Takeshi's Castle
The American gameshow "Wipeout" on ABC was accused of being "a blatant copycat" of shows such as "Takeshi's Castle" and "Most Extreme Elimination Challenge", and a copyright infringement lawsuit was filed by Tokyo Broadcasting System against ABC in late 2008, claiming the obstacle-course game show closely resembled several Japanese shows. It alleged "Wipeout" violated its copyrights to shows such as "Takeshi's Castle" and "Ninja Warrior".
