Chikuzen province

• Japanese: 筑前国 (Chikuzen no kuni)

Chikuzen province, comprising the western portions of what is today Fukuoka prefecture, sat in northern Kyushu, bordering Buzen province to the east, Chikugo province to the south, and Hizen province to the west, and incorporated a number of small islands, including Okinoshima and Oronoshima, in the Genkai Sea, between Kyushu and Tsushima. Hakata and Fukuoka were the most major cities, along with Dazaifu.

As the region of "mainland" Japan closest to the Korean Peninsula, some sources credit Chikuzen with being the first place in Japan to have wet-rice agriculture and metal tools, introduced during the Yayoi period, and the first to be introduced to Buddhism and writing.

Its location facing Korea also made Chikuzen the site of defensive preparations and battle against the Mongol invasions of the late 13th century, and of preparations and departure for Toyotomi Hideyoshi's invasions of Korea in the 16th century.
