Notes on Meaning

• The idiom originates from historical contexts, especially in East Asian history, where rulers would literally close borders and ports (like in Japan during the Sakoku period or in China under certain dynasties) to control foreign influence.
• In contemporary usage, it is almost always metaphorical, criticizing policies or attitudes that reject international cooperation, trade, and exchange of ideas. It is not used for temporary closures (like a store closing) or personal solitude.
