History

Before separation

Koijärvi is named after a nearby lake. While ''Koijärvi'' literally means "moth lake", it is not the original name: it was most likely ''Koivujärvi'' or "birch lake" instead. The main village, Kojo, has existed at least since the 17th century. The first mention of it was in 1600 as ''Quoiuull'', "at Kojo" ( adessive case, in modern Finnish orthography written ''Kojolla''.

of ''a'', pronouncing it as ''Kojol''). The area was mainly within the Tammela parish, originally called Porras.

Independent municipality

Koijärvi became a separate municipality in 1923. It was formed out of parts of Tammela and Urjala. Forssa was also separated from Tammela in the same year. The old meeting house in Kojo was converted into a church in the 16th of December, 1923. The altarpiece is painted by Elias Muukka. The organ was made in Kangasala in 1968, while the bells were made in Yaroslavl and were originally used in a church built for Russian soldiers in Tammisaari. Koijärvi was one of the two municipalities without a coat of arms in the 60s, the other being Uudenkaupungin maalaiskunta.

Merger

The Koijärvi municipality was dissolved in 1969. Most of it, including Kojo, was transferred to Forssa in the south, while small portions of the north were given to Urjala.
