Issey Miyake (三宅 一生, Miyake Issei^?, born 22 April 1938) is a Japanese fashion designer. He is known for his technology-driven clothing designs, exhibitions and fragrances.

Miyake was born 22 April 1938 in Hiroshima, Japan. As a seven year-old, he witnessed and survived the atomic bomb dropped on Hiroshima on August 6, 1945. He studied graphic design at the Tama Art University in Tokyo, graduating in 1964. After graduation, he worked in Paris and New York City. Returning to Tokyo in 1970, he founded the Miyake Design Studio, a high-end producer of women's fashion.

In the late 1980s, he began to experiment with new methods of pleating that would allow both flexibility of movement for the wearer as well as ease of care and production. This eventually resulted in a new technique called garment pleating in 1993's Pleats Please in which the garments are cut and sewn first, then sandwiched between layers of paper and fed into a heat press, where they are pleated. The fabric's 'memory' holds the pleats and when the garments are liberated from their paper cocoon, they are ready-to wear. He did the costume for Ballett Frankfurt with pleats in a piece named "the Loss of Small Detail" William Forsythe and also work on ballet "Garden in the setting".
