The Japanese walnut is a tree with multiple benefits, but also a few significant drawbacks to be aware of:
The nuts are edible, sweet, and have an oily texture. They can be eaten raw, cooked, or used in confectionery. An oil can also be pressed from the seeds.
The Japanese walnut has larger leaves and round nuts, whereas the butternut has oval nuts. It is also resistant to the canker disease that plagues butternuts, which has led to it being planted as a replacement in North America.
