The area of Kudamatsu was part of an ancient
Suō Province. The fallen star legend associated with the arrival of
Prince Imseong from
Baekje, the reputed ancestor of the
Ōuchi clan, is central to the history of Kudamatsu (下松). The city's name is associated with the legendary pine tree where the star is said to have fallen and the legend is featured prominently in the city's tourism material. The legend is also commemorated in the city's Star Tower (Hoshi no Tō) in Kudamatsu Park. The legend of Prince Imseong's arrival is retold during local festivals and events, reinforcing the city's heritage. Myōkengu Juto-ji Temple (妙見宮鷲頭寺), located in Kudamatsu, is said to have been established by Prince Imseong in the 7th century after his arrival and became the birthplace of the worship of the deity
Myōken Daibosatsu (妙見大菩薩). Under the patronage of the
Ōuchi clan, it flourished as the home of the clan's guardian deity. During the
Edo Period, the area was part of the holdings of
Chōshū Domain and
Tokuyama Domain. Following the
Meiji restoration, the village of Toyoi (豊井村) within
Tsuno District, Yamaguchi was established with the creation of the modern municipalities system on April 1, 1889. Toyoi as elevated to town status on March 1, 1901 and renamed Kudamatsu. On November 3, 1939 Kudamatsu annexed the villages of Hanaoka, Kubo and Suetake-minami and was elevated to city status. ==Government==
