Thanks for the insight... I really agree with you regarding the P4P scene in Osaka lol.
I live around Chayamachi in Umeda
Shit, right there in Chayamachi? You must be paying a fortune for rent. I don't ever recall seeing anything promising in Chayamachi, that being tourist/shopping ground zero, but there used to be some action at nights just south of you in Sonezaki (more girly bars) and if you wander east a little bit into Doyamacho I've come across a number of shady little CMPs there; word of caution, however, as (in case you didn't know this) that's Osaka's unofficial gay/trans district so there are a number of "new half health" shops and most of those "girl" touts on the street in front of Hotel Ilmonte will have dicks under their skirts. As long as you're not too drunk it might be worth strolling around the shotengai between that point and Ogimachi Park. Incidentally, that's where the meeting point for Libe Umeda shop used to be.
And again, if you go just a little south of that you end up in Toganocho, which definitely has options (housewife clubs) for Japanese and, perhaps, fluent Japanese-speaking Asians. Best starting off point would the 58 Ban-Kan, which used to house different shops on every floor, and then if you wander east of that point the next couple of blocks feature similar businesses and then love hotels further up the street. And if you strike out at every shop, are moderately intoxicated and don't want to go home empty-handed, the main Libe shop is right next to 58, absolutely accepts foreigners and you're guaranteed to go home with a fistful more than you bargained for.
But again, outside of Tobita the P4P scene in Osaka is so depressing that I'd rather just take my chances picking up broken women at HUB or horny tourists at cheap bars (whenever tourists come back again). The ideal day for me, if I'm forced to be back in Osaka, is to hit Spa World after lunch, lounge around getting drunk with the edamame snack pack combos, spring for an akasuri where the nice Korean lady usually gives my asshole a good scrubbing then go troll all those new, small craft pubs and cheap hotel bars along the JR line near Shin-Imamiya which the city is currently trying to gentrify. Cheap hotels means tons of cheap Asian tourists (again, when they come back) and I've met a number of decent looking Chinese, Thai, Korean and other random Asian girls on vacation and getting lit on their 8pm nightcap watered-down cocktails who were probably down for some vacay-dingaling if I had a wingman with me so it didn't look so suspicious.
Back in the day you could just hop on the Hankyu and jet over to Juso, which in my days was a mecca for cheap, gaijin-friendly (usually) P4P. I've heard that's not the case anymore and most of the shops have either closed down or gone full bigot, but if you have nothing better to do it might be worth heading over for some recon work.
But that's all I got for Umeda. I fucking hate Osaka but somehow, some way, I always end up back in town whenever I'm in-country...and then somehow, some way, I end up back in Umeda and then end up at Blarneystone nursing a fucking 1200 yen Guiness and hating myself for it.
