How to buy an Akita Inu dog?

Excuse me, could you please elaborate on the process of acquiring an Akita Inu dog? I'm particularly interested in the steps one needs to take to ensure a smooth and responsible adoption or purchase. Are there any specific breeders or shelters that you would recommend for sourcing a healthy and well-tempered Akita Inu puppy? Additionally, what are some key considerations to keep in mind when selecting a breeder or shelter, and what are the potential costs associated with bringing an Akita Inu into my home? Thank you for your time and assistance.
