Emperors and shoguns
Japan traces an imperial line it regards as unbroken, though real power often lay elsewhere. From the twelfth century military rulers called shoguns governed in the emperor's name, and a warrior class, the samurai, dominated society. The Tokugawa shogunate, established in 1603, brought more than two centuries of peace and near-total isolation from the outside world.
In that closed era Japan developed its own refined culture: the tea ceremony, haiku, kabuki theatre, woodblock prints and Zen Buddhism. Foreign contact was banned on pain of death, and Christianity was suppressed.
The Meiji leap
American warships forced the country open in 1853. The shock toppled the shogunate, and the Meiji Restoration of 1868 returned power to the emperor and launched a deliberate crash-modernisation. Japan studied Western industry, law and armies, built railways and factories, and within decades defeated China and then Russia in war.
That power turned imperial and then catastrophic: colonisation of Korea and Taiwan, the invasion of China, and the Pacific War, ending in the atomic bombing of Hiroshima and Nagasaki and surrender in 1945. Under a US-drafted constitution Japan renounced war and rebuilt at astonishing speed.
Japan and Africa
Post-war Japan became a major source of development finance, and from 1993 it built its African engagement around TICAD, the Tokyo International Conference on African Development. Held every few years and co-organised with the United Nations and others, TICAD channelled Japanese aid, infrastructure loans and private investment toward the continent.
Japanese firms are long-standing presences in African markets — Toyota and other carmakers, trading houses in resources and ports — and Japan has used TICAD partly to distinguish its approach, emphasising quality infrastructure and human-capital training, from that of larger rivals. Its footprint is smaller than China's, but its aid programmes are among the oldest.
