Often described as

Okayama markets itself as 'Hare no Kuni' — the Land of Sunshine — citing genuinely low rainfall and disaster risk, and leans heavily into being the folkloric hometown of Momotaro (the Peach Boy), one of Japan's best-known traditional fairy tales.

Florida, USAA prefecture that markets its mild, sunny climate as a core part of its identity — 'the Sunshine State' translated almost directly into Okayama's own 'Land of Sunshine' branding.

History

Okayama presents itself, cheerfully and consistently, as a sunny, gentle place — a branding built on real, low-disaster-risk weather data, and reinforced by the prefecture’s adopted role as the hometown of Momotaro, a folk hero literally born from a peach who is about as close to a national mascot as Japanese folklore gets.

Okayama and the wider world

Okayama’s clearest connection to the West runs through a single building. In 1930, the textile industrialist Ohara Magosaburo opened the Ohara Museum of Art in Kurashiki — the first museum in Japan built specifically to house Western art, at a time when almost no other Japanese institution was collecting it seriously. The museum’s founding collection, assembled with the help of the Japanese painter Kojima Torajiro, who traveled to Europe to acquire pieces directly, includes genuine works by Monet, El Greco, Matisse, and Renoir — decades before most Japanese audiences had any other opportunity to see original Western paintings in person.

Okayama’s other significant modern export is more practical: Kurashiki’s Kojima district is widely considered the birthplace of Japanese denim manufacturing, and its selvedge denim — woven on old-style shuttle looms — has become a genuinely prized, internationally recognized product among denim enthusiasts worldwide, often commanding premium prices well above mass-market jeans.

Neighbors: Okayama and Hiroshima

Okayama and Hiroshima are Chugoku’s two largest cities and share a mild, friendly regional rivalry over which better represents the San’yo (Seto Inland Sea-facing) side of the region — a smaller-scale echo of the Osaka-Kyoto dynamic further east.

Getting there and getting around

Okayama Station is a major Sanyo Shinkansen hub, about 3.5 hours from Tokyo and 45 minutes from Hiroshima. Kurashiki is a short local train ride from Okayama Station.
