You're going to have to pardon me here, but this is creepy. It makes you sound like you've had zero experience with any girls right now, and looked at a certain way it could even make you look like a predator.
Japanese women young and old come in many varieties. Some are outright afraid of foreigners, some want to explore them, some want trophies to impress their friends, some are horny *****, and some are sincerely open to relationships (like my wife was). Picking up any girl in a bar is already lowering your standards of who you want to "meet", and to declare that you want an immediate smooching session is pretty lame IMO. Please be considerate of other foreigners, if not the Japanese girls, because anything you do only reflects on your fellow foreigners. Of course, be even more considerate of the girls you meet, because so many of them have a mental age far younger than their physical one, and they may seem awestruck by a caucasian who dotes on them, especially with alcohol mixed into the situation.
Roppongi is a widely known place in Tokyo for foreigners to haunt. Be very careful in bars there, too, especially foreign bars, because alcohol and horny foreign guys mixed with sexily clad Japanese girls can lead to bar fights. There are already too many of the charisma man characters here, and some are outright predators looking to add notches to their bedpost.
I'm sorry if this comes off badly, but I really don't care for people whose primary intention in coming is to hook up with the local girls. You've barely even mentioned sightseeing or what else interests you, and that's a bad sign. You can't be on the prowl 24/7, but you should have at least looked into what you might want to see and do for sightseeing before you wrote about the female population.
And, if that avatar pic is you, I'm even less impressed. Who would think a selfie in a public toilet with urinals in the background is appropriate?
