Tattoo in Mt. Komorebi and Tomarang?

In my head, I got this picture of tattooing being an old tradition in Asia, so in my game I plan to have a tattoo shop focus in the worlds of Mt Komorebi and Tomarang, that I play as the Empire of Snorthia. Is anyone else thinking along these lines?

My problem is that hardly any lot in Mt Komorebi is suited for the small business combo, so I will need to do some adjustments there. I will be happy with just one parlor in each world, but I also want to add some tattoo elements to other lots, just to make that old tradition feel more like a community thing. Hopefully there will be at least a few posters with tattoo designs, like we saw in the trailer.

I don't know much about this in real life, but if tattooing is respected as part of the culture, it would probably not be wrong to implement certain routines for the emperial family, too. Then I think I must find designs matching with what my "protected families" were gifted centuries ago, like the family protecting the dragon should have a dragon tattoo, the family protecting the silk worms could have a butterfly tattoo, etc. I did not see many typically dragon tattoos in the trailer, so I'm curious to find out if I can create my own by importing images etc.  A free hand in-CAS drawn dragon would probably not please the Emperor that much, LOL.

Because of this I also look into having a tattooing academy in Mt Komorebi, or a system of foreigners going there for a couple years to learn the art from working as trainees at tattoo businesses. Just need some more info before I decide...

Is anyone else m aking up cultural and/or traditional stuff regarding the tattoo business?
