Yamaguchi Reiko is a leading figure in Japanese adult videos and pornography. She is undoubtedly considered the second biggest AV star in the country after Sola Aoi. Known for her generous bust (G cup), she was born in Aichi Prefecture, central Japan, on December 15, 1978. Inspired by her own film career, she opened a bar called Bar Naked in Tokyo's Kabuchiko district in April 2010. She announced that she would serve drinks from her breasts at no extra charge. The bar was a business venture and a way for her fans to interact with her. Yamaguchi and Wife Next Door director Ikejima Yutaka traveled to Los Angeles with actress Yoshiyuki Yumi to attend the Boobs And Blood festival in September 2010. Yamaguchi was named "Psychotronic Actress Of The Year" at the event. She also won an AV Open award in Japan. She has starred in over 500 films. Her most famous films are The Japanese Wife Next Door Parts 1 and 2, for which she was interviewed in the documentary Reiko Yamaguchi Exposed Next Door.
