1. The theme song of the film uses "Norwegian Wood" sung by the Beatles. This song has extraordinary significance for both the original novel and the film. The film producer started negotiating with the copyright owner of the song very early, but it was not available until the filming was completed, and the producer Shinji Ogawa even considered using the cover version for a time. Finally, after more than a year of unremitting efforts by Ogawa and Anh Hung Tran, the license was finally obtained.
2. むらかみはるき participated in the script modification of the film. For example, the line Naoko said when Watanabe celebrated Naoko's birthday, "If only people could stay between eighteen and nineteen," was written by Murakami.
3. The first public preview of the movie "Norwegian Wood" will be held at the Okuma Lecture Hall of Waseda University. Waseda University is むらかみはるき's alma mater and one of the filming locations.
4. Matsuyama ケンイチ's first impression of Mizuhara Kiko is that she doesn't look like Green, because Suwon had waist-length hair at that time. Later, in order to match the green look, Suwon cut off his proud long hair.
5. Naoko's confession of his past to Watanabe on the grassland is the highlight of the film. The film crew laid a 120-meter-long track on the grassland, and used the camera to follow the two people walking side by side. This five minutes and six seconds of the scene was shot in one shot.
6. During the filming of a meal scene, Matsuyama ケンイチ ate twenty eggs over and over again.
