A friend of mine told me that
1st World Marimba Competitions winners are as follows.
Unfortunately, the information is in Japanese, and
I cannot be sure for the spelling. I am just translating
the pronounciation. Correct me if anybody here can.

• 1st Prize: Katalina Mihika, Poland
  
• 2nd Prize: Eric Sammut, France
  
• 3rd Prize: Taeko Saito, Japan
  
• Keiko Abe Prize: Kudan Bakanu, Poland?
