TSUSHIMA Knife born from Tsushima’s Marine Debris

Musashi's vision of the future

The Reality of Marine Debris

 DebrisEstimated marine plastic debris reached 8 million tons and continues to flow into the ocean yearly.According to the 2010 data from Science magazine, the cumulative total ocean waste has risen to 150 million tons by now. This data is already quite old, and the current volume is estimated to be considerably higher than this.

Musashi's Product Concept

Musashi‘s product concept is to create non-discardable products from discarded plastic. As a concrete means of achieving this, we have attempted to take plastic washed ashore as marine debris and transform it into beautiful artifacts and utility products.
