The North Pacific Sea Route serves as a crucial maritime corridor that facilitates trade between North American and Asian economies. It connects ports on the west coast of North America—such as Vancouver, Seattle, Portland, San Francisco, and Los Angeles—to significant Asian ports including Yokohama, Kobe, Shanghai, Hong Kong, Manila, and Singapore. One of the primary advantages of this sea route is the direct navigation path following the Great Circle, which reduces the travel distance from Vancouver to Yokohama to approximately 2,480 km, thereby enhancing efficiency in transportation and trade. This route's significance is underscored by its role in the exchange of goods and services between two of the world's largest trading regions, contributing to a global economy that relies heavily on maritime shipping.
