Differences in the treatment of envoys after the Imjin War
After the Imjin War (1592–1598), diplomatic relations between Joseon and Japan resumed under the Tokugawa Shogunate with drastically different dynamics.
The Shogunate treated the Korean Tongsinsa envoys with extravagant hospitality—often spending up to a million ryō on receptions to showcase the Shogun's prestige and legitimacy.
In contrast, a deeply cautious Joseon strictly confined all Japanese envoys to the Waegwan (the Japanese enclave in Busan/Choryang), completely banning them from stepping outside or ever traveling inland to the royal capital.
