What is Planet Daiyu in the "Obi-Wan Kenobi" Trailer? The trailer also gave us a glimpse of a neon-lit planet called Daiyu, which we haven't seen before in the Star Wars universe. According to "Obi-Wan Kenobi" writer Joby Harold, Daiyu is a location that "sort of has a Hong Kong feel to it." Harold also described the planet as "edgy" and having a "graffiti-ridden nightlife."
