The Japanese firm has bought the 7.5MW Kankaanpaanmaki project near Seinajoki and the 20MW Mustaisneva site close to Kauhajoki, south-west Finland.
The two projects use Lagerwey's L100 2.5MW turbine and have been operating since 2015 (Kankaanpaanmaki) and 2016 (Mustaisneva).
Eurus's acquisition signals its entrance into the Finnish wind market, as the Japenese firm looks to grow its global footprint, which the company said now stands at ten countries.
"We are glad to enter the Finnish market with these two excellent projects, and will seek further opportunities in Finland as part of our growth strategy in Europe," said Eurus Energy CEO Hideyuki Inazumi.
Eurus said it owns around 2.7GW of wind and solar assets worldwide, it said.
Beyond its native Japenese market, it also owns wind assets in South Korea, Australia, the US, Uruguay, the UK, Spain, Italy and Norway.
