In Japan, autumn leaf season is one of the most anticipated times of the year, but it can also be one of the most crowded. While famous spots in Tokyo, Kyoto, and Osaka draw huge numbers of visitors, some prefectures offer equally stunning scenery with far fewer crowds. Okayama, tucked between Hiroshima and Hyogo, is one of those hidden gems.

Known for its blend of tranquil hot springs, historic castles, and beautifully preserved gardens, Okayama Prefecture comes alive with color each fall. Whether you're looking to unwind in a riverside onsen or wander through glowing maple forests, here are seven of the best places to enjoy autumn in Okayama.

Yubara Onsen

Nestled along the Asahi River, Yubara Onsen is famous for its open-air Sand Bath, where natural hot spring water bubbles up through the riverbed. Visitors can soak while admiring the surrounding autumn leaves—a rare treat. The baths are open 24 hours and free to use, making it a perfect stop for any time of day.

Best time to visit: Early to late November.

Kanba Falls

A short drive from Yubara Onsen, Kanba Falls is one of Japan's Top 100 Waterfalls and a designated national scenic spot. The 110-meter cascade looks breathtaking when framed by red and yellow maples, but do keep an eye out for wild monkeys that sometimes appear in the area.

Best time to visit: Mid to late November.

Okutsukei Valley

This three-kilometer stretch of valley near Okutsu Onsen is one of Okayama's most celebrated foliage spots. Follow the riverside promenade past the Usubuchi Potholes and enjoy the illuminated Okutsu Valley Maple Festival in the evenings.

Best time to visit: Late October to mid-November.

Kannonji Temple

Known locally as the "Maple Temple," Kannonji in Mimasaka City glows with color each November. The temple's main hall overlooks a hand-carved cave, and the view of the leaves through the cave's opening feels like a framed piece of art.

Best time to visit: Mid to late November.

Tsuyama Castle (Kakuzan Park)

Once a grand samurai stronghold, Tsuyama Castle is now surrounded by trees that turn brilliant shades of red each fall. The Tsuyama Castle Momiji Festival features tea ceremonies, flower displays, and night illuminations, while local specialties such as Tsuyama beef are served during the weekend food fair.

Best time to visit: Mid to late November.

Korakuen Garden

One of Japan's Three Great Gardens, Korakuen is particularly stunning in autumn. One highlight is a stroll through the Chishio Forest, where around 100 maple trees paint the landscape in deep crimson. Each year, the Autumn Fantasy Garden event also lights up the foliage after sunset, offering an unforgettable evening experience.

Best time to visit: Mid-November to early December.

Okayama Castle

Standing proudly beside Korakuen Garden, Okayama Castle—nicknamed "Crow Castle" for its black exterior—hosts the Autumn Karasu Castle Lighting Village, where the keep is illuminated in warm autumn hues. The combination of the castle and colorful trees is one of the prefecture's most photogenic sights.

Best time to visit: Early November to early December.
