A lieutenant in the Imperial Russian military, he was commissioned to lead an expedition to Japan in 1791, returning two Japanese castaways to their home country in exchange for trade concessions from the Tokugawa shogunate.
[1] Unlike previous foreign visitors, Laxman was treated hospitably, but this changed when he demanded, imprudently, that he be able to deliver the castaways (Daikokuya Kōdayū's party) to Edo (modern-day Tokyo) in person.
He was soon met by two envoys and five hundred men, sent from Edo by senior councilor Matsudaira Sadanobu, who attempted to delay or prevent Laxman's traveling much deeper into Japanese territory.
Laxman refused, and ultimately was allowed to sail, with Japanese naval escort, to the port of Hakodate; from there, 450 Russians and Japanese would march to Matsumae Castle.Oddly, despite his impudence, Laxman was granted lavish Western-style living quarters; they were allowed to ignore the custom of kneeling and bowing before the Shogun's envoys, and were presented with three samurai swords and a hundred bags of rice.
[2] Laxman returned to Russia essentially empty-handed, though he held (quite possibly) the first official Japanese documents granting permission to trade, to a nation other than China, Korea or the Netherlands.
