Suddenly, Masaatsu Naito of Yunagaya Domain receives an order to perform Sankin-kotai within 5 days. Sankin-kotai is a custom that requires the daimyo to visit the shogun in Edo. Unfortunately, the time needed to visit the shogun in Edo for Masaatsu Naito is 8 days. Masaatsu Naito also learns he received the order because a high ranking government official wants the gold mine. Also, the expense for Sankin-kotai is high and the Yunagaya Domain is such a small han that it seems impossible to complete. Nevertheless, Masaatsu Naito begins an unexpected operation to complete Sankin-kotai in 5 days.
