Why japanese designs of robots are weird?

Why japanese designs of robots are weird, freaky,too round and alien looking and just not like something a sane human would make like a boxy nice square ugly terminator with gauss rifles that kills anything on its path. I mean every video of japanese making a robot they made the robot gay looking too round white and has an alien face like this:

or just the terminator from T2 or something else that is more human like (square and ugly with jagged edjes that can ccrack someones skull) like a CL4P-TP or Megas XLR and those ugly Glorft robots from Megas XLR
