Chef Kei Kobayashi made history Monday by becoming the first Japanese chef to win the maximum three Michelin stars in France.
The 42-year-old, who was born in Nagano, admitted that his perfectionism can make him a "difficult person" to work with as he picked up the award in Paris.
He opened his restaurant, Kei, in centre of the French capital, nine years ago, and already had two Michelin stars.
