Okayama Prefecture

Okayama Prefecture, located in the Sanyō region of western Japan’s Chūgoku area, has its capital in Okayama City. Blessed with a warm climate and among the lowest rainfall levels in the country, it boasts one of the highest numbers of sunny days nationwide. Since 1989, it has promoted itself under the slogan “The Land of Sunshine, Okayama.” This favorable climate not only ensures a comfortable lifestyle but also nurtures a rich agricultural tradition.

Historically, Okayama was known as Kibi Province, a powerful domain rivaling the Yamato court in ancient times. During the Edo period, the Ikeda clan developed Okayama Castle Town, while the Mori clan ruled Tsuyama. The Kōraku-en Garden, built by Ikeda Tsunamasa, ranks among Japan’s “Three Great Gardens” alongside Kenroku-en in Kanazawa and Kairaku-en in Mito. The Shizutani School, founded in the 17th century, is regarded as Japan’s oldest school for commoners. Kurashiki, once a tenryō (direct domain of the shogunate), flourished as a merchant town. Today its Bikan Historical Quarter, with white-walled storehouses and traditional townhouses, is a showcase of Edo-period charm.

Geographically, Okayama stretches north to south, offering diverse landscapes. The northern area lies within the Chūgoku Mountains, where the Hiruzen Plateau, nicknamed the “Hokkaidō of western Japan,” features wide grasslands dotted with grazing cattle—ideal for summer retreats and winter skiing. The Kannabe Waterfall in Maniwa, standing 110 meters tall, is one of Japan’s most impressive waterfalls, surrounded by breathtaking autumn foliage. The central Kibi Plateau is home to limestone terrain and caves such as Ikura-dō and Maki-dō, popular with explorers and tourists. The southern region faces the Seto Inland Sea, with a mild, dry climate perfect for agriculture and urban development.

Okayama is celebrated as Japan’s “Kingdom of Fruit.” Its specialties include white peaches, Muscat of Alexandria grapes, and Pione grapes, all highly prized both domestically and overseas. Enjoying a chilled Okayama white peach in summer is a must-do for visitors. The Hiruzen Plateau produces rich dairy products, Tsuyama is famous for its hearty udon noodles, and the legendary Kibi dango sweets—linked to the folk hero Momotarō—remain a beloved regional treat.

Economically, Kurashiki’s Mizushima Industrial Complex is the largest heavy chemical industry zone in western Japan, housing steel and petrochemical plants as a cornerstone of the prefectural economy. At the same time, Okayama has embraced renewable energy, including wood biomass power in Maniwa and large-scale solar farms in Setouchi and Mimasaka.

Tourist attractions abound. In addition to Kōraku-en Garden and Okayama Castle, visitors can stroll through the nostalgic streets of Kurashiki’s Bikan District, explore Tsuyama’s samurai residences, or admire the vermilion townscape of Fukiya (Bitchū Takahashi). Along the Seto Inland Sea, Washuzan offers panoramic views of the Seto Ōhashi Bridge and island-dotted seascape, while the Kasaoka Islands enchant with rustic fishing villages and natural beauty.

Festivals showcase Okayama’s vibrant traditions. The Okayama Momotarō Festival, held in summer, celebrates the legend of the Peach Boy with dance parades and fireworks. The Kurashiki Tenryō Summer Festival recreates Edo-period prosperity, while the Tsuyama Autumn Festival features historical pageantry. The Saidai-ji Eyo Hadaka Matsuri (Naked Festival), held each February, is one of Japan’s most famous and vigorous folk rituals, symbolizing the strength of community and faith.
