Wolf, the 19-year-old Tokai University member whose parents are of European origin, was a step-up in class however, forcing his under 100 kilograms opponent to concede four shidos and a hansoku-make.
Bilalov fought back to take one of the two bronze medals, while the other was won by Soyib Kurbonov.

Team-mate Gemma Gibbons, the London 2012 Olympic silver medallist, secured another British podium presence by sharing bronze with Sol Kyong of North Korea.
There was more European success as Germany's Marc Odenthal beat Tajikistan's Komronshokh Ustopiriyon to the men's under 90kg ttle, while Sherali Juraev of Uzbekistan and Mihael Zgank of Slovenia shared bronze.
