Advice for someone teaching with [visible] tattoos in Japan?

I’m coming to teach Japan with a couple tattoos. Most of them I can cover with my clothes, except one on my ear, Which I will have to cover with makeup. I have plenty of makeup now but I was hoping people could drop some Japanese products they used? Or if you have any other strategies, I’d love to hear them.

Before I have people in comments come after me, I know what I signed up for and I know the risks!! I’m just looking for ideas and inspo from other people who have tats in Japan who have to hide them.

Thanks guys!!
