Dan Pearson and Midori Shintani talk about their new book Tokachi Millennium Forest, which tells the story of a remarkable garden that began over thirty years ago in Hokkaido, the most northerly of the islands that make up Japan.  This exemplary project puts nature at the heart of the human experience and it is a torch bearer for the environmental movement in Japan and the Far East.  It embodies a new strand of naturalistic gardening that relates closely to the immediate context while bringing together the culture, aesthetics and horticultural practices of East and West.
