Nowhere in the world does the interior design of a shop influence sales as it does in Japan. Retailers spare no trouble or expense when planning and realising the design or renovation of their premises. PowerShop presents the best and most recent retail designs by ten Japanese interior architects. Shops and showrooms created for established names like Issey Miyake, Yohji Yamamoto and Nissan share centre stage with numerous smaller, cutting-edge boutiques. The designers presented here prove that a shop can resemble an art installation and still be successful. They prove that it pays to invest in creativity. And they certainly prove that in Japan imagination reigns. The author Carolien van Tilburg is a Dutch journalist and media producer who has lived in Japan since 1995.
