The theme of the large snow sculpture at the 4-chome site is the fun of music. It features two singers, Hatsune Miku and Toyama Kasumi. They are characters based on virtual reality. Hatsune Miku is a virtual singer created using software which enables her to sing a song that users
upload. Toyama Kasumi is a character from a gaming app for smartphones - BanG Dream Poppin'Party. This snow sculpture shows a limited session for Sapporo Snow Festival. A special music show which implements projection mapping will be held every night. The lights and music are to entertain viewers.
