No. In Jain dharma, tapioca is generally not eaten because it is a root vegetable. Jain dietary rules avoid roots like potato, onion, garlic, carrot, beetroot, and similar underground foods, as they involve more harm to living beings.

If by “tapioca” you mean sabudana, that is also usually avoided in strict Jain practice, because it is made from tapioca root.

So, in general: Jains do not eat tapioca.
