Japanese billionaire Yusaku Maezawa recently traveled to Hamburg in his black and gold Bombardier Global 7500 business jet before transferring to a helicopter to attend the much-anticipated launch of his new superyacht, Cosmos. The event marked a personal milestone for the entrepreneur who commissioned the vessel six years ago, and who has been documenting its progress with great anticipation.
On Instagram, Maezawa shared videos and photographs of the yacht that immediately captured attention for its futuristic form and striking features. His captions expressed excitement that the 114-meter vessel, built by the German yard Lürssen, will be delivered next spring once its interior is complete.
Among the images, one detail stood out above all: the glass-domed owner’s office, a space that reflects both the ambition of the project and the personal tastes of its owner. It is a private study with a sky terrace, topped by an uninterrupted dome engineered from thick, bent glass.
Lürssen developed a custom process to achieve the structure without distortions, ensuring a seamless 360-degree view across sea and sky, as reported by the Yachtingmagazine. The office elevates the concept of a workspace at sea into something closer to a sanctuary, one that allows Maezawa to surround himself with horizon lines while enjoying solitude above the decks.
The design resonates with Maezawa’s fascination with technology and with Apple in particular. Known as a devoted Apple user, he has often said he prefers working directly from his iPhone rather than from a traditional computer.
During his 2021 trip to the International Space Station, he shot time-lapse videos and images of Earth on his iPhone 12, a detail widely reported in Japanese tech media. It feels fitting, then, that his yacht carries a signature feature that echoes Apple’s obsession with glass as a medium of architectural identity.
Apple Park in Cupertino was famously built around the world’s largest curved glass panels, and the Fifth Avenue flagship in New York is defined by its glass cube. Cosmos’ domed study takes that same spirit of ambitious glazing, scaling it to a private environment on the ocean.
Marc Newson, who designed both the exterior and interior of Cosmos, has long favored organic forms, soft transitions, and the extensive use of transparency. His continuous glazing on the yacht’s superstructure, combined with the dome, creates a smooth silhouette with almost no sharp edges. This design language connects directly with his past collaborations with Jony Ive at Apple. Newson joined Ive’s design team in 2014 and co-created limited edition (RED) projects such as the Leica M camera, an aluminum desk, and a vivid red Mac Pro. All of those objects shared a materials-driven philosophy and an obsession with seamless surfaces. Cosmos feels like the most ambitious extension of that ethos yet, a megayacht conceived as a single sculptural form.
A superyacht built for adventure and innovation
Beyond its iconic dome, Cosmos has been engineered as a vessel that combines artistry with functionality. With a steel hull and ice-class 1D reinforcement, it is capable of operating in light ice conditions, making it suitable for voyages into the Arctic or Antarctic. Maezawa specifically requested a yacht that could travel anywhere in the world, and Lürssen delivered with structural reinforcements and advanced systems to withstand harsh environments.
Cosmos also carries the hallmarks of a true expeditionary platform. It comes with a submarine capable of diving to 200 meters, a dedicated fishing boat for offshore pursuits, a helipad above the foredeck, and a vast aft deck with a pool, Jacuzzi, and tender bay. Every element has been chosen to allow Maezawa to pursue adventures on and below the water, while also offering luxurious spaces for leisure and reflection.
Yet the most groundbreaking aspect lies beneath its decks. Cosmos is Lürssen’s first superyacht powered by a methanol-to-hydrogen fuel-cell system, a milestone launched deliberately to coincide with the shipyard’s 150th anniversary in August 2025. The twin 500 kW fuel cells allow for around 15 days of zero-emission operation at anchor or 1,000 nautical miles of slow-speed cruising without generating exhaust gases. This makes Cosmos one of the cleanest large yachts ever built, pushing forward an industry where sustainability is becoming a defining priority.
Cosmos is not just another addition to the global fleet of gigayachts. It is an artistic and technological experiment that unites Maezawa’s personal passions with Lürssen’s engineering heritage. The glass dome encapsulates its ambition, turning a private office into a transparent beacon of design and craftsmanship. When Cosmos is finally delivered next spring, it will not only symbolize the culmination of a billionaire’s dream but also stand as one of the most original yacht projects of its era.
