Based on this description below:
Vegetarians do not eat meat, fish, or poultry. Vegans, in addition to being vegetarian, do not use other animal products and by-products such as eggs, dairy products, honey, leather, fur, silk, wool, cosmetics, and soaps derived from animal products.
The word for vegetarian which I know of is : 菜食主義者
Is there any word to described Vegans in Japanese as described above?
