In Nagasaki Prefecture, where a lot of marine debris washes ashore, Yasuhide Kumagawa, who returned to his hometown after various twists and turns, has risen up with the desire to recycle and reuse this waste.

​

Despite his strong passion, he faced the harsh reality that cleaning up requires human resources, materials, and funding, leading to days where he struggled to get things moving, working part-time jobs to get by.

He ended up being labeled as just a "trash-picking man."

​

Despite this, he started gathering allies, but faced a new reality: "It's hard to make this a profitable business," and "People are less likely to act without money involved."

​

Will he be able to reach the goal of recycling the waste? And can it be sustained economically?

​

Is it possible to continue doing "good for the ocean" based solely on passion?

​

In his 60s, a challenge from almost ground zero begins.
