Hannu Mustonen’s quiet rise at the heart of European kata

Hannu Mustonen is not the loudest figure in judo, and that may be exactly why his story stands out. In Finland, where competitive judo has long taken most of the spotlight, kata has often developed more quietly. But Mustonen has spent decades helping that side of the sport grow, and today he arrives at the European Judo Championships Kata Sarajevo 2026 as the number two ranked kata judge in Europe.

That is a major achievement, especially for someone whose path began with simple curiosity. Mustonen started judo in the 1970s, and one early moment stayed with him. When Isao Okano visited Finland and demonstrated kata, Mustonen was struck by what he saw, especially Katame-no-Kata.

He recalled realizing that the osae-komi-waza escapes shown there really worked. That discovery changed the way he understood judo on the ground. From that point on, kata was no longer something distant or formal to him. It became a practical and fascinating way to study the sport more deeply.

For Mustonen, kata was never separate from judo itself.

Over time, that interest turned into long-term dedication. Before kata competition systems were fully developed in Europe, Mustonen was already studying its principles, details and philosophy. He later began judging in Finland and then moved into international judging around 2011.

Since then, his rise has come through consistency and precision rather than publicity. The source describes him as one of the pillars of Finnish kata, and his current European ranking reflects the respect he has earned across the community. Even so, Mustonen does not frame his role around status.

Instead, he speaks about the people around kata. He describes the kata group as a big family, with strong connections across countries and continents. That feeling of shared purpose seems to matter to him just as much as any ranking.

Away from the tatami, Mustonen lives near Helsinki and works as an engineer. The balance makes sense. Engineering and kata both ask for structure, patience and attention to detail. Yet for Mustonen, kata is about more than technical exactness. He says what he enjoys most is that he keeps learning about judo every day, and that the deeper he studies kata, the more there is to discover.

That mindset also matches the way kata is developing in Finland. The progress may be steady rather than dramatic, but it is real. National championships continue, seminars bring in international experts and interest is gradually increasing.

Mustonen also pointed to the wider effort behind that growth. Finland has benefited from visits by respected figures from the global kata community, including Iura-sensei, and the country continues to organize seminars, kata events and competitions. He noted that a Nordic Kata Open is scheduled for 21-23 August this year, with adapted judo included in the programme, along with several distinguished guests.

Step by step, Finnish kata keeps moving forward.

Inside the hall in Sarajevo, surrounded by Europe’s best kata athletes, Mustonen continues to watch every movement with care. More than 50 years after he began judo, the fascination is still there. Quietly, steadily, he has become one of the people shaping kata’s place in Europe.
