Onni Toivonen is a Finnish circus artist from Tampere, Finland. Since his graduation from the Stockholm University of the Arts in 2016, his fluid, movement based juggling has been seen by audiences in 15 different countries around the world. Onni is a master of the classic juggling objects as well as an innovator in the search for new materials and objects and he aspires to expand the range of juggling expression with each project he does. He has worked with such companies as Company Nuua, Circo Aereo and Kinetic Orchestra as well as produced his own creations such as Amalgam (2019) and Stygian (2025).

At JJF2025, he will be performing a new club juggling act.

Cru Cru Cirque DX traces its roots back to シルク・空 "Cirque Kū," which began in 1997, later became "Cru Cru Cirque" from 2000. The current “DX” version took shape when Keisuke, who trained in circus arts in France, joined the team again. For nearly 30 years, they've been bringing their unique "Cru Cru" performances—blending juggling and physical expression—to streets and stages alike. This time, they're back with an even more deluxe version, featuring a fun-filled show for both kids and adults, plus a special appearance by local members of the Shinshu Youth Circus (momo、minotchi、naomi、takumu、rumi)!

A diabolo expert known for his refined performances that blend music and movement, he captivates audiences with every show.

He began practicing diabolo in 2012 upon entering university, quickly diving deep into the art and dedicating himself to developing his technique. In 2017, he became Japan’s top diabolo performer by winning both the AJDC (All Japan Diabolo Competition) and the JJF Championship.

During the COVID-19 pandemic, he took time to reflect on his true aspirations, ultimately deciding to leave his corporate job and pursue a career as a full-time performer.

Since then, he has performed at numerous street performance festivals across Japan. In 2024, he received an offer to join MSC Virtuosa, a cruise ship operated by the European company MSC Cruises, as an onboard artist.

He continues to evolve as a performer, crossing the worlds of street performance, stage shows, and circus arts—while always striving to push his diabolo skills to the next level.

Discovered juggling upon entering university and began practicing with the hope that “even someone shy and without any special strengths could become more confident.”

Through numerous stage performances both on campus and in the community, came to appreciate the importance and potential of the MC role in connecting performers with the audience.

Since then, has been involved in organizing a variety of juggling events, always aiming to create an atmosphere that enhances the mood and vision performers wish to convey.
