Osaka Bars/Pub crawls

I’m a 24M visiting Osaka for about 5 days over a weekend and was wondering if anyone has recommendations for good bars or bar crawls where it is easy to meet people.

Nothing crazy, just looking to meet some new people to grab drinks with and go out. Open to hanging with other travelers, locals, guys or girls.

Also curious if it is normal to go to a club alone in Osaka or if that would be considered odd. I should also mention that I know zero Japanese.

Appreciate any suggestions!
