I've read that some countries don't allow unmarried couples to stay in the same room...
Can anyone please advise if there will be any problems with the following countries...?
I was just in Japan with my boyfriend two weekends ago. We shared a room in a hostel in Fukuoka. I don't think you'll have any problems there. I was also just in Hong Kong last week by myself but I don't think you would have problems there either.
If you're concerned just wear a wedding ring and say you're married if they ask. Unless it's actually illegal there's not much they can do.
If you are both non-nationals of the countries above, you will have no problems.
In some countries, like Vietnam, officially a foreigner and a local cannot share the same room. When it comes to two foreigners, there are no problems.
Do not be worry, you are safe for your list.
Having been to all of these countries except for Nepal and Cuba, I would think it highly unlikely you would strike any issues. Some religious-based accommodation forbid non-married couples in the same room, but that is an individual decision of a given hotel/hostel rather than a widespread policy.
Sweet, no worries, thanks guys. I suppose I'm just erring on the side of caution having not travelled to these regions before - and not wanting to offend the locals!
