Masaharu Oki has published numerous books and magazine articles, and conducted lectures throughout Japan.

It is my idea that the most important theme is for us to live happily with our beloved dogs and the dogs should be healthy for that purpose. First, we must “understand the dog”, and the basic idea is to give natural food, which is closest to natural food without artificial additives. The CEO of BIGWOOD, Masaharu Oki provides instructions free of charge, thus you can benefit by what he has learned from his years of experience and research. We will always strive to make an effort to help you have a fulfilling life with your beloved dog.
