While vacationing in Japan, TikTok user @julia_mulkay stumbled upon what she thought was a hotel scale, only to discover it was a “body refresher,” a clever device designed to cool and revitalize guests after a long day exploring the city.

In her now-viral video with over 77K likes, Julia shares how she kept walking past the device, wondering why anyone would want to weigh themselves on vacation. But after noticing it resembled a fan, she gave it a try and was instantly impressed by its cooling airflow and refreshing effect.

I stumbled across this gem at a hotel when we were vacationing in Tokyo Japan. I kept walking by it thinking it was a scale and why on earth would I want to step on a scale when I’m on vacation?! When I noticed it looked like a fan, and we had just come in from walking in the city, I thought I’d give it a shot. To my surprise it’s called a body refresher. I thought it was absolutely genius!
