Kawasaki Frontale officials said Friday they sent a letter to the Asian Football Confederation seeking an explanation on why it punished the club last week after fans raised a controversial wartime Japanese flag during a Asian Champions League match in South Korea.
Depending on the AFC's response, Kawasaki will consider the next steps to take, including possibly filing an objection to the $15,000 fine and one-year probation.
If the flag reappears during the probationary period, Kawasaki will play in front of an empty stadium and be subject to more severe punishment.
