hardworker's trousers

Hello!
As I doubt many Japanese people who will read this message can understand French, I will follow writing in English.
I'm looking for me, as well as for my wife and my daughter, pairs of "JAPANESE HARDWORKER'S TROUSERS" that are impossible to purchase in France .
Could anyone help me ? I will of course be very greatfull and will go through any procedure to be able to offer my family these items.
Any link will be helpfull.
Thank you very much!
