love hotel
A hotel intended for short stays so visitors can engage in sexual encounters. Use this tag if an image contains either an exterior view of a hotel with a suggestive name on a sign (like 休憩 ¥XXXX), or if characters in the image imply or mention that they're going to a love hotel with the building visible in the image.
Combine with hotel room if the image shows a hotel room but with elements such as a suggestively-themed bed, or sex toys on the night stand, or hotel-issued condoms in a small container near the bed, etc.
