Ferry or Jetfoil for Your Trip to Sado? A Quick Overview of the Key Differences
When traveling to Sado, the first thing many people wonder is whether to take the ferry or the jetfoil. Even though both vessels operate on the same route, the travel style and overall convenience differ quite a bit, so the best choice depends on your travel purpose and what you want to prioritize.
Here, you’ll find a simple, easy‑to‑understand comparison of both options—especially helpful for anyone visiting Sado for the first time.
Who the Ferry Is Best For
The ferry is ideal for travelers who want a relaxed journey or are carrying a lot of luggage. With its spacious interior and multiple seating options, you can walk around to refresh yourself, enjoy the views from the observation lounge or outdoor deck, and experience the unique charm of traveling by sea. Because you’re free to move around, even a longer trip feels less stressful.
It’s also more affordable than the jetfoil, and you can bring cars or bicycles onboard, making it a great choice for those who want to keep costs down or bring their own transportation for exploring Sado Island.
If you value comfort, flexibility, and the ability to wander around and enjoy the atmosphere of the ship, the ferry is the better option.
Who the Jetfoil Is Best For
The jetfoil is ideal for travelers who want to reach Sado as quickly as possible. It connects Niigata and Ryotsu in about one hour, making it a major advantage for anyone who wants to minimize travel time—especially for day trips, short getaways, or travelers who want to spend as much time on the island as possible.
Although the cabin isn’t as spacious as the ferry, all seats are reserved, and the simplicity of just sitting until you arrive is part of its appeal. There’s no need to move around or deal with extra steps, making it perfect for those who prefer efficient, no‑frills transportation.
If you want to maximize your time on Sado or prioritize your experience on the island rather than the journey itself, the jetfoil is the better choice.
What Is Sado Kisen? Essential Travel Info for Getting Between Niigata and Sado Island
Travel to Sado Island is primarily done by using the vessels operated by Sado Kisen. As the main public transportation link between Niigata and Sado Island, Sado Kisen plays an essential role for both tourists and local residents. In this section, we’ll take a closer look at Sado Kisen’s operating routes and explain the key differences between the Ferry and the Jetfoil.
Operating Routes
Sado Kisen’s main operating route connects Niigata Port with Ryotsu Port. Departing from Niigata Port—conveniently located near the city center—this route takes you to Ryotsu Port, the primary gateway to Sado Island. It is the most commonly used connection for both sightseeing and everyday travel.
Several rental car companies are located around Ryotsu Port, allowing you to pick up a car immediately after disembarking and begin exploring the island. Because Sado Island is quite large, renting a car is one of the most efficient ways to get around, making Ryotsu an ideal starting point even for first-time visitors.
Whether you choose the Ferry or the Jetfoil, this Niigata–Ryotsu route serves as the standard option. With frequent departures and a wide range of time slots, it’s easy to plan your trip around this highly convenient connection.
Features of the Large Ferry (Car Ferry)
The large ferry offers spacious interiors, allowing passengers to move around freely throughout the vessel.
Seats on the ferry are divided into different classes, ranging from standard seating to more spacious premium options. There are also carpeted areas where passengers can lie down and relax, allowing you to choose the style of comfort that best suits your preferences.
Observation rooms and open decks are available on the ferry, allowing passengers to enjoy views of the sea during the voyage or step outside for fresh air and a quick change of mood—perfect for experiencing the charm of traveling by ship. There are also vending machines selling bento meals on board, making it easy to grab a light snack while you’re on the move.
Because the ferry operates as a car ferry, you can bring your own vehicle, motorcycle, or bicycle on board, making it convenient if you want to use your own transportation on Sado Island. It’s an ideal option for trips with a lot of luggage or for travelers who plan to explore the island widely.
Features of the Jetfoil (High‑Speed Vessel)
The jetfoil is a high‑speed vessel that lifts above the water surface as it travels, allowing passengers to reach Sado in a much shorter time. Connecting Niigata and Ryotsu in about one hour, it’s an excellent choice for travelers who want to minimize their travel time.
All seats on the jetfoil are reserved, and the cabin layout is similar to that of an airplane. Passengers are required to wear seatbelts during the voyage, and moving around the cabin is not permitted. As a result, the interior is kept simple and efficient, allowing travelers to sit down and simply ride straight to their destination.
The jetfoil offers only essential facilities, with a design focused entirely on short‑distance, high‑speed travel.
Do Ferries and Jetfoils Shake? What I Learned from Actually Riding Them
One of the things travelers often wonder about when taking a boat to Sado is how much the ferry or jetfoil will shake. Because ferries and jetfoils differ in structure and the way they travel, it’s generally said that the motion you feel on board can vary between the two. In this section, I’ll explain how each vessel moves based on what I actually experienced during the trip.
How Ferries and Jetfoils Move in Rough Conditions
Ferries have large, heavy hulls, which makes them absorb small waves more easily. Because they travel at a moderate speed and remain firmly in contact with the water surface, you generally won’t feel much motion under normal sea conditions.
Jetfoils, on the other hand, are high‑speed vessels but are also designed to minimize shaking in typical conditions. Their hydrofoil system lifts the hull above the water while underway, reducing the area affected by waves and helping maintain a stable posture. However, on days with high waves or strong winds, the foils may not rise fully, and some motion can be felt.
Based on my own experience, both the ferry and the jetfoil had almost no noticeable shaking. The sea was calm that day, but even so, both vessels were far more stable than I expected and provided a comfortable ride.
Which Is Better for People Prone to Motion Sickness?
As mentioned in the previous section, both the ferry and the jetfoil were far more stable than I expected, and I barely felt any significant motion. Still, for travelers who worry about seasickness or are naturally prone to motion sickness, choosing the more comfortable option can be an important consideration.
Ferries are generally considered less likely to cause seasickness because their large, heavy hulls absorb wave motion more effectively. Being able to walk around the cabin also helps you refresh yourself if you start feeling uncomfortable. However, because ferries move slowly, they can sometimes produce a gentle, swaying motion that follows the rhythm of the waves, and some people may find this type of movement difficult.
Jetfoils, meanwhile, are designed to minimize shaking under normal conditions thanks to their high‑speed travel and hydrofoil system, which lifts the hull above the water. The downside is that passengers must remain seated with seatbelts fastened throughout the journey, so you can’t stand up or change posture if you begin to feel unwell. On days with rough weather, the jetfoil may also experience more noticeable motion, which can be challenging for those who are sensitive to seasickness.
Considering these characteristics, I felt that the ferry (the larger vessel) is generally the more reassuring option for people who are prone to motion sickness. Being able to move around freely and distract yourself, along with the relatively gentle type of motion, makes it easier to manage your condition during the trip.
Difference in Travel Time
Travel time to Sado differs significantly between the ferry and the jetfoil, and which one you choose depends on your travel style and what you want to prioritize.
■ Ferry (Car Ferry)
Travel time: approximately 2 hours and 30 minutes.
The ferry is ideal for travelers who want to enjoy a relaxed journey. Because you can freely walk around inside the ship, it’s easy to take in the views, lie down to rest, or simply spend the time at your own pace, making it a good choice for those who prefer a slower, more leisurely trip.
■ Jetfoil
Travel time: approximately 1 hour.
The jetfoil reaches Sado in less than half the time of the ferry, making it ideal for travelers who want to minimize travel time or move efficiently on a day trip.
Can You Bring a Dog on Board?
Sado Kisen allows passengers to bring dogs on board. When I traveled by ferry, I saw several people with their dogs, and all of them seemed relaxed and comfortable during the trip. However, the rules for pets differ between the ferry and the jetfoil, and the available facilities vary depending on the vessel type, so it’s best to check the official Sado Kisen website for the most accurate details. The information below is summarized based on what is listed on the official site.
■ Ferry (Car Ferry)
Ferries offer two options for traveling with pets: a Pet Corner where you can stay together with your dog, and a Pet Cage Area where pets are kept in their own carriers. The Pet Corner is an open, shared space on part of the deck where owners and pets can spend time in the same area. No reservation is required, and passengers simply share the space with others. The Pet Cage Area, on the other hand, is a dedicated room equipped with heating and air‑conditioning, where pets are kept inside their carriers. This room is locked during the voyage, so owners cannot enter while the ship is underway. Reservations are not required for this option either.
■ Jetfoil
Jetfoils follow different rules from ferries, and only small pets are allowed inside the cabin. Pets must be kept in a transport container, such as a pet carrier, which must be placed at your feet during the trip. The carrier must be one in which the pet’s entire body fits and the head cannot come out, and owners are required to ensure that their pets do not stick their face or body out while inside the cabin.
Because the ferry offers spaces where you can stay together with your pet, it felt like the more convenient option for traveling with a dog. Jetfoils are certainly faster, but since pets must remain fully secured inside their carriers, whether it’s suitable or not will likely depend on your dog’s temperament.
Can You Walk to the Ferry Terminal? How to Get from Niigata Station
The Sado Kisen ferry terminal is located a short distance away from Niigata Station. Under normal circumstances, the easiest option is to take the “Sado Kisen” bus from the station’s main bus terminal, which gets you there in about ten minutes. However, if you’re catching an early‑morning ferry, there may be times when the buses are not yet running.
In those situations, walking can surprisingly be a practical option. The distance from Niigata Station to the ferry terminal is about 2 km, and while Google Maps estimates the walk at around 30 minutes, it doesn’t feel that long in practice. When I walked there for an early‑morning departure, it took me just under 25 minutes. The route is easy to follow, and the fresh morning air makes the walk feel more like a pleasant stroll. Since there were few cars at that hour, I enjoyed a quiet and peaceful walk through the city.
There are also rental bicycle ports both in front of Niigata Station and at the ferry terminal. If you don’t have enough time to walk but don’t feel the need to take a taxi, renting a bicycle is a convenient alternative. As long as you’re traveling light, you can simply rent a bike at the station and return it at the terminal, which makes it very easy to use. (Here is the official website for the rental bicycles.)
Of course, when you have a lot of luggage or the weather is bad, taking the bus is definitely the easier option. But for early‑morning departures or when you have some extra time, walking or using a rental bicycle can work perfectly well. Once you actually try walking the route, you’ll likely find that it feels much less demanding than the distance suggests.
That’s everything covered in this article. Whether it’s the ferry, the jetfoil, or the access from Niigata Station, you’ll likely find that many parts of the journey feel more comfortable than you might expect once you actually experience them. Try to enjoy even the small moments of getting around before heading to Sado—they’re all part of the trip. By the time you step aboard, you’ll probably already feel that your journey has begun.
