On the morning of 19 November 2025, a special atmosphere lay over the Yokosuka naval base. The Japanese observation vessel Shirase was preparing to begin its journey to one of the most inhospitable yet fascinating regions on Earth. For the crew, their families, and everyone involved, this moment was far more than the departure of a ship, it marked the beginning of an adventure filled with responsibility, courage, and determination.
Around 500 people had gathered on the quay to see off the men and women of the Shirase. Amid conversations, there was a palpable sense of tension, but also pride. Children waved small flags, partners held each other tightly, and relatives tried to hide their emotions behind brave smiles. The departure ceremony was a reminder that every expedition is also a journey for those who stay behind.
As the crew boarded and the final preparations were completed, an almost ceremonial silence settled over the harbor for a brief moment. Then the Shirase slowly began to pull away from the quay. Its engines hummed powerfully, yet the farewell was gentle, interrupted only by shouts, waves, and the sound of the water parting around the hull. At around 11:30 a.m., the ship finally disappeared behind the harbor wall, followed by hundreds of gazes that lingered long after it was gone.
This year, for the first time, an observer from the Yokosuka Air Base is accompanying the journey to further strengthen cooperation between the different units, a small detail that illustrates the complexity and significance of this mission.
The next major milestone will come on 4 December, when the Shirase reaches Fremantle, Australia. There, scientists arriving by air will join the crew before the ship sets course for Antarctica.
With its departure, the Shirase carries not only equipment and people on board, but also the hope for new insights, the spirit of research, and the wishes of all those who came to see it off. Its journey reminds us of the courage required to explore the unknown, and of the strong bonds that connect people, even when the sea lies between them.
