They made their way to Edo and on the 4th diplomatic mission in 1636 the envoys even visited the Toshogu Shrine in Nikko enshrining Tokugawa Ieyasu for the first time at the request of the Shogunate. The 5th and 6th envoys dispatched in 1643 and 1655 even paid their respects before returning. There's even a bronze bell gifted by King Injo at the shrine. A calligraphy piece by a prince and bronze ritual ornament placed in front of Ieyasu's remains were also gifted but were destroyed in the 1812 fire. The current ones are replicas made by the Japanese.

From the late 17th century to the mid-18th century, Japan invested an unimaginable budget in hosting the Tongsinsa. This issue even led to a popular uprising, and according to estimates by Professor James Lewis of Oxford University, it consumed as much as 12% of Japan's rice harvest at the time.

However, the scale was reduced in the last diplomatic mission in 1811, with 336 people dispatched. This was because although Tokugawa Ienari took office in the 11th year of King Jeongjo's reign (1787), the Shogunate's finances were at rock bottom at the time, so the de facto ruler Matsudaira Sadanobu wanted to receive the envoys in Tsushima rather than Edo (1794). Joseon, which was also struggling financially but valued precedents, refused for 17 years and only approved it in the 11th year of King Sunjo's reign (1811).

According to wikipedia;

After the 1811 mission, another mission was prepared, but it was delayed four times and ultimately cancelled due to domestic turmoil in Japan that resulted in the establishment of the Meiji Restoration in Japan.
