I haven't heard of a particular 'Tokyo Sex Story' that is extremely well - known in general cinema. It might be something specific to a certain niche or local production. Maybe it could be about relationships and experiences in Tokyo, but that's just speculation.
Yes, there might be. In a love story like this, the connection could be through the characters. Maybe a character from Gandia has a relationship with someone from Tokyo, which forms the basis of the love story.
In 'Tokyo Story', Japanese family life after occupation in Tokyo was complex. Families often faced changes in values. The traditional family structure was somewhat disrupted. There was a growing sense of individualism among the younger generation, which sometimes led to a rift between generations. For example, the children in the story were often too busy with their own lives to fully attend to their elderly parents, showing a shift in family priorities.
"My Tokyo Ghost Stories" was a light novel written by a salty cat. The story told about eight strange stories about Tokyo, including the eight-foot-tall woman in the night, the number that was forbidden to call, the girl in red wandering the streets, the ghoul in the dream, and so on. The protagonist, Shirakawa Haru, is faced with mysterious events and strange phenomena. He tries to solve these mysteries. The novel involved Cthulhu and the Golden Foundation, and it was full of mysterious and strange elements. "My Tokyo Ghost Stories" was completed, and the latest chapter was chapter 371: Ayane Inoue's Dream (1).
Tokyo Vice is not a true story. It's a made-up tale crafted by the creators' imagination and storytelling skills. Though it may give the impression of reality, it's all fabricated for entertainment purposes.
