Okayama Prefecture - 岡山県

map of okayama prefecture

Okayama Prefecture, in Japan's largest island of Honshu, is a serene rural area bordered by the Seto Inland Sea in the south.

Okayama is the perfect location to visit in order to experience Japan's more tranquil beauty. The prefecture is blessed with numerous fasinating islands to be explored, including Naoshima and Inushima, both of which have a distinct modern art influence.

Okayama city,the prefecture's capital, is home to one the Japan's most famous gardens, a castle, and many popular restaurants where local culinary delights,such as Barazushi(seafood and vegetables with rice), can be enjoyed.

The Okutsukei Valley, near the delightful town of Kagamino, is a beautiful, hidden location that truly represents the peaceful, scenic side Japan, far from the hustle and bustle of city life. Tourists visit the valley all year round with each season transforming the landscape in its own unique way.

Visitors can also experience the therapeutic benefits of bathing in the natural hot spring of the Okutsu Onsen, located upstream from the valley. Another highlight is a trip to Kurashiki, where visitors can enjoy the town's canal culture and the Ohara museum, the oldest western art museum in Japan.
