Extras that can be negotiated inside the room is CIM (COF as well I suppose). Anal is also listed as an extra but I've never dabbled and from what I've heard, not many girls at Ginza actually offer it.

For what you pay reception, BBBJ is standard as well as DD if the girl provides it. Not all girls provide it but lately quite a few of Ginza's offerings have provided it. Best thing to do if you want to find out prior to booking is check the reviews here on aus99. Most who have reviewed the girls at Ginza have made a note about receiving DD, myself included. From my most recent punts at Ginza, Jessie, Cindy and Cookie provided DD. Not my thing, but it's a part of their routine and I let them carry on.

At the end of the day, if you want extras, ask nicely before the session starts.
