Ginaku-ji means Temple of the Silver Pavilion in Japanese. (Yes speaking Japanese is one of the many talents I've hidden from you) The Silver Pavilion is the pretty structure at right, which he used to make his tea. If you're wondering why the pavilion doesn't look silver, it's because during his long retirement, the shogun was so busy making tea and gazing at the moon that he never found time to cover the pavilion with silver leaf, the original plan.
