Hi. I think your issue arises from the differences in physiology, rather than sexuality. Japanese women are normally petite, with really pure skin, and dainty movements. Western women are usually taller and broader, have varying skin tones, and more more confidently than their eastern counerparts. I think it is the difference which is so apparent to you, having spent so long seeing one rcial type, and then seeing the other. i am sure the same applies to anyone who lives with black people for a long time, and then returns to a white nation - the 'culture' shock is probably similar. So, i don;t think that western women look 'man like' - just different.
