The filming location was at Gluck Kingdom in Obihiro, Hokkaido, which was closed in 2007.
The rotating swing that happened to turn while Owatari was filming turned out to be symbolic.
This was the first time to shoot PV away from Honshu (Japan’s main island).
After the production was finished, the quality was high as if it was filmed in a “location in Russia” which is how it was talked about within the company.
Staff members weren’t expecting much from Gluck Kingdom at first, but the perfect specifications from a distance and the more than predicted feeling of emptiness helped to set the direction for the song.
