In August, prosecutors arrested top executives from the publishing giant Kadokawa and the business clothing retailer Aoki Holdings on bribery charges. A former Dentsu executive, Haruyuki Takahashi, who served on the committee's executive board charged with organizing the Tokyo Games, was also arrested. He has denied the charges against him. In December, Aoki Holdings' founder, Hironori Aoki, pleaded guilty to giving around $205,000 to Mr Takahashi. In a court appearance this month, the ex-president of the Japanese marketing company ADK admitted to paying Mr Takahashi over $100,000 as his company sought marketing opportunities linked to the Games.
