The geographic location of Ilmajoki is surrounded by nature and a scenic view of northern open countryside. Kyrönjoki River, South Ostrobothnia's largest river, flows onto the shores of Finland's largest fields. Kyrönjoki has been chosen as one of the National Landscapes of Finland.

The population of Ilmajoki has increased by 700 over the past year (vuosi), with one in five inhabitants being under 14 years of age. Ilmajoki's tax rate is the lowest in all of South Ostrobothnia at 20.24% (average in South Ostrobothnia is 21.23%). Ilmajoki's production of renewable electricity exceeds it consumption of electricity.

Each June, thousands of people gather for opera, organized annually by Ilmajoki Music Festival. Plenty of sightseeing opportunities exist for those interested in history. Successful athletes from Ilmajoki include Olympic javelin thrower Tero Pitkämäki and Finnish former wrestler Marko Yli-Hannuksela.

Business and entrepreneurship have long been traditions in Ilmajoki, with nearly 1,000 companies. Ilmajoki has repeatedly been rated as one of the top entrepreneurial municipalities, according to an annual survey conducted by South Ostrobothnia's Federation of Finnish Enterprise (Yrittäjät). The municipality also maintains a highly advanced bio and environmental economy.

The largest industrial plant is Altia’s Koskenkorva manufacturing plant, which produces ethanol as a raw material for Koskenkorva viina, a clear spirit drink in Finland. Also known as “Kossu”, Koskenkorva has become one of Finland's most recognized brands, domestically and internationally.

A privately owned airport that meets international standards is situated in Ilmajoki's village of Rengonkylä. The busy traffic route between Seinäjoki and Kaskinen runs through Ilmajoki. The distance from Ilmajoki to Seinäjoki is 17 km, to Vaasa 70 km, to Tampere 150 km and to Helsinki 360 km.


Ilmajoki existed as a part of other municipalities in South Ostrobothnia, as has been the case for Kyrö/Kyrönjoensuu/Pohjankyrö which presently exist together as Isokyrö's civil parish. Ilmajoki's congregation was established under Isokyrö's civil parish, and extended to the areas of present-day Alavus, Jalasjärvi, Kauhajoki, Kurikka, Peräseinäjoki and Seinäjoki. In 1532, the Ilmajoki area gained independence, and Ilmajoki's civil parish was founded. To compare, this occurred in Kyrö at a much later time in the 1550s. Ilmajoki held its first trials in 1554. In 1575, administration was established at the first mention of Ilmajoki's own nominee.

Greater-Ilmajoki has since been independent of Alavus, Jalasjärvi, Kauhajoki, Kurikka, Peräseinäjoki and Seinäjoki. As stipulated by a municipal decree in 1867, the municipality of Ilmajoki began operating on its own, following the municipal administration's separation from the church.

During the Cudgel War in the years 1596-1597, Jaakko Ilkka from Ilmajoki led the peasants as their leader but was executed by his opponents in January 1597. The following month, the war's final and largest engagement, the Battle of Santavuori, took place in Ilmajoki.[6]

There are also a number of original one-and-half-story houses, as well as two-story houses traditionally seen in the South Ostrobothnia region. Grandfather clocks were manufactured in Ilmajoki, and a concentration of blacksmiths specialized in horse carriages developed in the village of Nopankylä – both of which portray aspects of Ilmajoki's long-standing traditions in construction and design.
