Demand in the Japan plant protein market is increasing since citizens seek nutritious and sustainability food. There are numerous consumers switching to plant-based proteins such as soy, pea, and rice over conventional animal products. This is prompted by the increased concern of health, environment and concern with vegetarian or vegan diets. Older people in Japan also use plant protein since it is easy to digest and very rich in nutrients. Food and beverage companies are developing increasingly delicious and convenient plant-based products, and it has become less difficult to include these products in the daily menus of people. Consequently, there is an increased popularity of plant protein.
