Raised from puppyhood w/kids and they are good to excellent. Used as babysitters in Japan, historically.
Our guy comes from a breeder in Mindoro, WI. She also runs a private email group for her owners & owners-to-be and there are a lot of families w/kids, plus this genetic line seems really tractable and good-tempered. Her website:

You can see her dogs over 2 generations. She has one stud and 3 females and does 3 litters a year. You need a reservation. Males, right now, are in short supply, with more reservations for them than puppies available.
I would say visit various breeders and study up on the breed. They are very independent-minded and take a firm hand and time to train. Not for everyone. You really have to stay one step ahead. I advocate a puppy just because then, you aren’t dealing with someone’s mistakes or trying to replace a bonded leader. This is like having a baby, though and means broken sleep for at least 2-3 months.
You want to see some of the dogs at the middle & ends of their lives, too. Some lines have hip & knee problems, some have skin probs and auto immune issues.
They have an innate high prey drive, so it is important they be socialized with the family, kids, other pets from weaning onward. They must recognize everyone in the family as alpha to them. On the whole, though, they are very loving dogs and want to please. Bright, too.
