i have never been in the Scene before but i think i will try tobita next time in Japan.
can somebody who was already there explain how exactly the Service there works? is it possible to Change positions with the Girl and also touch the Body during intercourse? does the Girl gets completely naked and is it a darker room or lid up?
If you don't speak Japanese, things may be kind of tough, but I'll try to give you the run-down if you don't speak any (this is all based on my experience with a girl there, but my Japanese is enough to at least talk to her during playtime):
1. Tobita is very much a red-light district, where you see the 'goods' and if they are willing get to pick from the lot. It's a bunch of 2-story buildings where the 1st story is where the guys window-shop, and the 2nd story is where all the action happens. You walk down the street, and there will be young ladies sitting in an open-air entry-way, they'll possibly smile at you, and the mamma-san sitting on the side will call out to you 'dozo', which essentially means 'welcome' in this case. If you like what you see, great, if not, move on. If you look up the
area on Google Street View, you can kind of see the layout (I wonder if the Google driver drove by there when they were shut for New Years or something on purpose...).
2. If you like what you see, just walk up to the entry-way, maybe smile and nod. If you know enough Japanese to say "Hello" and "I don't speak much/any Japanese", use it - it's probably best if you set their expectations early. You'll take a few steps up, the girl will indicate at some point to take off your shoes, which you need to do, and put on some slippers that very likely will be several inches too short for your feet. Follow her up the stairs.
3. She'll lead you to her room. Take off the slippers before entering her room. The room will probably have a low table for sitting on the floor, and a small futon. The windows will be covered, but there's light in the room. She'll probably indicate to sit at the table. She'll bring you some tea and maybe a few cookies.
4. The business happens at the table. In many places in Tobita, they've gotten enough foreigners that they just have a price list there. Time and the cost. You can just point at the time you want. It's not cheap.
5. Then the girl will lead you over to the futon. She'll probably take off her dress or whatever she's wearing. The girl I was with just had a long sweater thing and stockings. She left the stockings on, which was fine with me. Again, unless you know Japanese, you probably aren't going to be able to negotiate such things, and at Tobita it's not really a GFE thing so you aren't gonna be able to get in a lot of wardrobe requests anyway.
6. She'll clean you up with an alcohol towlette and put on a condom for a CBJ. Then it's more or less whatever positions you want in my experience, depending on your language skills. I had no problems having her change positions or touching her normally, but I wouldn't try something that would usually require permission. You might get some mileage regarding changing positions with hand gestures. Regardless, be gentle and have a sense of humor. If you dont get off or she doesn't do what you want, don't get super-pissed off. You are representing all foreigners here, and if you throw a fit, this org and many others might decide foreigners aren't worth it.
I very much doubt that any of these girls speak much English, so definitely don't count on it. They are likely all from lower classes in Osaka, so, while not dirt-poor, they certainly aren't spending a lot of time buying Gucci handbags and going to Bali, either. The girl I was with said she'd never been to Tokyo before, much less travelled outside of Japan. Obviously it's best to have enough Japanese for transactional purposes. Greeting the women there and knowing what to say before and during playtime certainly puts them more at ease.
