What is the Japanese word for pants?

Answer 1

The Japanese word for pants is just in katakana so it's - パンツ pronounced pantsu.

The romanization of the above is: pantsu. According to my Japanese-English dictionary the Japanese word for trousers is Zubon. There may be different words for different kinds, the only other one I know is Hakama (traditional men's trousers).

The above is accurate, this is just a more specific wording:

Older generations consider the word zubon ズボン / ずぼん as the Japanese translation of "pants", and the word pantsu パンツ as the Japanese translation of "panties".

Modern generations use pantsu パンツ as the Jap. trans. of "pants", and pantii パンテｲ for "panties".
