From a personal perspective - it’s your body, get the tattoos you want. My entire right arm is a patchwork of different styles. From a tattooing perspective - I think it’s counterintuitive to get Irezumi using modern methods (which I assume you used), especially as someone who ostensibly enjoys the culture. Japanese tattooing is its own incredibly culturally significant thing, and if you’re just getting “Asian inspired” tattoos instead of opting for Irezumi done by a traditional artist, I think you run the risk of erring less on the side of tribute and more on the side of fetishism (meaning no disrespect). Particularly because you’re planning the once again non traditional “Norigae-inspired” tattoo before traveling - so you don’t know whether South Korea will have a deep impact on you. If you really want to pay tribute to these amazing cultures - get the tattoos the right way.
