 As the shogunate was confronted with discontent in the southern parts of the country, and foreign shipping was being fired at in violation of treaties, France participated to allied naval interventions such as the Bombardment of Shimonoseki in 1864 (9 British, 3 French, 4 Dutch, 1 American warships).Following the new tax treaty between Western powers and the shogunate in 1866, Great Britain, France, the United States and the Netherlands took the opportunity to establish a stronger presence in Japan by setting up true embassies in Yokohama.France built a large colonial-style embassy on northern Naka-Dōri street.
