Sorry for the late post here, but I just joined TAG. I know of one sure fire place in Omiya called Aroma Body.
It’s a massage place, but it’s run by Chinese and they offer everything.
I’ve had a couple of HJs there, and took an international colleague of mine there. He got FS for 25k yen. He said the girl he got was hot, maybe 8/10. Pop and leave though. You also get taken out of the shop and around the corner, so he freaked out a bit!
All these extra options are negotiable. First time I went I didn’t have the balls to ask for the “kimochi-ii” course, but after my regular massage which was pretty good actually, the masseuse got all snuggly and turned me on enough that I didn’t want to leave with blue balls and went for the HJ.
Directions:
Head out the East Exit of Omiya Station and turn right at the bike rental/subscription place (all the orange bikes). Head down that road (it’s lined with Karaoke places, pubs, restaurants, and cabaret clubs).
Turn left at the Cocoichi curry place. Cross the street at the lights and continue up that street. Look for a building on your right that has Aroma Body advertised on the second floor.
