I ate 4 bags of the Kasugai wasabi peas in one afternoon and it messed up my taste buds for about a week. I couldn't taste anything on the front of my tongue and it felt kind of rough. Please be careful. Also, I used to eat the Taiwanese wasabi peas a lot, but after this experience they taste like nothing to me; I think I have messed up my wasabi pea sensitivity. Despite this, I still eat both kinds frequently.
