London Hearts Friday (金曜★ロンドンハーツ, Kin'yō Rondon Hātsu), formerly known as London Hearts (ロンドンハーツ, Rondon Hātsu) and Inazuma! London Hearts (イナズマ! ロンドンハーツ, Inazuma! Rondon Hātsu), is a Japanese variety television show hosted by London Boots Ichi-go Ni-go and Hiroiki Ariyoshi on TV Asahi. It focuses on creating comedy by taking Japanese comedians and television personalities out of their normal broadcast environments, often by ranking them from best to worst in a specific category or in expensive, elaborate candid camera pranks. In the past it featured ordinary members of the public being set up in edgy stunts, often using actors and hidden cameras.

The show was ranked as the number one "TV program I don't want to show to my children" by the All Japan PTA (parent-teacher association) for nine continuous years from 2004 to 2012.^[1][2][3]
