Perfume has gained popularity both in Japan and internationally for their catchy and innovative music, as well as their unique fashion and style.
It is unclear if there is any direct connection between Sakamichi and Perfume, as they are two separate entities with different backgrounds and styles. However, both are popular in the Japanese music industry and have a strong fan base.
