The Soembing was a Dutch ship sent by the King of the Netherlands to Nagasaki in 1854 and again in 1855, as part of arrangements by VOC factor Jan Hendrik Donker Curtius to provide naval and military training to shogunate troops as part of a broader set of treaty agreements.
The shogunate expressed to Curtius in 1853 interest in constructing a modern Japanese navy. Curtius corresponded with the Netherlands, and the Soembing arrived at Nagasaki the following summer, where its crew engaged in some limited training exercises. In July 1855, Curtius proposed that the Soembing be given as a gift to the shogunate, and that its crew train some number of Japanese sailors more extensively, but only in conjunction with a broader formal treaty between the two countries.
Curtius made his formal proposal for a commercial treaty on September 7 (7/26), and by February the following year, the Dutch-Japanese Treaty of Peace and Amity had been concluded.
