備前国 (Bizen no Kuni) was a historical province in Japan, located in the western part of the country, primarily in what is now Okayama Prefecture. It was known for its rich culture and history, particularly during the Edo period. The region was famous for its production of Bizen pottery, one of Japan's oldest and most esteemed ceramic styles. The province played a significant role in the development of the Japanese feudal system and was home to several important castles, including Okayama Castle. Its strategic location along the Seto Inland Sea facilitated trade and cultural exchange, contributing to its economic prosperity throughout the centuries.
