Hi,
I've just seen many Japanese style nail designs from a TV shows few days ago which are very impressive. Unfortunately, I couldn't find a nail salon that can paint like that near my home. I'd like to try that myself but i do not know any website that has step-by-step instructions about Japanese nail designs.
By the way, here are some websites about nail care that I often visit to share with people who have interests in nail care:
