Awaji Island
Japan's first island according to Kojiki mythology and the birthplace of Awaji onions — the sweetest in Japan. The island sits between Osaka Bay and the Naruto Strait where powerful whirlpools form. The northern tip connects to Kobe via the Akashi Kaikyo Bridge (world's longest suspension bridge). The western coast has beaches and onsen resorts.

Arima Onsen
Japan's oldest recorded hot spring resort — mentioned in 8th-century chronicles and praised by Toyotomi Hideyoshi as his favourite retreat. The town has two unique spring types: Kinsen (golden-iron water that turns rusty on contact with air) and Ginsen (radium-bearing clear water). Both are found nowhere else in the region.
Himeji Castle
Japan's finest surviving feudal castle — a UNESCO World Heritage site nicknamed the "White Heron Castle" for its dazzling white plastered walls. Built in 1609 and never destroyed by war, earthquake, or fire, it stands exactly as it was 400 years ago. The six-storey keep and 83 connected buildings form the largest castle complex in Japan.
Kinosaki Onsen
A classic Tajima hot spring town where a willow-lined canal connects seven public bathhouses — each with a distinct architectural style and character. Guests wear yukata robes to walk between baths (soto-yu meguri), an Edo-period tradition still alive today. Snow crabs in winter make this one of Japan's finest ryokan destinations.
