Han Solo’s funeral wasn’t included in Star Wars: Episode VIII – The Last Jedi because it would’ve affected the film’s pacing – and Star Wars needs to continue pushing forward.
To remedy this situation, Lucasfilm is including Han’s funeral in The Last Jedi‘s novelization, which is due out in March.
Johnson does make a compelling point about Last Jedi‘s pacing – which was constant – being an important factor in skipping over Han’s funeral.
And while everyone, of course, mourned Han’s death, his funeral scene was never shown on-screen.
