Hiroshima is a city of peace and resilience. The Hiroshima Peace Park and Museum, designated a UNESCO World Heritage Site, vividly portrays the aftermath of the atomic bombing. Designed by Kenzō Tange and inaugurated in 1955, the museum serves as a global symbol of peace, featuring a solemn cenotaph bearing the victims' names and the Flame of Peace, lit in 1964. The Genbaku Dome stands as the sole original structure left at the blast site.

Famous for its fugu (also known as puffer or blowfish), Shimonoseki at the southwestern tip of Honsho, is surrounded on three sides by the ocean. The Japanese delicacy is available at Karato Ichiba fish market. Other attractions include Kozan-ji Buddhist temple, a ‘National Treasure of Japan’ that dates from 1327 and the photogenic 1,780-m-long Tsunoshima Bridge, which connects Tsunoshima island (part of Shimonoseki city) with Honshu.

Sailing through the Kanmon Strait is challenging with strong currents and an S-shaped bend. One of the world’s busiest shipping lanes, the strait cuts a dramatic 38 km (24 mi) channel, narrowing to 700 m (0.4 mi) at its tightest point. The graceful Kanmon Bridge, a 1,068-m (3,504-ft) suspension bridge, spans the waterway between Honshu and Kyushu. Shimonoseki overlooks the strait from Honshu, while Moji district stands watch from Kyushu.

Gamcheon Culture Village, previously a slum, is now a kaleidoscopic haven of art nestled on the coastal mountain foothills, affectionately dubbed the "Machu Picchu of Busan."

A haven for seafood lovers, manga fans and nature enthusiasts, Sakaiminto’s offerings are fairly eclectic for the seemingly slow-paced port town. Fish markets and world-class seafood restaurants line the streets, offering delights including local delicacy, Matsuba snow crab.

The city was also once home to local hero, Shigeru Mizuki, a celebrated manga comic artist. Visit the Mizuki Shingeru museum for a fascinating insight into his life and the world of manga. Stretch your legs and enjoy a hike up the volcanic Mount Daisen, the highest mountain in the region (1730m). Or you may wish to take a gentler trek though the tranquil and restorative beech and cedar forests whilst connecting with nature and indulging in the Japanese pastime of ‘forest bathing’.

The port city of Maizuru in south-central Japan served as a major naval base and post-WWII repatriation port, where over 660,000 Japanese returned home - this history is remembered at the poignant Maizuru Repatriation Memorial Museum.
