Japanese poetry spans over a millennium, evolving from ancient oral traditions to refined court poetry and concise haiku. This rich history reflects cultural shifts, from aristocratic waka to the popularization of haiku among all social classes during the Edo period. Key forms include waka, tanka, renga, and haiku, each with distinct structures and themes. Influential poets like Bashō and Shiki shaped these forms, while modern poets blend traditional elements with Western influences, creating a diverse poetic landscape.
