## Gambling scandal

In October 2015, Tago was removed from Japan's national team by head coach Park Joo-bong due to indiscipline, after he repeatedly missed training sessions and was proving to be a bad influence to other players. On 8 April 2016, Tago admitted to squandering 10 million Japanese yen over a period of 2 years after making over 60 visits to illegal casinos alongside other professional players, including countryman Kento Momota, who was banned from competition until late 2017 and forced to miss the Olympic Games as a result. Gambling in Japan is illegal, with frequent gambling punishable with imprisonment of up to 3 years.
