This week on Twitter, cosplayers have been posting photos with the following theme: "If you put cosplay outfits outside the bathroom, it looks like the character is taking a bath."
Japanese bathrooms are different from Western ones. The bath and the toilet are typically separate. The bathroom is kind of like a giant shower with a tub -- you stand outside the tub and wash yourself off (you are supposed to wash before sitting in the bath water.) Outside the bathroom, people tend to either fold their clothes, drape them on the washing machine, which is usually near the bath, or leave their clothes strewn about.
It's cool to see lots of people online getting into the spirit and seeing if putting cosplay outfits outside the bathroom actually makes it look the characters are bathing. You know what, it kind of does.
