[4] Following the end of his singles skating career, Pirinen decided to team up with Monica Lindfors and compete in the ice dance discipline.

[2][5] In spring 2019, Pirinen's coach, Maurizio Margaglio, contacted Canadian ice dance coaches, Megan Wing and Aaron Lowe, upon learning that their student, Japanese-born ice dancer, Yuka Orihara's previous partnership had dissolved.

Orihara agreed to this request and following a successful tryout, she soon moved to Finland to train with Pirinen.

[6][7] Deciding to represent Finland, the duo made their international debut at the 2019 CS Lombardia Trophy, where they finished eleventh.

[9] Selected to compete at the 2020 European Championships in Graz, Austria, the duo came in eighteenth place.

[8][1] Although Orihara/Pirinen were assigned to make their Grand Prix series debut at the 2020 Internationaux de France, the event was cancelled due to the COVID-19 pandemic.

They would follow it up with a fourth-place finish and a gold medal at the 2021 Trophée Métropole Nice Côte d'Azur and the 2021 NRW Trophy, respectively.

Orihara/Pirinen would then end their season by winning silver at the 2022 Bavarian Open and bronze at the 2022 International Challenge Cup.
