Self-taught artist Akira Nagaya has mastered the Japanese art of kirie, or delicate paper cutting. Interestingly, the artist began his career as a 20-something sushi decorator. His job entailed cutting slices into bamboo leaves. As practice, he would go home and use a utility knife to carve various patterns into paper. Now, the 47-year-old's paper-cut designs are so intricate that many of them look like thin ink scribbles.
