He served as interpreter, mediator, and in several other capacities in negotiations which resulted in the conclusions of treaties or conventions signed between the Tokugawa shogunate and the United States, Russia, and the United Kingdom in 1854-1855;[1] he also played a primary role in the negotiation and conclusion of the Dutch-Japanese Treaty of Peace and Amity in 1856.[1] Meanwhile, in 1855, he was named Dutch consul (rijikan).[2]
In 1854-1855, Curtius also arranged for the Dutch warship Soembing (later renamed Kankô-maru) to be gifted to the shogunate, and for Dutch naval officers to provide training in the operation of the warship to shogunate retainers.[3]
