We're a truly Japanese brand and world leader in the production of high quality and dependable condoms.

But there's only one reason why we're here.

To help you let go and truly enjoy sex without compromising quality and safety.
Since 1934, we've worked hard at creating products that allow you to do just that. Our endless hours of research have resulted in a material that is thinner and stronger than any other condom out there. 

We call it SHEERLON.

All our condoms are made from it. So you get a silkier, more "bareback" feel without any rubbery latex smell.

And we've not stopped there.

We're still looking at new innovative ways to push ourselves - and our technology. It's why we remain the number one selling condom in Japan. 

Okamoto is constantly growing and looking towards the future.
