Overview: This time on Japanology Plus, our theme is Japanese gardens, compact evocations of nature's majesty. Japan has many garden styles: from tea gardens, to the dry gardens of Zen Buddhism, to the pocket gardens of city-dwellers. Our expert guest is Takahiro Naka, a professor of garden history who is actively involved in garden design and restoration projects around the country. And in Plus One, a Japanese rock garden that fits on your tabletop.
