Tinkerbell is only if you are into the gyaru and tattooed type but its still very YMMV. Plus i really think that you need a lot research to get a safe bet
Harvest Moon operates slightly different from what we are used to for payment. You pay the store the bathing fee, the rest of it you pay directly to the girl *wink wink
Susukino is notoriously expensive due to all the different additional fees.
Way to complicated for me, i would rather go to shinichis in Osaka than visit the soaplands in hokkaido
It's a lot more common these days because more girls allow you to bring them out if you book 3 slots or more, something like a date course. Tried it once but probably wouldn't do it again
Honestly, i find that sapporo is way too expensive and not really worth the price. 32k yen can get you maybe even 2 x 60min in yoshiwara and kawasaki/yokohama.
For soapland in general really not the best idea 😂
The shinichis in Osaka on the other hand is ok since you get to see the girls with your very own eyes but as usual YMMV 😂
Quite sure only japanese ppl can access it, i only managed to get in because, asian, speak japanese and most importantly i knew mayuri, although she has since left and it working back inside tokyo again
