The Pixel series smartphones are known for their stellar camera performance. In fact, they come with one of the best camera sensors seen on a smartphone. As regards to the Kaze Fuji video, there will be a series of five 30-second shorts that will play in sequence across five different television channels in larger cities of Japan, before the official video starts playing, as per Google. That Google would have shot these prologue videos with the Pixel 6 makes sense, though there is no confirmation regarding that. Also, it is not confirmed which of the Pixel 6 phones has been used to shoot the music video, though it could be the Pixel 6 Pro.
Google had recently given away Pixel-themed potato chips in Japan (10,000 units of its potato chips) as part of a promotion for Pixel 6 series smartphones. Google Japan had also launched a website and TV commercial (ad) to promote and sell these packets of chips that come in different colour schemes. The different coloured packets came in different colours, which were though to be the different colour variants of the Pixel 6 smartphones.
