I’m not reading the current book - instead halfway through 君の名は (side-note: how do people here feel about this or similar “body swap” fiction?) - but I have once stayed in a former love hotel.*
Checking in, choosing a room, specifying an amount of time, agreeing on the price. I think that’s how it goes? From photos and videos I gather there are some very interesting specialty ones out there, but I can’t say what the average is like. Hopefully friendly to all orientations.
My country  probably has places that could be labeled “love hotels”… but again, no personal experience there either.
First of all; on the map I had it was listed as a “business hotel”. That’s probably why -when I finally got there- I was having a hard time finding it, since I expected a different kind of building. I ended up asking the staff at the nearby konbini and while she pointed me in the right direction quick enough, I barely got an answer out of her when I asked about all the giggles and funny looks she was giving me. Maybe relevant to know: I was on a pilgrimage at the time, fully dressed in the traditional white garb and straw hat.
Meanwhile, the new owner is a friendly old lady who says she totally renovated the place. So it really wasn’t until I walked into my -accessible straight from a private parking spot- “single room” that it all clicked. The big bed, covered with red sheets and pillows, big couch in front of a TV, a bathroom with a completely glass wall… and oh yeah, condom dispenser next to the bedside. “business” eh?
