Kenya Hara (born 1958) is a Japanese graphic designer and curator. He is a graduate of Musashino Art University.
Hara has been the art director of Muji since 2001 and designed the opening and closing ceremony programs of the Nagano Winter Olympic Games 1998. He published Designing Design, in which he elaborates on the importance of “emptiness” in both the visual and philosophical traditions of Japan, and its application to design. In 2008, Hara partnered with fashion label Kenzo for the launch of its men's fragrance Kenzo Power.
Hara is a leading design personality in Japan and in 2000 had his own exhibition “Re-Design: The Daily Products of the 21st Century”.
The reader should be aware that this isn't the definitive conceptual exploration of the "ex-formation" concept (though that's an oxymoronic goal if there ever was one), but is instead a collection of student projects to explore various subjects with "ex-formation" like strategies. I think Kenya Hara is very kind to put the spotlight on the students in this way, and indeed the work is very delightful and thought provoking, like a good contemporary art museum visit.
I think that Designing Design (https://www.goodreads.com/review/show...) as a masterful survey of Kenya Hara's work, including the ex-formation concept, and not only has sufficient coverage of those ideas, but places it in the context of Hara's broader work, and I would actually start there to understand what ex-formation is all about. If you're looking for a lighter introduction to Kenya Hara, I would start with White (https://www.goodreads.com/review/show...) as a well-contained masterpiece.
Once you read these, and want to see how the ex-formation concept is extended from year-to-year, this book is a great follow-up.
