How long does a Japanese akita shed its hair for?

Akitas have a dense double coat. This means that their coat consists of an outer layer of hairs called "guard hairs" and the softer more plush undercoat. The undercoat is largely shed twice a year, in preparation for the cold winter months and the warm summer months. The sooner the Akita has all of the loose undercoat brushed or combed out the sooner it will stop shedding.
