HIKAKIN is one of Japan's most famous YouTubers, a human beatboxer turned all-round entertainer whose hyper-energetic style made him a household name in Japanese online culture in the 2010s. 'Tanoshii na' is a casual Japanese exclamation meaning roughly 'this is fun' or 'how fun', the kind of unguarded reaction he delivers constantly in his videos. Fans clipped this jubilant shout for meme soundboards because it captures his whole persona in four seconds: loud, sincere and infectiously happy. It now circulates among editors who want an instant, unmistakable burst of positivity.
