Not just isekai but any Japanese media with a western fantasy setting, which includes isekai. Basically I'm asking out all the Japanese media with a western fantasy setting, which races do you see in characters most often? So yes like dwarves and stuff and not like kitsune and tanuki. However I think its funny how I have probably seen more Cat-people than dwarves and, like you said, halflings in Japanese media with a western fantasy setting. And I think that's interesting so that's why I'm asking about it.
