It is a shame. Originally La Siora and other Jaoanese Clubs all had their own dungeons or as they are often called playrooms but about 10 years ago the police arrested a mistress from La Siora and now none of the clubs have playrooms. Therefore as was said most play happens in normal love hotels. However in Tokyo there is a famouss BDSM themed love hotel - the AlphaIn - which is often used for p,aging. S3 is another option. AlphaIn has a website so you can see the rooms which are themed eg medically. S3 just has two rooms with various crosses, spanking benches, hooks on the ceiling for suspension etc
In Hong Kong and Singapore too play is typically in a love hotel or a normal hotel. Hong Kong does occasionally have dungeons available for hire. I am not aware of any in Singapore though I have p,aged in a private dungeon. I also p,at sometimes in a private dungeon in Hong Kong that is used for play parties
London is all dungeons and these are pretty standard with lots of equipment and suspension points
