Some other cities:
Hirakata - People seemed a lot friendlier overall than most of the Osaka City locals. Some locals I met really got a kick out of the few Osakaben phrases I had learned from my first Japanese gf, whom was born in Hirakata.
It never ceases to amaze me how small the world is. I worked in Hirakata City for three years, dated a few girls there (and hate all of them to this day) and since the day I resigned my position and caught the train home back in 2005, I've never, ever bothered to go back again.
There's a good reason people--and females, in particular--might've seemed friendly to you there. Just as how the Panasonic/National HQ sustains the economy of Kadoma City a little further down the line, Hirakata City is largely bolstered by the existence of Kansai Gaidai, which is one of the most infamous universities in Osaka and is known, basically, as an overpriced private school for predominantly-female morons, and its main attraction is a very large and prominent "international" department that sends horny, brain-dead young girls, hungry for gaijin cock, on overpriced homestay semesters abroad to Canada, Australia and America. Basically, if your daddy has money, you were too stupid to get into a normal school and your only dream is to become a flight attendant for a year until you can find a white guy who'll knock you up and take you back home with him to Los Angeles where you can spend the rest of your days shopping and hanging out with other pretentious moronic Japanese bimbos at pretentious cafes and never work a day in your life, Kansai Gaidai is where you go. And if you're so severely stupid that you can't even pass the entrance exam to the regular KG uni (meaning you probably can't spell your name or do basic addition and subtraction), they even have a "community college" on campus which basically costs the same as the real school but they have extra staff on hand to make sure you don't accidentally eat any lead pencil tips or drown in the water fountain and stop paying your tuition.
So if you're a guy in your 20s and white (or from a popular tourist destination), Hirakata can be a very fun place to be, teeming with dimwit skanks just dying to grab their ankles for a chance at that green card. I must admit, I don't know how I made it out of those three years STD-free (and illegitimate child-free, for that matter) and it was a wild ride, but I can't help but look back at that time and place with nothing but contempt.
Still, when I think back to a drunken night in 2004, getting a blowjob in the garden area outside Hirakata Station while chugging a lemon chu-hai and admiring how I'd tied my tie at the perfect length, so that it didn't impede my date's oral efforts even when I leaned forward to observe the progress (while disgusted looking old women walked by) I can't help but stop hating Osaka for just a few moments in time.
