The Japan Society's newest newsletter brings word of this event:
The Tokugawa Era (1603-1868), brought three centuries of peace to Japan. In The Edo Inheritance, Tsunenari Tokugawa, the eighteenth head of the Tokugawa family, argues that the unique cultural values fostered during the Tokugawa Era have much to offer the world in an age of globalization and uncertainty.
I haven't read the book, although a cursory examination of reviews from various places (e.g., The Japan Times) make me think it is more inspired by an impulse towards cultural rehabilitation than scholarly thought — more Shintaro Ishihara than G.B. Sansom, if you get my drift. I'll probably check it out at some point, but I plan to keep a 55-gallon barrel of salt handy.
The title brought to mind The Shogun Inheritance, a glossy book issued in conjunction with a BBC-TV series on Japan back in 1980 or so. A decent introduction for beginners, but more notable for the photography than for its insights or analysis, which are already dated in more ways than one.
