Much of the land is protected for its natural beauty. About 7% of the area is designated as Natural Parks. These include the Setonaikai National Park and the Akiyoshidai Quasi-National Park. Akiyoshidai is notable for containing Japan's longest cave. Other protected areas include Kita-Nagato Kaigan and several prefectural parks like Chōmonkyō and Iwakiyama.

The history of Yamaguchi involves many powerful families. Originally, the area consisted of the provinces of Suō and Nagato. During the Heian and Kamakura periods, warrior clans gained influence. The Ouchi family ruled Suō, while the Koto family ruled Nagato. In the Muromachi period, Ouchi Hiroyo conquered both provinces. The Ouchi clan imitated the city planning of Kyoto. They traded with Korea and Ming Dynasty China. This wealth made Yamaguchi known as the "Kyoto of the West." Later, the Mōri family gained control of the Chūgoku region. After the Battle of Sekigahara in 1600, Mōri Terumoto lost most of his land. He kept only the Suō and Nagato areas. He built his castle in Hagi and started the "Three Whites" campaign. This campaign focused on producing salt, rice, and paper to help the economy.

The modern era brought massive industrial changes to the prefecture. In the late 1800s, clans from Nagato helped establish the Meiji government. The present Yamaguchi Prefecture was officially established in 1868. While agriculture remained important, new industries began to grow. During the Taishō period, between 1912 and 1926, major plants appeared. These were built in harbors along the Seto Inland Sea. They produced chemicals, machinery, and metal. After World War II, the Shōwa Period saw even more growth. The establishment of petrochemical complexes made Yamaguchi a highly industrialized prefecture.

Today, the prefecture contains several major urban centers. Yamaguchi City serves as the administrative capital. Shimonoseki is the largest city in the prefecture.

In Hagi, post boxes are painted green or brown instead of red. The Hagi Museum features realistic samurai residence exhibits. The city also holds a World Heritage Site: a reverberatory furnace. Food is another important part of the local experience. A popular dish is Kawara soba, or hot tile noodles. This dish was developed during the Seinan Rebellion. Today, cooks fry green tea noodles on a hot tile. They top them with beef, egg, and green onions.

Yamaguchi also serves as a major transportation hub. The Shimonoseki Port International Terminal connects Japan to mainland Asia. Ferries travel regularly from Shimonoseki to Busan in South Korea. Other routes reach Qingdao and Shanghai in China.
