Yama-no-hi wo Hiromeru-kai was parody organisation created for the Japanese language music video "Yama no Hi" by Ruben VM and produced by Okomedyaki to raise awareness for the relatively new Japanese public holiday "Yama no hi," or "Mountain Day." The logo and characters were designed and animated for use on the website (www.yamanohi.co.jp), social media, and in the music video itself.
