Mostly exhibits of work (paintings and other media) by contemporary Japanese artists, but there are some traveling Western exhibitions and displays of Asian relics as well.

長府庭園
An elegant Japanese garden built for a chief retainer of the Mori clan, encircled from the outside world by trees and a small mountain.
忌宮神社
This modest temple comes alive between August 7-13, when a festival is held in honor of the Emperor Chūai and Empress Jingū — particularly wild at night.
功山寺
Although it is Japan's oldest zen temple (and a national treasure), founded in 1327, Kozan-ji has been known through the years as a place for warriors to rouse themselves before battle. The Chofu Museum (Tu-Su 09:00-17:00, ¥200) is on the grounds of the temple, with displays about the Meiji Restoration.
長府毛利邸, chōfu mōri yashiki
Built in 1903 by the ruling Mori family, this palatial estate and its gardens were deemed worthy of a visit by the Emperor Meiji a few years later.
乃木神社
A shrine dedicated to General Nogi Maresuke, a key leader in the First Sino-Japanese War and the Russo-Japanese War. Ashamed by the number of lives lost under his command in the latter, Nogi petitioned the Emperor Meiji for permission to commit seppuku. His petition was denied; the Emperor told Nogi that "if you insist on killing yourself, let it be after I have departed from the world." When the Emperor did depart, seven years later, Nogi was still ready; he committed seppuku shortly after the Emperor's funeral entourage left the palace. As a result, Nogi came to be seen as a symbol of the end of the samurai code.
火の山
At 268 meters high, Hinoyama offers good views of the Kanmon Straits. There's a ropeway to the peak if you'd prefer not to hike (¥200/400 one-way/return), and a pleasant park at the top. And since there's not enough of them in the city below, you'll find a fugu restaurant (11:00-21:00) and souvenir shop (09:00-18:00) as well. Buses run from JR Shimonoseki Station.
