Leave it to Japan’s rich fish culture to conjure up an educational and kid-friendly 3D bluefin tuna puzzle that teaches you exactly how to dismantle a fresh catch.

Roughly the size of an iPhone 8, this 33-piece puzzle comes with a cutting board and maguro bōchō, a knife made only to butcher tuna. Dismantle the puzzle to learn which part is fatty tuna, medium fatty and fillets, plus you’ll learn what the organs look like and how to remove them. Practice your butchering skills on this puzzle and you’ll be ready to study under a real sushi chef in no time. Find it here on Amazon or at Japan Trend Shop.
