A New Era of Maritime Innovation
Japan Marine United Corporation (JMU), a titan in Japan’s shipbuilding industry, has just unveiled its latest marvel: the Sakura Queen. This 181,000 dwt bulk carrier, delivered to Green Spanker Shipping, isn’t just another ship—it’s a testament to the future of eco-friendly maritime transport.
The handover ceremony took place on February 20, 2025, at JMU’s Ariake shipyard in Kumamoto, marking a significant milestone in sustainable shipping. With a length of 292 meters and a gross tonnage of 93,691 GT, the Sakura Queen is a behemoth of the seas. But its true power lies in its green credentials.
Cutting-Edge Technology for a Cleaner Ocean
The Sakura Queen is the seventh vessel in JMU’s N-181,000 dwt series, designed to meet Phase 3 of the Energy Efficiency Design Index (EEDI). This isn’t just a box-ticking exercise—it’s a leap forward in reducing the environmental impact of global shipping.
The ship is equipped with a state-of-the-art ballast water treatment system, which prevents the spread of invasive marine species by neutralizing organisms in ballast water. Additionally, it complies with stringent nitrogen oxide (NOx) Tier III emission standards, ensuring cleaner air as it traverses the oceans.
But what really sets the Sakura Queen apart is its energy-saving technology. JMU’s proprietary Super Stream Duct, Surf-Bulb, and ALV-Fin systems work in harmony to minimize resistance and maximize fuel efficiency. The result? A vessel that not only cuts costs but also slashes its carbon footprint.
A Month of Maritime Milestones
February 2025 has been a banner month for JMU. Just weeks before the Sakura Queen’s delivery, the company handed over the 211,981 dwt Mount Anjin to Singapore’s Eastern Pacific Shipping. And let’s not forget the SG Twilight, a dual-fuel LNG-powered bulk carrier delivered to Nippon Yusen Kabushiki Kaisha (NYK Line).
The SG Twilight is part of NYK Line’s Sail GREEN initiative, launched in 2022 to promote sustainable shipping. Its sister vessel, the SG Ocean, made history as the first Capesize LNG-fueled bulk carrier built in Japan. Together, these ships represent a seismic shift in the industry—one where sustainability is no longer optional but essential.
The Future of Shipping is Here
The Sakura Queen isn’t just a ship; it’s a symbol of progress. As the maritime industry grapples with the urgent need to reduce emissions, JMU is leading the charge with innovative designs and cutting-edge technology. The Sakura Queen proves that sustainability and efficiency can go hand in hand, paving the way for a greener, cleaner future on the high seas.
