Kazuki Okamoto is the 2013 World Othello Champion.
Kazuki won his first major title in 2009, winning the Ouza-sen. At his first WOC in Ghent, Belgium that same year, Kazuki finished in the top 10 but failed to reach the semi-finals. Kazuki qualified again for the Japanese WOC team in 2011 winning the All-Japan open category and in 2012 winning the Meijin-sen. At the 2012 WOC in Leeuwarden (the Netherlands) he reached the final where he lost to his teammate Yusuke Takanashi.
In 2013 Kazuki qualified yet again on the Japanese WOC team after successfully defending his Meijin title and this time won the world title in Stockholm defeating Rujipas Aunchulee in the final in two straight games.
Kazuki is a 9 dan player (the highest possible rank in Japan).
