When you hear the name “Sunflower,” many of you may picture a familiar sun emblem. However, did you know that these ferries are more than just a means of transportation? In fact, MOL Sunflower not only enriches your travel experience, but also helps support Japan’s economy and our everyday lives from across the seas.
In this article, we invite you to explore the lesser-known appeal and maritime “secrets” behind MOL Sunflower—its dual role in travel and logistics, as well as its initiatives for a more sustainable future.

 What Kind of Company Is MOL Sunflower?

Let us begin with a brief introduction.
MOL Sunflower Ltd. is a member of the Mitsui O.S.K. Lines (MOL) Group, a comprehensive global shipping company operating across oceans worldwide. Within the group, MOL Sunflower specializes in domestic ferry and RORO vessel operations in Japan. 
A comprehensive shipping company can be likened to a “department store of the sea,” operating a wide range of vessel types to transport people and diverse cargoes worldwide. These include container ships carrying everyday consumer goods, tankers transporting crude oil used to produce gasoline, and LNG carriers delivering natural gas for winter heating, among many other vessel types. Within this broad portfolio, the “Sunflower” focuses on Japan’s domestic sea routes and fulfills two essential roles: travel and logistics. Since its establishment, the company has placed safety first and strives to be a presence that supports both journeys and daily life.

Where Can You Travel with the Sunflower?

Many people may be interested in using the Sunflower ferries but wonder where they can board and where they go.
MOL Sunflower operates Japan’s largest domestic route network, connecting Hokkaido to Kyushu. The company offers four ferry routes and two RORO routes, allowing customers to choose the most suitable option for their destination.

Ferry Services

Ten “Sunflower” ferries operate on the following four routes:

    ・Oarai – Tomakomai (Hokkaido)

    ・Osaka – Beppu

    ・Kobe – Oita

    ・Osaka – Shibushi (Kagoshima)

Under the concept of “Casual Cruise,” these ferries offer an accessible yet high-quality onboard experience, providing a comfortable journey where passengers can feel a sense of, reassurance and trust, and maintain a connection with family, friends, and colleagues. 

RORO Vessel Services

Four RORO vessels operate on two routes:

•   ・Tokyo – Hakata

•   ・Tokyo – Kanda (Kitakyushu)

Guided by the principles of safety, speed, and reliability, these services respond to diverse customer needs by offering unmanned trailer transport between ports as well as the sea transport of manned trucks.

The Sunflower route map is available here.

By choosing the optimal route to match your current location and destination, a special journey begins—one where the journey itself becomes part of the enjoyment.

A “Moving Hotel” on the Sea: The Passenger Ferry Experience

Sunflower passenger ferries are more than just a means of transportation.
They are, in a sense, a “moving, floating hotel.”
What sets them apart is the ability to travel together with your car, while enjoying a relaxed and comfortable onboard experience.
After a good night’s sleep in a private cabin, you arrive at your destination by morning.
It is a smart travel style that truly allows you to “travel while you sleep.”

  ・The Sunflower Murasaki: In service on the Osaka–Beppu route since April 2023
  ・The Sunflower Kamuy: In service on the Oarai–Tomakomai route since January 2025
  ・The Sunflower Pirka: In service on the Oarai–Tomakomai route since July 2025

This wave of innovation has also extended to the route connecting the Kanto region and Hokkaido. In January 2025, the newly built vessel Sunflower Kamuy entered service on the Oarai–Tomakomai route. Departing from the traditional white hull, the vessel features a new blue design symbolizing the “sea at dawn.”

MOL Sunflower contributes to enhancing customer well-being by offering pleasant moments through its “Casual Cruise” concept, which allows everyone to enjoy a high-quality sea journey with ease.

Supporting Japan’s Logistics: Behind the Scenes of Cargo Transportation

The vessels that support Sunflower’s logistics operations include not only passenger ferries, but also RORO (Roll-On / Roll-Off) vessels.
Both types share the same RORO system, which allows vehicles to drive on and off the ship under their own power. However, passenger ferries are equipped with comfortable cabins and restaurants, transporting both passengers and cargo as a “moving hotel,” while RORO vessels have no passenger accommodations and specialize exclusively in cargo transportation. 

MOL Sunflower operates a total of four RORO vessels. In addition to the existing Tokyo–Kanda (Fukuoka) route, port calls at Miyazaki Port began in February 2026. This has strengthened the RORO transportation network covering all of Kyushu, including southern Kyushu, with the aim of improving logistics services.
For Miyazaki Port, this marks the first new regular shipping route in 21 years, enhancing direct maritime transportation services to the Kanto region.

Both cargo-specialized RORO vessels and passenger ferries play leading roles in supporting Japan’s logistics.
Because trucks and trailers can load and unload under their own power, rapid cargo handling is possible.
This transportation method has attracted attention as a form of “modal shift,” which refers to switching to transportation modes with lower environmental impact, such as ships or railways.

• ・Mitigating driver shortages: Drivers can rest during the voyage, contributing to improved working conditions.

• ・Environmental consideration: CO₂ emissions are lower than those of truck transport.

Protecting the Future of the Seas: The Challenge of LNG-Fueled Ferries

The Sunflower is also deeply committed to environmental responsibility. At the forefront of this effort are LNG-fueled ferries that use cleaner energy. The first vessel, Sunflower Kurenai, achieved an approximately 25% reduction in CO₂ emissions compared with conventional heavy fuel oil vessels and received the Ship of the Year 2022 award in the Large Passenger Ship category. The latest vessel, Sunflower Kamuy, has further reduced CO₂ emissions by approximately 35% through the adoption of an advanced hull design and energy-saving equipment.

• • Approximately 25–35% reduction in greenhouse gas (CO₂) emissions
  • Nearly 100% reduction in SOx (sulfur oxides)

   

With the sister vessel Sunflower Pirka also entering service in July 2025, a four-vessel LNG-fueled ferry operation has been established domestically. This represents an important statement from the Sunflower of its commitment to preserving the beautiful seas and planet for future generations. The MOL Group aims to achieve net-zero emissions by 2050 and will continue contributing to the realization of a sustainable society.
