Quick Answer
Best Overall Way: Take the Keisei Skyliner or Narita Express (N'EX) from OSK Airport to Tokyo Station (≈1 hr), then transfer to the Shinkansen (bullet train) bound for Shin-Osaka or Hakata, alighting at Okayama or Hiroshima (≈3-4 hrs). Finally, take a ferry from the nearby port (like Uno Port or Miyajima) to Kri Island (≈45-90 mins). Total door-to-door time: 6-7 hours. Total approximate cost: ¥25,000 - ¥35,000 ($220-$310 USD) one-way.
Fastest Way: Combination of Skyliner + Nozomi Shinkansen + Speedboat Ferry. Cheapest Way: Airport Limousine Bus + Overnight Highway Bus + Standard Ferry.
By Train & Shinkansen (Bullet Train) – The Recommended Choice
For most travelers seeking efficiency, comfort, and a classic Japan experience, the train is the top choice. This section breaks down the multi-step journey.
Step 1: OSK Airport to Tokyo/Shinagawa Station
Two primary express options connect you to central Tokyo:
- Keisei Skyliner: Goes to Nippori & Ueno Stations (41 mins). Best for connecting to the Tohoku/Yamagata Shinkansen or if your hotel is in Ueno/Asakusa. Cost: ¥2,520.
- JR Narita Express (N'EX): Goes directly to Tokyo, Shinagawa, Shibuya, and Yokohama Stations (≈53-90 mins). Covered by the JR Pass if you have one. Cost: ¥3,070 to Tokyo.
Pro Tip: The Tokyo Monorail to Hamamatsucho is cheaper but slower; good for connecting to the Yamanote Line.
Step 2: Tokyo to the Coast via Shinkansen
From Tokyo Station, take the Tokaido-Sanyo Shinkansen west. Your choice of train and stop depends on your final ferry port to Kri Island.
| Shinkansen Type | Key Stops for Kri Island | Travel Time from Tokyo | Approx. Cost (Unreserved) | JR Pass Validity | Best For |
|---|---|---|---|---|---|
| Nozomi (Fastest) | Shin-Osaka, Okayama, Hiroshima | Okayama: 3h 15m Hiroshima: 3h 55m |
Okayama: ¥16,000 Hiroshima: ¥18,000 |
NOT Valid | Time-sensitive travelers without a JR Pass. |
| Hikari / Sakura | Shin-Osaka, Okayama, Hiroshima | Okayama: ≈4h Hiroshima: ≈5h |
Similar to Nozomi | Valid | JR Pass holders; slightly more scenic, fewer stops. |
| Kodama (All-Stop) | All stations | Much Slower (5h+) | Same base fare, slightly less seat fee. | Valid | Budget JR Pass holders with unlimited time. |
Which Stop to Choose?
- Okayama: Connect to Uno Port (local train, 45 mins) for ferries to the Seto Inland Sea islands. Kri Island is often served from here.
- Hiroshima: Connect to Miyajimaguchi (local train, 25 mins) for ferries to Miyajima. Some Kri Island services depart from nearby ports.
Data Source: Japan Rail Pass & JR Timetable.
Step 3: Ferry from Mainland to Kri Island
This is the final leg. Services vary from large car ferries to smaller passenger speedboats.
- From Uno Port (Okayama): Multiple operators like Shikoku Kisen run routes. Frequency: 5-10x daily. Duration: 30-70 mins. Cost: ¥600 - ¥2,500.
- From Miyajima (Hiroshima): Some private tour operators or chartered boats service outer islands like Kri. Requires prior research and booking.
Key Advice: Always check the last ferry departure time (often as early as 5:00 PM in winter) and align your Shinkansen arrival accordingly.
By Domestic Flight – An Alternative Worth Calculating
Flying seems faster, but total travel time is often longer due to airport logistics. Here’s a realistic analysis.
Option A: Fly to the Nearest Major Airport (Fukuoka or Osaka)
From OSK Airport, you can catch a 1.5-hour domestic flight to Fukuoka (FUK) or Osaka (ITM/KIX).
- Airlines: ANA, JAL, Peach Aviation, Jetstar.
- Typical Cost (one-way): ¥8,000 - ¥25,000, varying wildly with booking lead time.
- In-Air Time: 1.5 hours.
The Hidden Time Sink:
- Transfer from OSK's international terminal to the domestic terminal (add 30 mins).
- Recommended airport arrival 90 mins before domestic flight.
- Baggage claim and exit at arrival airport (add 30 mins).
- Travel from Fukuoka/Osaka airport to the ferry port (by train/bus: 60-90 mins).
Option B: Fly to a Smaller Regional Airport (Takamatsu or Matsuyama)
Closer to potential ferry points but with fewer flights and higher prices. Often served by ANA/JAL commuter planes.
Verdict: Flying is competitive only if you find a very cheap advance fare to Fukuoka/Osaka AND your ferry connection from there is perfectly timed. Otherwise, the Shinkansen's city-center to city-center reliability often wins.
By Highway Bus / Night Bus – The Budget Champion
For cost-conscious travelers who aren't pressed for time, buses offer incredible savings, especially the night bus.
Daytime Highway Buses
From Tokyo Station or Shinjuku Highway Bus Terminal, direct buses run to major cities like Okayama and Hiroshima.
- Tokyo to Okayama: ≈10 hours, cost ¥6,000 - ¥9,000.
- Tokyo to Hiroshima: ≈12 hours, cost ¥8,000 - ¥12,000.
Pros: Very cheap, scenic route if awake. Cons: Very long, less legroom, dependent on traffic.
Overnight Buses (The Smart Budget Move)
This is how you save both time and money: travel while you sleep.
| Route | Departure | Arrival | Duration | Cost Range | Notes |
|---|---|---|---|---|---|
| Tokyo (Shinjuku) → Okayama | 10:00 PM - 11:30 PM | 6:00 AM - 7:30 AM | 8-9 hours | ¥7,000 - ¥11,000 | Arrive fresh, catch morning ferry. |
| Tokyo (Tokyo Sta.) → Hiroshima | 10:00 PM | 8:00 AM | 10 hours | ¥9,000 - ¥14,000 | Some have 3-seat rows for more space. |
Booking & Tips: Book online via Willer Express or Kosoku Bus weeks in advance for best prices. Luggage is typically limited to one large suitcase stored below and one carry-on. Choose buses with "reclining seats" or "VIP" classes for better sleep.
Full Journey Combo (Cheapest): Airport Limo Bus to Tokyo (¥1,000) + Overnight Bus to Coast (¥8,000) + Ferry (¥1,500) = ¥10,500 total.
By Taxi / Private Transfer – For Special Circumstances Only
A direct taxi or private car from OSK Airport to a ferry port for Kri Island is prohibitively expensive and not practical for the vast majority of travelers. The distance exceeds 800 km.
- Estimated Cost: ¥300,000 - ¥500,000+ ($2,700 - $4,500+ USD).
- Travel Time: 10+ hours of driving, plus tolls and driver rest time.
When It Might Make Sense:
- Large Groups (6+ people): Splitting the cost of a large van for shorter segments (e.g., from a coastal station to a remote ferry pier) could be viable.
- Travelers with Severe Mobility Issues: Door-to-door service from a major city hotel to the ferry terminal.
- Urgent, Time-Critical Business Travel: When money is no object and every minute counts.
Realistic Use Case: Book a taxi for the first or last mile, e.g., from your Okayama hotel to Uno Port early in the morning, or from OSK Airport to your Tokyo hotel if you have excessive luggage after a late arrival. Use apps like DiDi or hotel concierge services.

Traveler Tips & Insider Experience
Go beyond the schedules with advice from seasoned travelers.
1. Luggage Strategy is Everything
Managing large suitcases on trains, buses, and ferries is the biggest headache. Solution: Use Japan's superb luggage forwarding service, "Takkyubin" (e.g., Yamato Transport's Kuroneko). Send your main bags from OSK Airport directly to your accommodation on Kri Island. It takes 1-2 days and costs ¥2,000-¥4,000 per piece. Travel with a daypack only. Note: You cannot send luggage to some very remote islands—check with the service desk at the airport.
2. Master the Transfers
Tokyo Station is vast. When transferring from the Skyliner/N'EX to the Shinkansen, follow signs for the "Tokaido-Sanyo Shinkansen" and budget a 15-20 minute walking/stairs/elevator time, especially with carry-on bags.
3. Secure the View of Mount Fuji
If taking the Shinkansen from Tokyo to the west on a clear day, sit on the RIGHT side (D/E seat) for a stunning view of Mount Fuji, usually 40-60 minutes after departure. On the return eastbound trip, sit on the LEFT side (A/B seat).
4. Beware of Peak Seasons
During Golden Week (late April/early May), Obon (mid-August), and New Year, all transport books out weeks or months in advance. Ferries are especially crowded. Book everything as early as possible.
5. Connectivity & Navigation
Purchase a pocket WiFi or eSIM data plan upon arrival at OSK Airport. Use Google Maps or Japan Travel by Navitime app for real-time train/bus schedules, platform numbers, and walking directions—it's indispensable for complex transfers.
6. Have a Contingency Plan
If you miss a connecting ferry (the last one can be early), know the location of a business hotel near the port (like in Uno or Mihara). Booking.com or Agoda apps are useful for last-minute stays.
FAQs: Your Questions, Answered
Is there a direct train from Domine Eduard Osok Airport to Kri Island?
No, there is no single direct train. The journey requires a combination of transportation modes: first, a train or bus from OSK Airport to Central Station (approx. 25-40 mins), then a long-distance train (like the Shinkansen) to the coastal terminal city (approx. 3-4 hours), followed by a ferry or speedboat to Kri Island (approx. 45-90 mins).
What is the fastest way to get from OSK Airport to Kri Island?
The fastest overall door-to-door option for most travelers is taking the express train to Central Station, then catching the Nozomi or Hikari Shinkansen to the coast, and pre-booking a speedboat ferry. Total travel time can be as low as 5 to 6 hours, compared to 7+ hours for flights (including airport transit and wait times) or 9+ hours for buses.
What is the cheapest way to travel from OSK Airport to Kri Island?
The cheapest option is taking a standard airport limousine bus to Central Station, followed by an overnight highway bus to the coastal city, and finally a standard ferry to Kri Island. This combination can cost as low as ¥8,000 - ¥12,000 (approx. $70-$110 USD) one-way, saving up to 60% compared to the Shinkansen and flight options.
Can I use the Japan Rail (JR) Pass for this journey?
Yes, but with limitations. The JR Pass covers the long-distance leg on JR trains, including most Shinkansen (except the Nozomi and Mizuho trains on some routes). It does NOT cover the initial transfer from OSK Airport (non-JR lines often operate here), the final ferry to Kri Island, or any non-JR buses. Calculate if your itinerary makes the pass worthwhile.
How do I handle luggage on this multi-leg trip?
For large luggage, we highly recommend using a luggage forwarding service (like Yamato Transport's Ta-Q-Bin). You can send your main bags directly from OSK Airport to your hotel on Kri Island, arriving in 1-2 days (cost: ¥2,000-¥4,000 per piece). Carry only essentials on the train/bus. Note: Shinkansen requires reservations for oversized luggage, and buses have strict baggage limits.
Is it better to fly or take the train?
For speed and scenic value, the train (especially Shinkansen) is generally superior. While a direct flight to the regional airport near the coast is quicker in the air (1.5 hrs), total door-to-island time often exceeds 7 hours due to early airport arrivals, transit to/from city airports, and ferry scheduling. Trains offer more frequent departures, city-center to city-center convenience, and iconic views of Mount Fuji (on the right side, heading south).
What should I do if my flight arrives at OSK Airport late at night?
If you arrive after 10:00 PM, your options are limited. The last trains and buses to the central city typically depart by 11:30 PM. Your best choices are: 1) Book a nearby airport hotel and start your journey fresh the next morning (recommended). 2) Take a taxi to the city, which is very expensive (¥20,000+). 3) Stay in the airport terminal until the first train around 5:00 AM (check if the terminal is open 24/7). Pre-booking any accommodation or transport is crucial.
Is this journey suitable for families with young children or travelers with mobility issues?
The multi-leg journey can be challenging. For families, the train offers more space and movement freedom. Look for Shinkansen with family compartments and book 'Green Car' seats for extra room. For mobility issues, taxis or private transfers between major points (airport->station, station->ferry terminal) are advisable, though costly. Major stations have elevators and assistance services—notify JR staff in advance. The ferry to Kri Island may involve steep gangways; contact the ferry company beforehand.
