ID for clubbing in Tokyo

is it ok to use a drivers license for ID when trying to get into a club ? im from the UK ill be visiting Tokyo for 3 weeks. i heard its super strict in terms of drinking.

Also does the age restriction apply to host clubs and karaoke bars too?

Since you're required by law to carry your passport with you, I'd suggest that you use that instead.

It probably would be better to use your passport as ID. I know very little about host clubs, but I checked a website for one in Kabukicho, and it said you need to be over 20, which makes sense as they serve alcohol, and they would probably get into lots of trouble with people's parents and the police if they let underage people in.

For karaoke bars, if you mean a proper bar that also has Karaoke, you will need to be 20 or over like any other bar. If you're using it as a general term for anywhere that has Karaoke like you can outside Japan, then people under 20 can go to karaoke boxes like ban ban or karaoke kan until around 10pm depending on the place.
