In 1950, Japan began to rebuild and expand its distant-water fishing fleets, particularly focusing on tuna and squid longline fisheries in the wake of World War II. This expansion was crucial for Japan's economic recovery and food security, allowing the nation to re-establish itself as a major player in the global fishing industry. The growth of Japan's fishing capabilities also raised discussions about sustainable fishing practices and international fishing rights.

The expansion of Japanese distant-water fishing in 1950 reflected themes of post-war recovery in East Asian literature. Poets explored the relationship between culture, resource management, and the ocean, highlighting the complexities of modern existence and the interconnection of human endeavors with nature.
