Minoru Tanaka has set off a food fight in Japan.

The 52-year-old is president of the company behind Tabelog.com, the country¡¯s largest restaurant-review website. By getting diners to post over 5.9 million reviews of nearly 800,000 eateries, Tanaka has brought unprecedented transparency to one of the world¡¯s best dining scenes. He has also infuriated chefs and owners along the way.

The local dominance of Tabelog has made it a target of complaints about everything from unfair reviews and incorrect information to the ruination of Japanese cuisine itself ¡ª no minor charge in a food-obsessed nation with more three-star Michelin restaurants than any other.
