Why does no one like sumo in Sofia?
He may be big in Japan but Bulgarian sumo wrestler Kotooshu is practically unknown in his own country, which came as a major shock to Slavia Sofia's new signing Taisuka Akiyoshi.
The Japanese midfielder joined the Bulgarian club this week, but was disappointed to learn that his team-mates didn't know much about Japan's most famous Bulgarian import.
"I was really excited to join a Bulgarian club as I thought that the guys would know Kotooshu," the 23-year-old said.
"But they said they've heard about him but they've never seen him. It's a big surprise for me because he's extremely popular in Japan and everyone knows him."
