Market Needs by Kosaku Kondo Published in 1988 by President Inc. 1300 yen Condition: Almost like new. Review: Mr. Kondo is a well-known figure as a management consultant. He is known in some circles as the originator behind many well-known hit products, but he doesn't appear publicly, so no one knows his name. This book is one of the few books he has written, and it is rare because it is hardly available.
