The Shiba Inu, Japanese for Shiba Inu (しばけん?or?しばいぬ) is a breed unique to Japan. The price of a puppy varies greatly depending on the pedigree and other factors, it can be around 1000 yen or tens or hundreds of thousands of yen a horse.
As for exporting, I'm afraid this problem can't be solved by individuals alone. Various countries have strict laws on the import and export of live animals, not as simple as home appliances. The domestic pet market will also have Shiba Inu, but the purity of the breed is not known. If LZ really ships Shiba Inu from Japan one day, don't forget to let me know!
