I read this 'Japanese corporate novel' nine years ago, and it has sat on my shelves since that time...I've not thrown it away because I was so smitten by it.
The translation - despite the threat of dull subject matter - it lively and fresh. And despite the changes in the Japanese situation over the last decade (remember when we thought Japanese global economic domination was an inevitability?), the applicability of the novel remains fully in force today. It gets to the heart of every Japanese 'salaryman' & their internal struggle with their acceptance of that lifestyle vs. their deeply internalized entrepreneurial yearnings.
The breakthrough achieved by the book's protagonist, Nakasato, and the misery that befalls his one-time officemate Ojima, might seem mundane on the surface, but surely strike the average Japanese worker like a tremendous blow to the chest.
Really top-notch stuff and far better than any dry non-fiction, treatise in delivering insight into the Japanese business mind.
