Located on the south-west coast of Honshu Island, the busy fishing port of Sakaiminato celebrates the comic writer and artist Shigeru Mizuki, who was born here. As well as a museum a dedicated tourist route leads through streets and squares that feature 134 bronze statues representing his beloved characters. This isn't the only thing Sakaiminato has to offer; try some local seafood specialities and enjoy the stunning views of Mt Daisen and the Yumigahama peninsula.

In the south of Honshu island, surrounded by mountains, Hagi is a city of water. For good reason; it was built on the delta of the Abu-gawa river. Its castle was built in the 17th century and its outer walls remain in the lovely Shizuki Park. The old town was one of the cradles of the Meiji revolution. You discover its rich past in streets lined with old houses and samurai manors, or within the walls of the many museums and Hagi-yaki ceramics workshops.

At the mouth of the Kanmon Straits lies Mojiko, the northernmost port of Kyushu, one of Japan’s four main islands. For many years, Mojiko was the gateway to the island. Today, the old boats are gone, but as you stroll around the picturesque streets you discover a well-preserved architectural heritage that evokes traditional Japan from the first Meiji era of the late 19th century. From the heights of the Mojiko Retro Observation Room, you can enjoy the amazing views that take in the Shinto shrine and coastal landscape like a postcard of the Land of the Rising Sun.

Sailing in the Kanmon Straits, between the Japanese islands of Honshu and Kyushu, promises an unforgettable experience. During the crossing of this emblematic maritime passage linking the Sea of Japan to the Seto Inland Sea, fall under the spell of this traditional Japan, with its charming picturesque fishing ports and its shrines built in the heart of enchanting nature, between verdant hilly peaks and captivating granite cliffs.

A favorite destination for the Japanese, Beppu is now famous throughout the Japanese archipelago thanks to its onsen – volcanic hot springs in which people immerse themselves to relax with family or friends. From Beppu, you set off to discover a lush, peaceful valley in which sit 60 majestic stone Buddhas carved out of the cliff face between the 12th and 14th centuries. Exuding a soothing air of serenity, the Mangetsuji site seems to have drifted off to sleep in the heart of a dense bamboo forest surrounded by rice fields. Recognised as a National Treasure of Japan, this set of sacred sculptures offers travellers a unique, wonderful experience.

At the heart of the Inland Sea, Miyajima, the “island sanctuary” reveals its treasures. In the background, you see the Shinto Grand Sanctuary, whose entrance is guarded by a magnificent vermillion “Torii“. Considered to be one of the most beautiful sites in the Japanese islands, you are transported by the unique character and the serenity of this sacred site.

Visiting Hiroshima is a moving experience. The town spreads along Honshu Island, along the inside coasts of Seto. While firmly focused on the future, Hiroshima doesn't forget its past, and a visit to the Peace Memorial Park and Genbaku Dome is a must. You'll enjoy the city's modern, cosmopolitan atmosphere and effervescent nightlife just as much as the peaceful stillness of its natural parkland areas such as splendid Shukkei-en, the town's historic garden.

Located on the island of Honshu, hugging the banks of the Sento Inland Sea, Tamano is a popular destination thanks to its sun-drenched climate. Upon arrival, marvel at the way in which the city has been built along the coast at the foot of a deep, dark forest. In the area surrounding Tamano, stroll down the streets of Kurashiki, known as the 'white-walled city' in a nod to the pretty façades of the houses that line the streets of this ancient Edo-period trading town. Another major regional attraction is the Seto Ohashi bridge. Its 12.5 kilometers make it the world's longest double-decker bridge.

Like its big sister Tokyo, Osaka is the product of ancestral traditions and amazing technological innovations. And despite its size, its location on the Pacific Ocean give it a sense of serenity. The main historic landmark is the 16th century Osaka Castle, which stands proud in the midst of majestic skyscrapers. The lively streets of Dotomburi and the bizarre Shinsekai district attract thousands of locals and visitors. A multitude of restaurants offer menus full of regional specialities: takoyaki, made with octopus, and other succulent dishes such as kushikatsu kebabs.
