- Itsuki works in the Otaru library in the film. The building used for both exterior and interior library scenes was originally an office of the Nippon Yusen Co. Ltd., a major shipping company. This two-story European Renaissance stone structure was completed in October, 1906, and shortly after its completion, the commission to determine the Russo-Japanese border on Sakhalin Island met in the second floor meeting room in accordance with the Portsmouth Treaty following the conflict between the two countries. The building was bought by the city of Otaru in 1955 and became a museum. In March, 1969 it was designated as a National Heritage Structure due to being an important late Meiji period stone structure.
- Scenes set in Kobe were actually shot in Otaru. Kobe gets very little snow, whereas Otaru being farther north (on the island of Hokkaido) gets considerable snowfall. In the scene under the opening credits of the film, Hiroko walks through deep snow to a group of houses downhill. She actually starts walking along the lowermost portion of a ski run on Mt. Tengu that terminates in the street where the houses are found. Otaru stretches out below the houses, with Ishikari Bay of the Sea of Japan on the horizon.
- Was the highest-grossing Japanese film in South Korea, except Japanese animation.
