Yamaguchi Prefecture occupies the westernmost tip of Honshu, where the Sea of Japan and the Seto Inland Sea nearly meet across a narrow peninsula. It is best known for the vivid red torii tunnel of Motonosumi Shrine, the preserved samurai streets of Hagi, one of Japan's three finest wooden bridges at Kintaikyo, and Shimonoseki, the country's capital of pufferfish (fugu) cuisine facing the Kanmon Strait.
Yamaguchi is among Japan's safest and least-crowded prefectures for international travellers. Violent crime is virtually nonexistent and even petty theft is rare, including in the busier Shimonoseki waterfront and Hagi's historic streets. The main hazards are weather-related — Sea of Japan winter conditions on the northern coast, typhoon exposure in late summer and early autumn, and coastal currents at swimming spots and cliffside shrines such as Motonosumi.
