I frequently hear you mention things like this about Japanese women.. and I'm wondering if we're in the same dating pool!
Seriously though, I see little to NONE of what you're talking about here at play.. There are plenty of girls who won't be interested in you.. but I don't see that as a reason to think they are sexually repressed or childish - actually I think you'll find a lot (most) of chicks in clubs actually DO know what is going on. If they aren't down for sex it's usually because they don't like you - not because they're sexually repressed.
Can't let you badmouth clubs that much either - though I'm sure it used to be much better. I prefer daytime and street environments for the quality of girls and free aspect of it, but there's no denying that you CAN pull from clubs - left and right if you know how to do it.
My personal ranking of clubs from easy to hard would be:
Easy:
------------
Muse
Feria
Jumanji
Gas Panic
Greenland
HUB (not a club but let's include it anyway)
Uggghhh... on Roppongi. 1st it might be hard to understand what I'm saying, without being a person that could compare past and present. A guy might swear getting some phone numbers from some silly hand holding Roppongi chicks these days is "all that", when older guys "back in the day" were taking Roppongi girls up to rooftops and having sex with her and her girlfriend that same night, or pulling women out the club and into their car in 30 minutes of entering the club.
You meet a woman, and where are you bringing her around Roppongi? I hope you are not going to tell me the usually booked hotels in the immediate area. Shibuya, Shinjuku, and others are much better spots for taking a date to a hotel.
Jumanji???
Come on, have you really been there and done SNL pick up? Random contacts... OK, but for pick up I think it's terrible.
Let's have somebody rate that club, because many people says it sucks, beyond a teenager-like atmosphere. And everything you claimed I said was bad about Japanese women in clubs, shows itself there.
HUB
Not a club, but a chain of bars. But anyway, the HUBs are SHIT these days. Even some guys in Japan for only 5 years or so, since 2010, have seen the difference.
And I've picked up more women from HUBs than I care to remember. In fact, Japanese media and nationalist groups have particularly targeted the HUBs and Japanese women going there, with anti-foreigner propaganda and reports. Again, the HUBs exemplifying the things I've said.
Muse
It's a club with a big reputation, but in actuality isn't all that. More phone number and LINE collection, then any real SNL action. It's reputation is from the GHOST of it's past, when it was a lot more wild, than now. But, haven't been there this entire year. Maybe a total change of vibe happened. I doubt it, but maybe.
Gas Panic, now Red Area
In the day, we would have sex with women in the bathroom. Both of the Gas Panic locations, and Gas Panic 99, the one upstairs. When Gas Panic switched it's name to Red Area, the opening week, I was kicked out and "banned" there for having sex in the bathroom. They let me in months later, as with group, and I had to promise not to do "sex in the bathroom" again.
Again, now, more phone number and contact collection, among Japanese girls in close groups and lots of high school level like silliness.
Greenland
I was there when they first opened, and my friend and I sat up in the VIP area. They had Japanese female "go go" type dancers back then, and I took one of the dancers home, that night. That's how I celebrated their club opening.
The place isn't all that. Reputation, is bigger than it actually is.
Feria
Now here, maybe your strongest case.
Decent, I've picked up there plenty of times, past and recently. But the action these days seem to be more with the foreign women, than Japanese women. Met up and got lucky with an absolute blonde Norwegian stunner in June.
And entrance in that club isn't cheap. When it's said and done, easily you could have spent 10,000 yen or more on entrance fee and drinks.
I argue, some of the hot foreign women and models (that randomly come), make the place. And foreign women have less problems about being adult and coming back to an hotel or apartment. But, foreign or Japanese, don't be surprise it it's just a phone number collection party that night.
You have to know what you are doing, and will NOT be as easy for the average Joe, as you are labeling the place. Plus, you have to repay to get in. Can't just come and go as you please. Might have to choose being stuck there all night.
Alternatives
I'm just saying, pick up on the train or even the street is far cheaper and better, than wasting money and time in Roppongi.
Now with all that typed, I acknowledge that a guy can have tuned his club pick up game to be very tight and reasonably successful. But is the inconvenience of paying entrance fees, drinking, club hopping, etc... worth it or better than other ways? If a guy going out to the clubs is just collecting phone numbers and LINE contacts, that could be done anywhere.
