The main foreign policy event of the sleepy Alexey Orlov Era was start of the Russian colonisation of Japan, despite the First Japanese Expedition started as the as the last war of Mikhail Orlov.
In August 1847, after the execution of several Russian sailors, who were shipwrecked off the coast of Honshu, by the Japanese, Russia declared war on Japan. The Russian expeditionary force landed on the island of Ezo. The Mitraleses made it possible to cope with the samurai quickly enough, and by the summer of 1848 it became clear that Japan had lost the war. The shogun was forced to sign a humiliating peace, give up the Kuril Islands, Sakhalin and Ezo to the possession of Russia.
Defeat in the war released a long-overdue dissatisfaction with the Tokugawa rule. The southern daimyo, who had been in a subordinate position since the 17th century, revolted. By 1851, civil war was raging in Japan. And Russia did not fail to take advantage of this.
In June 1851, the Russian ambassador to Japan, Golovin, concluded an agreement with the shogun, and Russian troops landed on the territory of the island of Honshu. Now the Russians acted as allies of the Tokugawa, quickly enough for the shogunate to turn the tide of the war in their favor. In 1852 Russia, France and Great Britain formally conclude an agreement on the division of Japan. Most of the country remains under nominal Tokugawa rule and a Russian protectorate. On the island of Kyushu, a state emerged as a separate republic of Kyushu - the state of the southern daimyo under the protectorate of France. The islands of Okinawa passed under the protectorate of Great Britain. This is how Japan entered its colonial era.
The Russian authorities saw Japan as "our India" - a developed eastern colony, a military base and a sales market. President Annenkov decided to use Japan as a source of human resources for the development of Siberia and the Far East. First of all, the Ronins - samurai, who remained without a suzerain and without work after all the wars, were resettled on Amur. By 1860, the Japanese Cossacks were created on the Amur - 10 thousand ronins (in fact, not all of them were samurai) settled on the border with China, and 4 Cossack regiments were created from them under the command of Russian officers. Later, the export of workers from Japan to Siberia began.
By the beginning of the twentieth century, the Japanese diaspora spread throughout Russia up to Kazan (children of Japanese daimyo study at Kazan University), but most of all in Eastern Siberia - Irkutsk, Chita, Vladivostok. Zen Buddhism, opium and yakuza come to Russia along with the Japanese. By 1900, the yakuza are operating throughout Siberia. On the other hand, Christianity is coming to Japan. Since 1860, Saint Nikolai Kasatkin has been preaching in Japan, a man, who creates the Japanese alphabet based on the Cyrillic alphabet and the Japanese Orthodox Church.
