Description & Facts: Hiroshima served as the capital of Hiroshima Domain during the Edo period. After the han was abolished in 1871, the city became the capital of Hiroshima prefecture. Hiroshima became a major urban center during the Meiji period as the Japanese economy shifted from primarily rural to urban industries. Ujina Harbor was constructed in the 1880s, allowing Hiroshima to become an important port city. The Sanyo Railroad was extended to Hiroshima in 1894, and a rail line from the main station to the harbor was constructed for military transportation during the First Sino-Japanese War. New industrial plants, including cotton mills, were established in Hiroshima in the late 1800s. Further industrialization in Hiroshima was stimulated during the Russo-Japanese War in 1904, which required development and production of military supplies. The Hiroshima Prefectural Commercial Exhibition Hall was constructed in 1915 as a center for trade and exhibition of new products. Later, its name was changed to Hiroshima Prefectural Product Exhibition Hall, and again to Hiroshima Prefectural Industrial Promotion Hall.
