, a famous samurai of the Bakumatsu period. He was later appointed as the chief of the Seieitai, an elite bodyguard for the 15th Shōgun
Tokugawa Yoshinobu. Belligerent opposition to Western influence further erupted into open conflict when the
Emperor Kōmei, breaking with centuries of imperial tradition, began to take an active role in matters of state and issued, on March 11 and April 11, 1863, his . The Mōri clan of
Chōshū, under Lord
Mōri Takachika, followed on the order, and began to take actions to expel all foreigners from the date fixed as a deadline (May 10, Lunar calendar). Openly defying the shogunate, Mōri ordered his forces to fire without warning on all foreign ships traversing
Shimonoseki Strait. Under pressure from the Emperor, the Shogun was also forced to issue a declaration promulgating the end of relations with foreigners. The order was forwarded to foreign legations by Ogasawara Zusho no Kami on June 24, 1863:
Edward Neale, the head of the British Legation, responded on very strong terms, equating the move with a declaration of war: File:Yokohama-Sumo-Wrestler-Defeating-a-Foreigner-1861-Ipposai-Yoshifuji.png|An 1861 image expressing the

Foreign military interventions against American influence, which had been of high importance in the beginning, waned after 1861 due to the advent of the
American Civil War (1861–1865) that monopolized all available U.S. resources. This influence would be replaced by that of the British, the Dutch and the French. The two ringleaders of the opposition to the were from the Satsuma (present day Kagoshima prefecture) and Chōshū (present-day Yamaguchi prefecture) provinces, two of the strongest anti-shogunate domains in Edo-period Japan. Satsuma military leaders
Saigō Takamori and
Okubo Toshimichi were brought together with
Katsura Kogoro of Chōshū, notably through the efforts of
Sakamoto Ryōma. As the former happened to be directly involved in the murder of Richardson, and the latter in the attacks on foreign shipping in Shimonoseki, and as the declared itself unable to placate them, Allied forces decided to mount direct military expeditions. In the morning of July 16, 1863, under sanction by Minister Pruyn, in an apparent swift response to the attack on the
Pembroke, the U.S. frigate
USS Wyoming under Captain McDougal sailed into the strait and single-handedly engaged the U.S.-built but poorly manned fleet. For almost two hours before withdrawing, McDougal sank one Japanese vessel and severely damaged the other two, along with some forty Japanese casualties, while the
Wyoming suffered extensive damage with fourteen crew dead or wounded. Image:ShimonosekiWyomingAttacks.jpg|The

Tancrède and the
Dupleix, and 250 men under Captain
Benjamin Jaurès swept into Shimonoseki and destroyed a small town, together with at least one artillery emplacement. In August 1863, the Bombardment of Kagoshima took place, in retaliation for the
Namamugi incident and the murder of the English trader Richardson. The
Royal Navy bombarded
Kagoshima and sank several ships. Satsuma however later negotiated and paid 25,000 pounds, but did not remit Richardson's killers, and in exchange obtained an agreement by Great Britain to supply steam warships to Satsuma. The conflict actually became the starting point of a close relationship between Satsuma and Great Britain, which became major allies in the ensuing
Boshin War. From the start, the
Satsuma Province had generally been in favour of the opening and modernization of Japan. Although the Namamugi Incident was seen as unfortunate, it was taken not to be characteristic of Satsuma's policy, and was instead branded as an example of anti-foreign sentiment, as a justification to a strong Western show of force.

daimyō Mōri Takachika of the
Chōshū Domain based in
Shimonoseki, Japan. This conflict proved inopportune for America, which in 1864, was already torn by its
own civil war. Image:Choshu-Battery-Capture-Shimonoseki-1864.jpg|The

French Navy troops taking possession of Japanese cannons at Shimonoseki Following these successes against the imperial movement in Japan, the shogunate was able to reassert a certain level of primacy at the end of 1864. The traditional policy of
sankin-kōtai was reinstated, and remnants of the rebellions of 1863–64 as well as the
Shishi movement were brutally suppressed throughout the land. The military interventions by foreign powers also proved that Japan was no military match against the Allies. The
sonnō jōi movement thus lost its initial impetus. The structural weaknesses of the Bakufu however remained an issue, and the focus of opposition would then shift to creating a strong government under a single authority.
Mito Rebellion On 2 May 1864, the
Mito rebellion erupted against the power of the shogunate in the name of the
sonnō jōi. The Shogunate managed to send an army to quell the revolt, which ended with the surrender of the rebels on 14 January 1865.
First Chōshū Expedition In the
Kinmon Incident on 20 August 1864, troops from
Chōshū Domain attempted to take control of Kyoto and the Imperial Palace in order to pursue the objective of
Sonnō Jōi. This also led to a punitive expedition by the Tokugawa government, the
First Chōshū expedition.
Hyōgo Naval Expedition As the Bakufu proved incapable to pay the $3,000,000 indemnity demanded by foreign nations for the intervention at Shimonoseki, foreign nations agreed to reduce the amount in exchange for a ratification of the Harris Treaty by the Emperor, a lowering of customs tariffs to a uniform 5%, and the opening of the harbours of Hyōgo (modern
Kōbe) and
Osaka to foreign trade. In order to press their demands more forcefully, a squadron of four British, one Dutch and three French warships were sent to the harbour of Hyōgo in November 1865. Other displays of force were made by foreign forces, until the Emperor finally agreed to change his total opposition to the Treaties, by formally allowing the
shōgun to handle negotiations with foreign powers. An agreements providing for the tariff revision was signed in June 1866. These conflicts led to the realization that head-on conflict with Western nations was not a solution for Japan. As the Bakufu continued its modernization efforts, Western
daimyōs (especially from Satsuma and Chōshū) also continued to modernize intensively in order to build a stronger Japan and to establish a more legitimate government under Imperial power.
Second Chōshū Expedition The shogunate led a second punitive expedition against Chōshū from June 1866, but the shogunate was defeated by the more modern and better organized troops of Chōshū. The new
shōgun Tokugawa Yoshinobu managed to negotiate a ceasefire due to the death of the previous
shōgun, but the prestige of the shogunate was nevertheless seriously affected. This reversal encouraged the Bakufu to take drastic steps towards modernization. == Downfall of the Tokugawa shogunate (1867–69) ==
