The Treaty of Amity and Commerce between France and Japan (Japanese: 日仏修好通商条約) (1858) opened diplomatic relations and trade between the two counties.
The treaty was signed in Edo on October 9, 1858, by Jean-Baptiste Louis Gros, the commander of the French expedition in China, assisted by Charles de Chassiron and Alfred de Moges, opening diplomatic relations between the two countries.
[1] The Treaty was signed following the signature of the Harris Treaty between the United States and Japan, as France, Russia, Great Britain, and Holland quickly followed the American example: Japan was forced to apply to other nations the conditions granted to the United States under the "most favoured nation" provision.
[2] The most important points of these Unequal Treaties were: In 1859, Gustave Duchesne de Bellecourt arrived and became the first French representative in Japan.
The ratified Treaty was brought to the shōgun by Duchesne de Bellecourt, on February 4, 1860.
