Brand Story
The founder, Takahashi, started working in the fishing industry at the age of 16, taking on a part-time job filleting fish.
During this time, he noticed that a significant portion of the fish was discarded during processing, with about 60–70% of each fish being wasted to produce sashimi.
Moreover, fisheries had to pay to dispose of this waste.
This situation raised questions in his mind, and he began to wonder, "Is there a way to make use of this waste?"
One day during his university years, he came across a fish taxidermy display at a local fishing gear shop.
Though he had overlooked such things in the past, he was struck by the beauty and strength of the mounted fish and became curious about taxidermy.
Upon researching the topic, he learned that taxidermy involves methods similar to leather tanning.
At that moment, the idea struck him: “What if I could make wallets out of fish leather?”
Inspired by this thought, he began experimenting and researching.
Since there was no readily available information or stores specializing in fish leather at the time, he taught himself the general process of leather tanning and conducted countless experiments to apply it to fish skin.
After about a year of research and trial and error, he successfully developed a "fish leather" that met his expectations.
Despite numerous failures along the way, with the help and support of many, he was able to launch the brand in 2021.
