If you have ever travelled with friends or family, chances are you have seen someone knock on the hotel room door before entering, even after checking in.
At first glance, it may seem unnecessary. After all, the room is expected to be empty. So why do many people still do it?
Across much of Asia, knocking before entering a hotel room is a common practice rooted in culture, tradition, and courtesy. In countries such as Malaysia, Singapore, Thailand, Hong Kong, Taiwan, Japan, and China, many people believe it is respectful to announce their presence before stepping into an unfamiliar space.
For some, it is linked to long-held beliefs about unseen spiritual occupants or lingering energy in temporary places such as hotels. Knocking is seen as a polite gesture to avoid disturbing anything already present.
The ritual is usually simple:
- Knock a few times before opening the door
- Say phrases such as “excuse me” or “sorry for disturbing”
- Turn on the lights immediately after entering
- Open the curtains or windows
- Flush the toilet or run water briefly
These acts are often symbolic, meant to create a welcoming and comfortable environment.
For others, the habit has little to do with superstition and more to do with routine. It can be a way of entering any new space mindfully, with a sense of respect.
Interestingly, hotel staff also follow a similar practice for practical reasons. Housekeeping teams are trained to knock, announce themselves, and wait before entering to ensure privacy and avoid surprising guests who may still be inside.
Whether viewed as tradition, etiquette, or personal comfort, knocking before entering a hotel room remains a small ritual many travellers continue to follow.
At the end of the day, it reflects one timeless idea: wherever we go, a little courtesy never hurts.
