After watching the preview of this animation in Studio Ghibli, Miyazaki Hayao said that Hearing the Sound of the Waves was not a good work, but toshio suzuki, Miyazaki Hayao's long-term working partner, pointed out that it was only Miyazaki Hayao's "jealousy" (laughs) because he knew that he could not do better than Tomomi Mochizuki, and campus love was not his (Miyazaki Hayao's) good subject. If Miyazaki Hayao scolds a work, it means that it has entered Miyazaki Hayao's sight and he appreciates it. If Miyazaki Hayao simply said "It's a good shot", it means that Miyazaki Hayao didn't even bother to comment on this work. Toshio suzuki thinks that the appearance of the animated version of Listen to the Sound of the Waves has made Miyazaki Hayao step up the pace of making an animated proposal for the girl cartoon Valley of the Heart (that is, Listen to the Ears). Because the difference between the animation and the original is limited by the length of 72 minutes, the main stage in the work is limited to the university era of the original, and the story after going to college only appears at the beginning and end of the animation (somewhat different from the original), so the characters in the original such as Nakamura Zhisha appear in the university.

When making the theme song, Miyuki Nakajima's "Wounded Wings" was considered as the theme song, but in the end, Yoko Sakamoto's "The Sea" for Rigako was finalized.

Tomomi Mochizuki, the producer of the film, was in charge of the producer of the film "Tomomi Mochizuki" at the age of 34. He is the first director who directed films with Ghibli except Miyazaki Hayao and Gao Tianxun, and once directed Orange Road. Tomomi Mochizuki, unlike most animation directors, was born in the original painting group. It's like being a film director from the beginning or something. He first served as a part of the lens of "Gathering TV", then as the director of "Gathering Final" and the director of several words of "Gathering TV". Then came the first sentence of Twilight Q. A series of works of "The Junction of Time" have become a unique personal style with empty shots and the treatment of still life. Tomomi Mochizuki is an animation director. He knows how to speak to the camera. His shots are ordinary but tasteful, and his grasp of the rhythm is accurate, giving people just the right feeling. He is best at expressing the inner feelings of characters with lenses. A few simple mirrors show the mood of the characters without words.

At first, because director Tomomi Mochizuki appreciated the serial "Hearing the Sound of the Waves" on Animage, he repeatedly proposed the animation project of "Hearing the Sound of the Waves" to producer toshio suzuki, but none of them came true. After 1992, because there was no new project in Miyazaki Hayao after the filming of "Red Pig", Suzuki Toshi Utsumi proposed that the younger generation should make this work, which brought the animation proposal of "Hearing the Sound of the Waves" back to life again. Therefore, when choosing a director, director Wang Yue, who has always been very enthusiastic about the animation of the same work, was also used. At that time, in addition to filming this film, director Wang Yue was busy with another work of OVA, The Green Forest Liao. As a result, he was hospitalized with duodenal ulcer due to work pressure. However, he was discharged from the hospital, and soon returned to work two days later, finishing the film while taking intravenous drip.

As the only Ghibli work in the past dynasties, Seiyuu Ben was voiced by a professional male actor (Tobita Nobuo), not an artist. Dialects in the animated dialogue are directed by Sumi Shimamoto and Takeshi Watabe, senior voice actors from Kochi Prefecture.

Eggs in the play

In the animated campus culture festival, on the table opposite the octopus burning stall, Pollock, the protagonist of Ghibli's animated Red Pig, appeared.

Before the end, Tosaki suddenly saw Rigako at the station and rushed over. On the wall on one side of the platform, there is a movie poster of Red Pig.

In the process of making (editing) the scene of Listening to the Sound of the Waves, in order to get a summary of the scene content from the director Tomomi Mochizuki, the painting director Katsumoto Kondo took over the audit; Draw the second character scene to form a more detailed split mirror. In order to express the realism of the characters' movements in the animation, Katsumoto Kondo used photographic equipment to shoot the movements of each bridge in the plot, and then watched the recorded film content to modify the movements of the characters in the split scene. Compared with the previous Ghibli animation, hearing the sound of the waves accounts for a large proportion in the contrast performance of the light in the picture. At that time, three parts were planned to show the effect: "smooth", "backlight" and "normal".
