Yamaguchi Prefecture is at the western end of Honshu and is surrounded by the sea on three sides. It was the land of the Choshu Domain, which drove the Meiji Restoration, and many activists of that time came from Hagi. The prefecture has many sights, such as fugu (pufferfish) in Shimonoseki, the Kintai Bridge and the karst plateau of Akiyoshidai.
