Is wasabi perishable

Yes, wasabi is perishable. Fresh wasabi root can last about one to two weeks when stored properly in a cool, dark place, ideally wrapped in a damp cloth and placed in a plastic bag. Prepared wasabi paste has a shorter shelf life, typically lasting only a few days to a week once opened, especially if not refrigerated. For longer storage, wasabi can be frozen, but its texture and flavor may be affected.
