amu Inc. (Headquarters: Kesennuma City, Miyagi Prefecture; Representative Director & CEO: Kodai Kato, hereinafter "amu"), which develops new products by upcycling discarded fishing gear, together with Fish Hook Inc. (Headquarters: Saitama City, Saitama Prefecture; Representative Director & CEO: Ryoji Takeda, hereinafter "Fish Hook"), will sell carabiners made from used fishing lines collected at a previous pop-up event. These will be available at the POP UP event "Fish Hook Spring Collection’26" held at Shinjuku Takashimaya for four days from April 3 (Fri) to April 6 (Mon), 2026. Featuring a unique one-of-a-kind marble pattern, a new limited-edition color will also be introduced this time.
At the venue, there will also be fishing line collection and the sale of tote bags, T-shirts, and sunglasses using amuca®, a nylon derived from fishing nets.
This initiative is part of a demonstration experiment for upcycling discarded fishing lines that has been implemented since April 2025. In addition, by expanding the target audience to non-anglers, it provides an opportunity to protect the ocean through circular actions that people can participate in on the spot, rather than just learning about the marine debris problem.
Moving forward, amu aims to recycle local discarded fishing gear by developing and selling products upcycled from various types of waste.
## Circular actions combined with "shopping." From the fishing line upcycling project launched in 2025 to product sales.
While opportunities to hear and see news about the marine debris problem are increasing, there are not many "entry points" for individuals to participate in their daily lives. In this POP UP, situated within the daily flow of consumers at a department store, we will conduct the "Fishing Line Collection Project" and sell products upcycled from collected fishing lines as a "circular action" that both anglers and non-anglers can easily engage in. Additionally, along with fishing lines, we will sell tote bags, T-shirts, and sunglasses using amuca®, a nylon derived from fishing nets collected from fishermen in Kesennuma City, Miyagi Prefecture.
By turning collected fishing lines into resources for the next products, we visualize a cycle that goes beyond just "knowing," providing visitors with an experience where their small actions connect to the future of the ocean.
## Upcycling used fishing lines collected at the previous POP UP into "one-of-a-kind" limited carabiners
The limited-edition carabiners sold this time are upcycled from used fishing lines collected at the previous POP UP (held in November 2025). By turning the collected fishing lines into products, we have given shape to a cycle that does not just "end with collection."
The collected fishing lines were mixed with marine debris washed ashore in Tsushima City, Nagasaki Prefecture, and handcrafted by BLOOP LLC (Headquarters: Fujisawa City, Kanagawa Prefecture; Representative: Shun Watanabe, hereinafter "BLOOP"). The marble patterns, which make use of the materials, have different expressions, making each piece a unique "one-and-only" item.
By reusing unusable fishing lines as materials, we aim to achieve both the reduction of environmental impact and the creation of new value. At the same time, by clearly conveying the story from "fishing line collection" to "productization" at the storefront, we turn environmental issues from a distant concept into a catalyst for action.
