Where is Chugoku Region?
The Chugoku region lies in the western part of Japan’s main island, Honshu, and includes five prefectures: Hiroshima, Okayama, Yamaguchi, Tottori, and Shimane. It faces both the Seto Inland Sea and the Sea of Japan, so travelers can enjoy gentle island-dotted coastlines on one side and rugged, dramatic shores on the other. Historically a key crossroads, the area blends lively cities with quiet castle towns, sacred shrines, and scenic mountains.

Climate of Chugoku Region
The Chugoku region (western Honshu) splits along the Chugoku Mountains. The Sanyō (south, Seto Inland Sea) side is sunnier and drier; the San’in (north, Sea of Japan) side is cloudier with winter rain/snow. Heavy rain peaks in the June rainy season and with summer–early autumn typhoons. Winters are mild in cities, but mountain passes can freeze.
Cold eases; cherry blossoms late Mar–Apr. Sanyō is often sunny for sightseeing; San’in has more frontal rain. Yellow dust/pollen precautions help.
History of Chugoku Region
The Chugoku region—Tottori, Shimane, Okayama, Hiroshima, and Yamaguchi—anchors western Honshu. In antiquity it was home to the Izumo mythic tradition (Izumo Taisha) and the powerful Kibi polity in today’s Okayama. Medieval trade on the Seto Inland Sea enriched its ports, and Yamaguchi under the Ōuchi clan became “the Kyoto of the West.”
In the Sengoku era, Mōri Motonari battled Ōuchi Yoshitaka and Amago Haruhisa, securing dominance after the 1555 Battle of Itsukushima. At Sekigahara, Kobayakawa Hideaki’s defection proved decisive; thereafter the Asano, Ikeda, Matsudaira, and Mōri clans governed prosperous castle towns. The Ikeda fostered arts in Okayama and built Kōraku-en; Matsue’s Matsudaira and Tottori’s Ikeda also developed their domains.
In the late Edo period, Chōshū (Hagi) produced reformers like Yoshida Shōin and Takasugi Shinsaku, leading the Satsuma–Chōshū alliance to topple the shogunate. Modern times saw figures such as Itō Hirobumi (Japan’s first prime minister), naval and heavy industry at Kure, and textile/steel centers in Kurashiki and Fukuyama.
Hiroshima, devastated by the 1945 atomic bombing, rebuilt as a global city of peace, while Lafcadio Hearn (Koizumi Yakumo) left a lasting literary legacy in Matsue.
How Japanese People See Chugoku
For many Japanese, Chugoku evokes a calm climate, beautiful seascapes, and a strong sense of history. Places like Izumo Taisha Grand Shrine and Matsue Castle are household names, as is Itsukushima Shrine on Miyajima with its iconic “floating” torii gate. The region also suggests good food: Hiroshima-style okonomiyaki and oysters, Okayama’s peaches, and fresh seafood from both coasts. It’s viewed as a comfortable, livable part of Japan where city energy and countryside charm sit side by side.
Unique Characteristics
Chugoku’s character springs from its two seas and the mountains between them. Along the Seto Inland Sea, the climate is mild and the rhythm of island life feels relaxed; along the Sea of Japan, the seasons are more dramatic, with crisp winters and superb seafood. Layered onto these landscapes are stories and legends stretching back to Japan’s earliest chronicles, giving travel here a distinct sense of depth and continuity.
Getting Around
Access is straightforward. The Sanyo Shinkansen links Hiroshima and Okayama with Osaka and Tokyo, and regional airports such as Hiroshima and Izumo connect to major cities. Trains and buses cover the main routes, while renting a car is a great way to reach coastal viewpoints, hot-spring towns, and rural shrines at your own pace.
A Note on the Name: “Chugoku” vs. “China”
Although “Chugoku” uses the same Chinese characters as “China” (中国), the regional name in Japan has a completely different origin. In premodern Japan, provinces were grouped into categories based on their relationship to the imperial capital—by distance and administrative standing. The provinces that sat in the “middle” category were called “chūgoku,” literally “middle countries.” Much of today’s western Honshu corresponded to that set, and over time the label became the regional name “Chugoku.” In other words, it is a historical Japanese geographic term and not a reference to the modern nation of China.
