With Japan’s unprecedented modernization in the last century, the demand for traditional boats (wasen) faded, leaving the last generation of boatbuilders with no one to teach. This is the story of the author’s apprenticeships with five Japanese masters to build their unique and endangered traditional watercraft. Brooks was the sole apprentice for each craftsman, and worked under a time-honored system in which apprentices first swept floors and sharpened tools, learning chiefly by observation with only limited direct instruction. The resulting book is part ethnography, part instruction, and part the personal story of a wooden boatbuilder fueled by a passion to preserve a craft tradition on the brink of extinction. It fills a large and long-standing gap in the literature on Japanese crafts, and will be of interest to boatbuilders, woodworkers, and all those impressed with the marvels of Japanese design and workmanship.
