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.

Wellness travel tips
Get the most from your wellness experience.
Wash and rinse thoroughly at the shower stations before entering any shared onsen bath
Keep the small modesty towel out of the bathwater and tie back long hair
Check tattoo policies before visiting traditional public bathhouses like Onto; private-bath ryokan rooms are a reliable alternative
Try the free ashiyu foot baths scattered through Yuda Onsen if short on time for a full bath
Book ryokan stays with meals included, as kaiseki dinner is typically part of the overall wellness experience rather than a separate charge
Visit in autumn or winter for a warmer contrast between the hot spring water and cool outside air, considered by locals to be the most pleasant bathing season
