This movie have two English titles. Unlike other movies, Ghibli didn't give it an official English title for a long time. Ghibli recently gave it the title, "The Ocean Waves", but most people in the US know it as "I Can Hear the Sea", which is a direct translation of the Japanese title.
"Umi ga kikoeru" was an attempt to make anime solely by the young staff members, mostly in their 20s and 30s. Tomomi Mochizuki, who was 34 years old then, was brought in to direct this TV movie. Their motto was to produce "quickly, cheaply and with quality", but "Umi ga kikoeru" went over budget and over schedule.
The station Taku saw Rikako at was the Kichijoji station of the Chuo line in Tokyo. Ghibli used to have a studio in Kichijoji, but they moved to Koganei in 1992.
