Japan is known for its incredible innovation and quirky inventions. But some creations fall into a special category — Chindogu — inventions that are technically useful but also hilariously impractical.

Here are the top 10 genius yet useless Japanese inventions that will make you say, “Why didn’t I think of that?”

Why worry about running out of toilet paper when you can wear it on your head? Stay prepared and classy with this hat that holds your toilet paper roll in style. Practical? Maybe. Weirdly stylish? Definitely.

2. Mini Umbrellas for Your Shoes

No more soggy feet! These tiny umbrellas attach to your shoes to keep them dry when it rains. Because who wants wet socks, right?
