First Trip to Japan (Tokyo, Osaka, Kyoto, Tokyo) 20 Day Itinerary

As a longtime lurker of this subreddit I appreciate all of the inspiration and discussion shared by this community. I hope this post may lead to some inspiration, and that any guidance shared in the comments of this post may help other too.
I am planning a trip for roughly 3 weeks from mid-march to early April 2024. This trip will mainly be solo, though I do have a few friends there who I may join join some days.
**About me**:
I am a semi-active male in my late twenties. I know some very basic Japanese words. I am really excited about seeing the historic architecture like temples and castles, natural areas like gardens, and the city views from skyscrapers or streets lined with colorful storefronts. I can also geek out over techie experiences, like immersive rides or virtual reality experiences. I am really looking forward to trying a lot of foods that are not readily available at home. I would enjoy opportunities to socialize. I would usually prefer to stay sober; Though, I could be comfortable with one drink if it is required to be somewhere.
**Flight**:
I intend to fly in and out of Narita airport.
**Trains**:
I do not plan to get the JR Pass. I will take this train from Tokyo to Osaka, and from Kyoto to Tokyo. I do not believe this, and the other shorter train and bus rides covered, would outweigh the cost.
**Flexibility**:
I am comfortable moving days around for anything that doesn’t require prior reservation. I have also tried to keep at least one low priority day per area in case of bad weather or if something else were to come up.
**Hotels**:
In Tokyo, I plan to stay at a hotel in Akihabara.
In Osaka, I plan to stay in a hotel close to Dotonbori St.
In Kyoto, I plan to stay in a hotel in the Nakagyo ward.

**Questions**:

* For bars that have a minimum drink limit, is there a common non-alcoholic drink that can be ordered to satisfy this requirement?
* Are there any bars or social spots you would recommend visiting?
* Do you have any recommendations for safe and welcoming environments for dancing?
* Are Tokyo, Osaka, and Kyoto good cities to just walk in a direction and adventure in? This would be for both safety, and points of interest.
* Do you have any good food recommendations for the areas I will be visiting?
