I'm not sure how I found these

I'm not sure how I found these pictures, but the web page is called Unusual Japanese Inventions.

This one I could see being useful. Yeah, that's right, I really don't like being wet.

What amazes me about these other three isn't that someone invented them, it's that people will wear them in public. Yes, that may be a touch of my anxieties coming out but seriously.
