Clean Ocean Ensemble (COE) is a nonprofit organization based on Shodoshima Island, Japan.
We work in collaboration with local fishers, researchers, and citizens to tackle the pressing issue of marine debris through innovative solutions — including the development of ocean cleanup devices, data-driven visualization of marine waste, and recycling initiatives.

Since our founding, we have been supported by individuals, governments, and businesses who believe in our mission.

To further scale our impact and ensure long-term sustainability, we are now inviting companies and organizations to become our corporate partners.
By partnering with us, your company can contribute to solving one of the most urgent environmental challenges of our time — while also enhancing your brand, fulfilling your CSR objectives, and engaging your employees in meaningful action.

Let’s build a cleaner, healthier ocean — together.
