Hagakure is a treatise on the samurai code written by Yamamoto Tsunetomo, an eighteenth-century samurai. It's a guide, organized as a loose collection of thoughts, on how samurai should conduct themselves. This philosophy--bushido, or "the way of the samurai"--is, according to Tsunetomo, essentially a Way of death or dying. This embracing of death with honor and courage is the core theme of Hagakure--and part of its allure.
