■ Turning technology into seeds for Nature Positivity.
Created by Arnaur, a biotech company operating under the motto 'Beauty and Health for Humanity and the Earth,' 'FUYUSO' is an 'environmental art' born from Arnaur's research process. With micro and macro algae cultivation technology at its core, these 'lab-born' seaweeds aim to contribute to the restoration of marine forests currently being lost globally, the maintenance of biodiversity, and ultimately, nature positivity. The next location chosen by 'FUYUSO', which was born from Shibuya's street culture, is 'Aqua Park Kawagoe'—a new professional aquarium that reproduces ecosystems with advanced aquarium technology and proposes 'nature positivity' through the beauty of aquatic life. Going beyond the framework of ornamental plants, it proposes a next-generation healing experience that will surprise even the aesthetic eyes of aquarists, serving as a catalyst for turning attention toward global environmental regeneration.

■ Product Features: The Art of Silence and Breathing
1. Floating Algae
The most prominent feature of 'FUYUSO' is its 'floating sensation', where algae continue to drift inside the bottle like smoke or clouds. Rather than mixing uniformly, they remain while drawing organic shades, resembling a living abstract painting that changes expression depending on the viewing angle.
2. 'Breathing Bubbles' that Visualize Photosynthesis
When bathed in light, 'FUYUSO' slowly performs photosynthesis. Occasionally, microscopic oxygen bubbles are born, and you can observe them sparkling as they rise to the water's surface. It seems still, but it is certainly alive. Its quiet life activity also regulates the breathing of the beholder.
3. An 'Urban Oasis' with Reduced Environmental Impact
No soil is used, and frequent watering is unnecessary. Just by placing it in a corner of a desk, a living room, or any place where light shines through, the space transforms into a healing environment resembling a small aquarium.
