Are they the same as the asian deer that are in Southeast asia and the Island offshore there? From souther Japan down. the antlers look the same......jk
I think you might be thinking of something like sambar or rusa deer.
I was on a little island near the Cambodia /Thailand border a few years ago that was crawling with deer. Definitely not sika deer, some sort of sambar or rusa, they were little guys, maybe 80 pounds.
