timetable, ferries run approximately 12 times daily between 6:10 and 20:25. The last ferry departing Miyanoura back to Uno is around 20:25 — miss it and you are staying overnight on the island.

The ferry also carries vehicles. Car fares range from ¥1,500 to ¥2,600 (~$10-17) for vehicles under 6 meters, plus the driver's passenger fare. Bringing a bicycle costs ¥310 (~$2) in addition to your passenger ticket.

High-Speed Boat to Honmura

A high-speed boat service connects Uno Port to Honmura Port (本村港) on the northern side of Naoshima. The crossing is slightly faster at approximately 15 minutes, and fares are estimated at ¥520 (~$3) one way.

The high-speed boat has reduced winter service: from December through February, it operates only on Mondays, Fridays, Saturdays, Sundays, and public holidays. Summer months see additional departures. Check the Shikoku Kisen website for the current schedule.

Choosing between the two services depends on which part of Naoshima you want to reach first — more on that below.

Miyanoura vs Honmura: Which Port to Choose

Naoshima has two ports, and which one you arrive at affects your first hour on the island.

Miyanoura Port (宮ノ浦港) is the main arrival point on the southern end of the island. This is where you arrive if you take the regular ferry — and where most visitors start. The Benesse Art Site, Chichu Art Museum, Lee Ufan Museum, and Benesse House are all accessible from here. The iconic red pumpkin sculpture by Yayoi Kusama sits right at the port.

Honmura Port (本村港) is on the northern side, closer to the Art House Project — a series of installations in converted houses and workshops throughout the old village. If the Art House Project is your priority, arriving at Honmura saves you a bus ride.

The two ports are about 15 minutes apart by bus. Since most visitors want to see both areas, the choice is really about which end to start from. The regular ferry to Miyanoura runs more frequently and is cheaper, making it the default for most itineraries.

Getting Around Naoshima Without a Car

Naoshima is small — roughly 8 km (5 miles) from end to end — but hilly enough that walking between all the sites would be tiring. Two practical options cover the island well.

Town Bus Between Ports

The Naoshima town bus runs between Miyanoura Port and Honmura, stopping at major art sites along the way. Buses run every 15-20 minutes during peak hours. The ride between ports takes about 15 minutes. Fares are low — check at the port information counter for the current rate.

Bus timing can be tight if you are trying to visit multiple museums with timed entry. Build in buffer time rather than depending on catching a specific departure.

Bicycle Rental at the Port

Renting a bicycle at Miyanoura Port is the most flexible way to explore the island. Rental shops near the port charge approximately ¥500 (~$3) per day for a standard bicycle. Electric-assist bikes are also available for the hills — worth considering given the island's terrain.

Cycling lets you move between sites on your own schedule without waiting for buses. The roads are quiet, the distances are short, and the coastal scenery between stops is part of the experience. If you are visiting in summer, bring water and sunscreen — shade is limited on some stretches.

Day Trip Timing: Sample Schedules

A day trip from Okayama to Naoshima is entirely feasible and is how most visitors experience the island. The key constraint is ferry timing — you want to arrive early enough to see the main sites and leave comfortably before the last ferry.

Recommended Day Trip Schedule

Time	Activity
7:00	Depart Okayama Station on JR Uno Line
7:50	Arrive Uno Station, walk to Uno Port
8:12	Board ferry to Miyanoura
8:32	Arrive Miyanoura Port, rent bicycle or board bus
9:00-12:00	Chichu Art Museum, Lee Ufan Museum, Benesse House area
12:00-13:00	Lunch on island
13:00-16:00	Art House Project (Honmura area)
16:30-17:00	Return to Miyanoura Port
17:00+	Ferry back to Uno
18:00	Back in Okayama

This gives you 6-7 hours on the island — enough for the major sites at a moderate pace. Arriving on the first available ferry is strongly recommended. Many visitors on Reddit report wishing they had started earlier.

If you want a more relaxed pace, staying overnight on Naoshima or at a hotel near Uno Port eliminates the time pressure. For broader Okayama prefecture highlights, a multi-day base in Okayama city works well.

Things to Know About Timing

• Last ferry from Miyanoura to Uno departs around 20:25. Missing it means an unplanned overnight stay.
• Museum entry times matter. Chichu Art Museum uses timed tickets — book online in advance, especially during Setouchi Triennale years.
• Winter schedules are reduced. Both ferry and high-speed boat have fewer departures from December through February.
• Mondays are tricky. Some Naoshima museums close on Mondays. Check opening days before planning a Monday visit.
