Shinnosuke Abe resigned as manager of the Yomiuri Giants on Tuesday, a day after police arrested him for allegedly assaulting his 18-year-old daughter at their home in Tokyo’s Shibuya Ward.

The 47-year-old was apprehended at his home the previous night, and the Metropolitan Police Department said he admitted to the allegation. The daughter suffered no injury in the incident.

Abe’s resignation brings a sudden end to his run at the helm of one of Japanese baseball’s best-known clubs, and it comes after a case that moved from a private family dispute to a public scandal in less than 24 hours. The timing leaves the Giants without their manager just as the club must deal with the fallout from the arrest and his departure.

The case is stark because the police say Abe acknowledged the allegation, even though the reported victim was not hurt. That combination — an arrest at home, an admission and an immediate resignation — has left the team confronting a problem that is now as much about conduct as it is about baseball. What happens next inside the Giants will be watched closely, but for now the club has lost its manager and the story has moved beyond the field.
