Shiba Inu Puppy Wanted

I'd like to buy a Shina Inu. I will castrate the dog because I only want a pet not no become a pet breeder. Im currently in Japan for vacations and I want to transport the dog with me on the plane when I depart to Mexico. Please consider me as a canditate if you have one available because me and my wife love Shiba Inus but never had the chance to get one.
