Kurofune Soap: Crafting Clean Futures from Used Cooking Oil

What if your daily soap told a story?

Kurofune Soap blends Yokohama’s rich port history with today’s circular mindset. Crafted from used cooking oil collected locally, these handmade soaps aren’t just eco-friendly—they’re conversation starters.

Each bar is shaped like the iconic “black ships” (Kurofune), connecting the past and present through a refreshing, sustainable experience.

Take a look at how this playful yet practical project is cleaning up waste—and making waves.
